A Very Confusing Problem With Our Dog

[ray23]

I really need some input; I have had dogs as pets for at least fifty years. I have ran across one that I fully do not understand.

He is a 3& 1/2 year old mutt. It look like he might have some Rot wielder in him, based on his markings, none of the other pups in the little look similar r to him other they some are short haired and black in color. The other were wire haired and grey in color.

Has been a hand full from day one became so aggressive with the family that it was down to change something to get rid of him. I was able to obedience train him to some degree but it was a fight all the way. Unfortunately my wife has no experience with dogs and it was catch a catch a can, in maintaining the training. For the first time in my life I had a dog castrated and it did calm him down a bit. But he still would growl from time to time. And do warning snaps at my wife no me. Some of it was here fault she was antagonizing him. She has no idea what she is really dealing with. The dog is 55 Lbs. and its all muscle.

I could play with him and when the biting got too hard I would quietly remind him and he would gentle down.

About two months ago he developed something and illness, in the evening hours he would begin panting like he had just ran ten mile in the heat and his heart would just be pounding. There would absolutely be no controlling him, he was in panic. This has never happened in the daytime, nor has anything changed in his environment.

We brought he Vet out and he tried medication, didn't work so we took to a place he could be x-rayed in an effort to find out what was wrong with him. There findings were that he had a narrow wind pipe and the right side of his heart was enlarged.

So both of the vets can me up with a new medication that seemed to help briefly. But at the moment he will have one good night out of three. My belief is he just exhausted on that night.

Now it is being recommended that we take to from Udon to Khan Kean where they have computerized array equipment, to try to get a better diagnosis. Problem is the only way your going to get this dog into the pickup is with anesthesia. He has been through that now three times he knows what is coming and wants nothing to do with it, so a major battle every time. . We noticed that during these attacks he was constantly looking at his butt. So he been checked for every virus and infection know to man, nothing

Here I where it is getting confusing to me, Ok he developed a narrowing of the wind pipe and his right heart developed to an enlarged state. But why does only have attack at night?

The one vet speaks good English and seems to be very sincere. But, when I talk to her she talks about the trip to Khan Kean resulting in a different kind of medication. When she speaks to my wife she speaks of surgery. So nothing very clear there.

We seem to be talking about somewhere between 2 and 5 k baht, so it’s not the money. But I know what I will have to out the dog through just to get him to Khan Kean and there does not seem to be clear direction of what is going to happen from there other then some tests are going to be ran.

We have been taking turn at night taking care o him, but we are totally exhausted.

His behavior ha changed immensely all of sudden he jumping up the counter to take food. Last night he took a dump in the house. He had been out of the house numerous times through the day and evening. He didn’t even do this when he was a puppy. When I tried to control him, he definitely went into an attack mode.

The family has to get some rest we are at wit end so if the attack hits tonight he is going outside, He will be barking but it’s a very strange bark, that cause the other dogs in the neighborhood to howl. We will talk with our neighbors before we do this. They have never complained in the past. Bu we try to be good neighbors and that is why he has been brought in during the night. I fit bothers them then it will stop, I refuse to expose them to what is really our problem, so we will see.

But I’m defiantly at a juncture where I have to make some hard decisions; I don’t want to see the dog continue to suffer is there is really no hope. Which I will mean putting to sleep, again nothing I have ever done before and not something I take lightly.

But, I can’t get a clear picture of what lies ahead and pretty confused at the moment any constructive input will be appreciated.

Wow Ray, that's a very sad story. Can imagine how worried you are.

Although I have no idea what can be wrong with your dog, something in me is asking if it is possible your dog has developed a tumor (or two). Cancer/tumors can cause increased appetite without the dog gaining weight and behavioral changes. But how that can be related to a narrowed down windpipe and enlarged heart? Unless there is a tumor on or in the windpipe and heart. But this is wild brain storming as it should be visible on the X-rays, so far I know.

Why only in the evening/night? I don't know. It is quite clear to me, though, from what you write, that your dog is very much in distress.

Has the vet done blood tests already?

