It seems that you want to have dogs, but you have no idea how to train them. Your dogs are bored, so they tear everything apart because you don't look after them enough... just feeding them twice a day isn't enough. I adopted a dingo puppy from a dog shelter 3 years ago and he has learned to behave outside the gate in the village. First try the 5 basic commands: sit, come, no, seek, fetch.....and do it over and over again! My Dingo Lady can go in and out when he wants, but that takes a strong hand and patience! I know what I'm talking about.
