A few years ago when we had pets in the UK I noticed something about their healthcare and mine. We had many pets over the years. Dogs, cockatiel, ferrets, rats, hamsters of various sizes, gerbils, chinchilla, rabbits, guinea pigs and some I've probably forgotten about. Oh and a terrapin which looks more like a turtle to me which my daughter still has that's moved from a small tank to a big tank and now to a pond I could almost swim in. It's bigger than the turtles I see here. This mostly affected the dogs and ferrets but if there was something worrying us about them we phoned the vet and they would often say "bring it straight in and we'll have a look". I had to get an appointment, at the doctors, not the vet, although even then when the NHS was working better it might have been an option. But then I was going NHS, they were going private.
As for our dogs, the wife does that but it's mostly chicken or fish and rice but we did start using dry food. It was a Thai brand, don't know which but it was in a green and white bag. When we could no longer get that we started using Pedigree food which wasn't too expensive in a 20kg sack from Lotus's. Our dogs are now mongrels of terrier to fat corgi size.