An option for bringing him top Kon Khean. Get yourself a solid cage. Have the cage somewhere away from the car. Get some heavy muscle men (and women). Get the dog in cage. If your dog loves treats (BBQ chicken, pork, baked liver) then use that to lure him in or close to the cage. You might need a day or so to get your dog's trust that being in the cage doesn't mean confinement, that is you put the treats in the cage, the dog goes in to eat it and can come out on his own account.

Once your dog goes in the cage on his own, close the door and lock it. Load the cage on the pick up (watch your fingers!) and tie it secure. Drive to Kon Khean. You may have to ask your vet for a light sedative which you can put in a delicious treat. And you may have to tie your dog's mouth for your own security when handling him.

Put both a leather or nylon collar AND choke chain on your dog; in case the collar breaks you still have your dog on the choke chain. In case he bites the lead, use a chain.

Hope this helps, and I wish you good luck.

Justa reminder of how powerful these forums really are. From these positings ran into a retired Vet from the UK who lives in Udon and this is his response

"Ok, here is my 2 bobs worth.

The large heart is cardiomyopathy ?? and it causes major health issues, such as pulmonary oedema,, ( fluid on the lungs ) and a back pressure with it, causing his shortness of breath.

Now i dont know the anatomy of this dog, but the enlarged heart can cause movement of the 2 main brochioles ( windpipes ) that bificate from the trachea ( main wind pipe )

so u get a shift in major anatomy within the chest cavity. This would account for the chane in his bark ( more high pitched ? ) same air being exhaled , but going thru a smaller tube.

Sleeping at night, in the wrong position will cause breathlesness, as the fluid on his lungs will gravitate to the lower bases of the lungs.

The CAT Scan ( no pun intended ) would pick all the anatomical changes, and they might suggest a bronchoscopy ( tune down his windpipe ) to view it all. he might have abnormal anatomy ( growths / cancer )

They would probably suggest a diuretic to assist with the fluid on the lungs ( lasix / frusimide ) maybe some brocho dilators ( ventolin / Pulmocort ) and a possibly Digoxin to reduce his blood pressure a bit to relieve the work load on his heart.

The aggressive presentations and mood swings can be put down to a simple reduction in the O2 in his blood ( hypoxia ) caused by the above.

If u notice his shortness of breath after small excercises, i suggest all of the above might fit ur dogs clinical presentations.

The KK Univeristy has a good VET faculty and was one of the Uni's used 24/7 during the bird flu crisis. It has a good reputation and worth the visit."

So the answer is get him to Khan Kean. The cage is a good idea, I won't have any problem getting him in one. The problem is goign to be when they try to examine him. He won't hold still long enough for them to do the x-ray. or the EKG. We have tried sedatives in the past and very strong ones, administered by the vet no way. So I'm afraid it's night night or nothing.

Thanks for your help The specialist is only there on Thursdays so we will try to get an appointment set up tomorrow.

[elfe]

i wish you and your dog good luck for the trip and examinations and that they find the cause and can treat it good. am having similar problems at the moment with my 5yr old great dane who might have heart problems or a tumor (hope not!!). also the panting, losing weight, no power and fluids in the abdomen and maybe lungs. also the high pitched bark which i only came to think of while reading your thread. i'm off to bangkok to a good vet hospital as soon as possible in the next few days with him.

[ray23]

Well I wish you well to it's amazing thing to see the dogs been fine all day at 2100 hours it kicked in again. I'm told that is another symptom common to the problem

[Carib]

Ray, I have had dogs all my life, worked with them, have been an instructor for behaviour lessons, just saying that I do know something about dogs.

You have not only got a sick dog, you have got a dangerous dog.

I quote: When I tried to control him, he definitely went into an attack mode. Unquote.

The possibility exists that one of these day " something" will happen inside the dog, which will cause it pain.

Something you will not see or notice, and usually those things are not understood by the dog too, and than there is a big chance the dog will take it out on someone else, who for instance just tried to pet him at that moment, or did nothing at all, but is just there.

And from what you describe he has the built of a strong dog.

I absolutely applaud you for the trouble you and your family are going through in trying to take care of this dog.

But from what you describe I see what could be a ticking time bomb.

I urge you to please be very very careful .

If the dog needs an operation, and that can be properly diagnosed/established, get it done as soon as possible. For you and your families sake as well as for the dog.

This may sound pessimistic, but I have seen the results of more or less similar things.

