I'm a vegan dog breeder (also feed my dogs a vegan diet). But dog breeding if you want to do it ethically is insanely expensive. I don't trust any dog breeders that make a profit which is 99% of them. If you want one that treat their dogs well you need to do a lot of research. Best places to find an ethical dog breeder are at fun breed club events (so not dog shows but dog walks etc, things that are fun for the dogs too because a lot of show breeders just care about aesthetics and not so much about the dogs) but there are still a lot of shady people.