Good luck.

[bina]

what sedatives dont work on your dog??? does your vet use zoletiel??? its a safe enough anesthesia but of course being used on a dog with a heart problem could be problematic.... but we only do xrays with anesthesized dog, the pics come out better, and less stress on patient.... however to do ekg u need a cooperative dog... so the treatment outline might work w/o the ekg...

the part the puzzles still is it possible that he has also a brain tumour or pressure on the brain as this would cause changes in behavior? i unfortunately agree with carib here, and re state what he says: given the fact that the dog is big, and u do have kids at home, this is a time bomb waiting to go off..

pain is a good reason for a dog to go aggressive

brain tumours could cause behavioral changes

never thought about hypoxia but good idea

its possible that one problem was existing and then an other developed thereby triggering the strange behaviors (had a mild heart problem, has tumour in brain, lack of oxygen on a oherwise compromised brain... etc.. far fetched but have seen several combination problems that made a greater problem...

bina

[ray23]

Bina I'm not sure what sedative he is using. I thought there would be a problem wiht the EKG and getting a true result, with the dog under the influence. So my guess is the best we can hope for is the computrized x-ray as it is explained to me, Never heard of it before.

I'm a retired cop, don't know the first thing about a Vets practise but I have been around a lot of emergency rooms. So I have seen the efffects of drugs on people. It woudl seem to me if you did an EKG on me at the moment, the results would be much different then if did while I was under anateasia ( sorry about the spelling)

Aggression:

I noticed that early on, that why he was castrated and it did in fact calm him down. I did the obedience training wiht him a a norm he will listen to me. But the other night had I not known to pick him up from the back and get him off the ground, where he couldn't get a position to bite I mihgt have very well been bitten. So I am watching things very carefully. Normally we had at a point where he was playful, but gentle in dealing with us. The real problem is my wife no matter how many times I say it she just doesn't get it. He went through an episode last nihgt and was bask to what like his normal self this morning. But the fact is he is sick and grouchy. So what does she do pokes on him to get him to play, you guessed growled turned his head to bite, it was a warning and I stopped her.

The truth is her lack of understanding scares me worse then the dog. I have told for 3&1/2 years. I told her one bite from that dog and you can lose a finger. There are no children around the house or he would of had to go a long time ago. we are in the first stage of adoption which takes about two years. The dog loves kids, but I woudln't take that chance. So if we are succesful in adoption and he calms down we will find him a new home. If not I won't pass on the problem.

We will see what happens with thi next examination, but I'm really not expectign miracles.

Bina is it true that Vets here will not put dogs down. when there is no hope left?

[Nienke]

Ray, I would discuss with the vet about the option of putting the dog to sleep. It often depends on the situation of the dog's physical and mental health whether a vet is willing to euthanize an animal. Nonetheles, some vet's in Thailand still refuse to euthanize due to their Buddist believes (in all respect).

IME, vets in CM do euthanize those animals that are in their final stages of life, and can't live a humane life anymore. I also know of a few cases where highly aggressive dogs were put down (although IMO proper behavior modification could have had prevented these fatal decisions. ) I do not judge your case as I don't know much details and haven't seen the dog. You are the best judge in that. None of us can with the little info you have provided till now.

Now your dog is sick and as a result of that he shows behavioral chances. I suggest to not worry and speculate too much. Just take it one step at the time, that is getting him to Kon Khean and then take it from there. There they most probably have considerable experience with dogs behaving in similar ways as your dog.

I have handled a few times dogs that would bite everything and everybody when forced on the table. With the help of the vet's assistants we always managed (sure enough the dog's mouth was tied at all times). In my case, I ALWAYS stay with the dog and help handling him/her. The dogs know and trust me, therefore I find it a must to be with them offering my support. And I can see that this certainly helps cooling down the dog.

And for the arrival of a child; already now (that is after treatment of your dog) you should start with changing the lifestyle of your dog to one as if there is a child around. Of course, after you have evaluated if the situation would be safe enough when having this dog around.

I wish you lots of success again with bringing your dog to Kon Khean and handling your wife. :D IME, it is often more difficult to 'train' the owner than the dog.

Oh, and don't forget to bring a pot of 'namman Ohsakathip' (น้ำมันโอสกทิพย์). When you receive a bite from your dog put this on immediately. It will take away the pain almost immediately, prevents lots of swelling and infection, and helps the healing process speeding up. Of course, don't forget to clean the wound first.

Defiently good toughts. Having been here for six years I understand and respect the Budhist beliefs. Well at least as well as a good Free Will Baptiist can

We have had the dog around children he might lick them to death. But that was before he was sick. I think woudl more be moer worried about him knocking a child down form being excited, he just loves them as a norm. But again that is when he is not sick.

Kind I send my wife to you for obedience training the do is much easier Be nice guys thats just a joke.

We have a mussel it's no problem getting that on he is used to it. Two things scare the hel_l out of him The pickup and Vets. We will just have to see how it goes.

We are going to take one step at a time and se how everything unfolds

[bina]

sorry, my grammar goes late at night...

xray digital is just an xray but put on disc and u see it on computer, infinitately better quality then the old style developed prints (oh no, over exposed, again...! have to redo the xray.... )

ekg, not anesthesized; however, u have dont have to do the ekg on the table, and have done it on the floor for large or frightened dogs... but they must be calm to get a good readout... and a skilled vet to read and understand what he/she's looking at... and a halter test might be done which is a 24 hr test with him wearing an instrument to monitor his heart for 24 hours...

i dont know... sounds a bad combo w/wife disregarding proper actions with a large dog and behavioral problems... healthy or not.... i know thais dont like to euthenize animals but have also seen that they have no problem whatsoever in killing a nasty dog or a dog that has got in to the chickens or the garden. so there are more ways then one of dealing. not condoning, just mentioning... i saw my husband (thai) go after a stray dog wandering around the kibbutz who is attacking the small dogs (and no one has been able to catch this dog, not even the county dog people), and my husband meant business since this dog had managed to grab our small male. (he lost fur but nothing else).

given the situation and in future adopting a child i' m not as optimistic as nienke and also, i personally have a hard time trusting a dog (or any animal) with small children who has had aggression problems for whatever reason .. i'm one thing, my family and kdis are an other cause i cant control their actions or help them read the animal and even with the best re training and medical care, some wierd thing can trigger an animal (as well as a human, as people go ballistic with tragic results also) in to a 'rage' again ...

[ray23]

Thanks Bina at best the adoption is at least two years away, if it is apporaved. Remember I'm a farrang they are very careful when there is farrang involved so it may not happen. Time will tell and yes my family comes first.

I have ben told the is a Vet in town that will put animal down if three is good reason. Or I could take him to the country and let him chase chickens. Sure hope I don't come back a a pig in my second life, don't stand a chance around here

[ray23]

Well we went to Khan Kean with the dog. All I can say it is the best I have seen anywhere. We arrived early as we were told about 1530. They did the EKG and X-ray, before the doctor got there. Another blood test and finally someone bothered to get his temp, which was extremely high. I have to tell the people who did the initial tests were excellent, we muzzle him I knew he wasn’t going to like a blood test. Really that was done efficiently and didn’t bother him much at all. But when they stuck that thermometer up his bumm, things changed. They and I were very grateful for the muzzle. All the testing was done without drugging the dog. They know their business.

The vet took his time with the dog, no problems with the heart and nothing wrong with his windpipe.

Diagnosis:

Acute lung decease brought on more then likely by an allergic reaction to pollen.

He changed the medications which we gave to the dog as soon as we got home. He reacted to the new medication quickly and for the first time two months got a good nights sleep. That was passed along to us and we were very grateful for it.

We have been racking our brains trying to figure out what changed in his environment about the time he got sick. Only thing I can some up with, it was about the time rainy season started.

The second, I smoke so he is not allowed in a room where I am smoking now.

Cleaning we a have a great housekeeper, but she can not see a thing above eye level. I’m always on her case about it. We started painting about a week ago and I was patching an area by the upper portion of a cupboard above the stove. It had obviously not been cleaned in three years; it was developing new forms of life. I went right through the roof on that.

Well the truth I my standard of clean is much different then my wife’s and probably most village Thai’s. So until something gets bad no one really listens. Then I get it the way I want it. So the aircon filters will now be cleaned bi weekly. As long as I stay on them, the tops of closets will be cleaned now. I really l don’t like doing that, it’s the wife’s areas to run the household and I prefer keeping my mouth shut. But, that no longer seems like the right approach.

I watched him closely today he was fine until came into the office where the air was going; you could see the beginnings of an attack. Took him out the room and he recovered quickly. He really is pretty much back to his old self.

It was a very traumatic day for the dog, begging with the cage. Someone posted and idea to get him in and we tried it a dog treat in the corner he fell for it. About halfway in a gentle push job done. Then the cage went in the truck we secured it. We had tried something different the day before used tow leashes and centered him on the pickup with that, he actually did pretty well with that. However we knew we were going to go through rain on the way to Khon Kean, so we had to put a rain proof tarp over his cage leaving the rear end I open so he could see some what. That really freaked the dog out, he started barking and howling just a soon as we backed out of the yard. So for 120 Klms he kept it up.

At one point I go a bit worried as it go quiet, remember we had been old his heart was bad. I had to blow the horn at a car and he went right back to howling, well now that’s good haven’t killed him yet.

It really to bad he hates traveling so much as soon as we got the and let him out of the truck, He headed for right for new bushes, he was one happy camper.

In between the tests I walked him and he was enjoying seeing all the new things.

I knew things were not going to be so easy to get him back in that cage again. But, we tried the trick again, after few mins. Looked like it was going to work. So he half way in and I give him the shove, darn cage slipped and the fight was on. The growling started then, I jut told him to stop it and he did. But he was definitely going to fight going into that cage. He is 55 lbs of pure muscle and got for legs to work with, not an easy task. I finally remembered my childhood time on the farm of getting horses and cattle into trailers. You can actually winch them in if you have to. But, normally one person pulling and one pushing will do the trick. So I put the leash through the back side of the cage, auntie pulled I pushed just took a second. Off we go another 120 Klms of howling and barking this time he didn’t stop for a second. No problem at all getting him out of the cage when we go home.

I was very close to putting this dog down I’m really grateful I didn’t.

So now we wait and see for two weeks if the medication clear things up, if not we go back again.

The cost for the hospital including tests, examination and medication was 1720 baht

We also found out in this process that Mitrarp road is what we know and what you will see on maps, is Hwy 2. There is a huge sign along the roadway on the right and in English.

[bina]

good going.

but then, what was the meds that he was getting before, and if that was causing the behavior changes ??

and if his temp was high then why???

what was his blood work? to what is he reacting?? dogs dont get asthma but do have lung problems with smoke and pollen but why would that cause total aggression??? was there anyone there to explain that to u, its making me really curious cause if we ever have a patient like that its good info to know...

I believe the agression came from not feeling well, the rest I really don't know. He has always been a handfull but nothing I can't handle. If the wife would follow up with the obedience training he was given in the first place. I think we would be looking at something different as of now back to the norm. Doesn't take anymore then me saying something to him. Believe it or not if he gets stupid a few days of me not paying any attention to him and you won't see again for months. He is assertive but payng attention to his actions before they get out of hand has worked thus far. When he growled at me yesterday I just told him to stop it and he did. But had I ignored it more then likely it could have gotten out of hand. Even the day he went into the attack mode I could control him easily. My honest opinnion the wife is a big contributor to his actions. She thinks it's funny of course she has never been bitten.

[Nienke]

Very glad that things went well and your dog is already doing a lot. That's an enormous burden dropped from your shoulders, as from your posts it is very clear how much you care for him.

I wish your dog a speedy recovery.

Nienke

If you need some info on preparing a dog for the arrival of a baby and introduction of a baby, feel free to send me a pm.

[ray23]

Thanks I will do just that. He is having a problem again tonight I think it might be the aircon. I put him outside, he is not happy about that but he is breathing better. Just have to watch and see what works beast.

Thats twice today getting him out of the aircon has worked.

[bina]

makes me think u ought to check out the a/c if its affecting him it could affect u also? maybe mold/mildew build up? also, did they do the ekg with him laying on his side? the few times we've done them, including my own Nala (RIP), they dog had to be standing up on all fours...

and still sounds problematic if the dog is really only 'your' dog and your wife teases him... that could be an accident waiting to happen and then all of a sudden people will blame the dog.... i know its really difficult. we have really cracked down with foofoo but anon insists still to play fight with him, pulling foofoo's bangs (hair over his eyes), tweaking his balls, etc. although foofoo knows to play rough only with anon, he does react to other people putting their hands near his head because of the bangs tweaking...anon thinks its hilarious but my kids dont enjoy having a growling lhasa apso when they have friends over. i basically told anon that if the dog bites a child, police will be involved so he has to play differently with the dog, with toys, or even rough play but must stop the instant the dog growls or bares his little teeth. the word 'police' made an impact. the teasing has been reduced. foofoo is less 'growly'. also, he now has a bed. and anon, who used to annoy foofoo when the dog was in the bed, has learned that dog in bed is a dog off limits, for time outs, etc.

training husband is much more difficult than training foofoo. be firm consistent and persistant. it pays in the end.

Boy thats good point cleaned the filters yesterday. Might be time for me to take a careful look.

Oh the dog may listen to me but the wife

One of things that has amazed me is I'm the one who desciplines the dog. Wife feeds him all the time and really does give him a lot of love. I'm the one he comes to when he is sick. I actually thought it would be the other way.

He really was aggressive before we had him cut, after that he really calmed down. Only problem we have now once some one is in the house, is he drives them crazy to play.

I really worry moer abiout our other dog biting people, He was a typical Thai dog, that someone go because he was beautiful, then did nothing with him. Ran all over the neighborhood. They moved and jut left him, so we took him in. We had, had contact with him befoer and he wa affectioniate with us. But very teritorial once he actually had a home. He is really scared of people. You have to be very gentle in controlling him. Eventually if people will just leave him alone he will warm up to them. But he is not one to walk up to and just pet.

We had an incident with him I stress these dogs not being outside alone. It's hard for Thai people to understand they are not like soi dogs. Just because they are loving with us doesn't mean they are with others or other animals.

Aunt is visiting we have repeated 90 million times be careful when you open the gate. She isn't watching one day out goes the other dog, about the same size. Thier is a bitch in heat about six doors away. Now she h been going yp to the fence sticking her butt in his face. Well he han't been cut, so he isn't real happy about the other male dogs hanging around.

There si a soi mutt on the next street over that has been messing with our dogs when we walk them o for over a year. Getting to the point wher he dog is coming o our house to antagonize them, knowing they can't get to him.

Well our dog does what any good dog would do, he is enjoying the nieghbor lady. When up comes the soi mutt, he runs him off one time and goes back to more important things. Wells rupid coms back we had never let the dogs go aftre him, guess he thought he wa save. We thought he had killed him turned out to be eight stiches. Auntie watches the gate now.

One dog in the area has already been killed over the bitch in heat, which is a pit bull, not agressive at all. Boy I'm anxious to see what the puppies come out like that is one loose lady

[Nienke]

Pricipal of the positive reinforcement. Pay (special) attention to the things she does good (which is very subjective anyway). A kind of click-treat/sniff kiss, click-treat/bunch of roses, click-treat/shopping etc.

Very possible the dog sees you as the one he really can count on in times of need.

I really worry moer abiout our other dog biting people,... ...He is really scared of people.

I can understand that you are more worried about this dog biting, as fear aggression can be unpredictable.

Same as with your sick dog, very important they see you as the great protector of the pack, someone they can rely on in times of danger. Fair, honest interaction and consistency are the keys.

Aunt is visiting we have repeated 90 million times be careful when you open the gate.

Maybe a double gate with a neutral area in between is an option?

Got to be careful there that one does bite

I think the gate problem is resolved the dog came back covered in blool scared the heck out Auntie.

Most time we just seperate the dogs from company. No matter how many times you tell them to just ignore the dogs they won't. The one that is sick one pat one the head and he will crawl right onto thier laps all 55 Lbs of him.

Got to tell you these posts are a lot more fun then the first one.

'dont shoot the dog' by karen pryor... nienke-- very good!!!!

i believe in double gates. it started when i worked in the petting zoo; used it for my boxers, and keep it up with foofoo. its also a good buffer zone for unwanted people coming around the house... u can let the dog out , unwanted person sees horrible dog but dog cant get out or at the person, person goes away. good for mother's in law problems too...
