They're not talking crap about him for the fact that he is a dog, it's because of his personality. It seems like he's using Kouki and I'm sure a lot of people are feeling very iffy due to the fact that there wasn't super clear consent between the the two. I think it's a bit of a reach to claim that the people not liking the character are dog abusers.
All the people talking crap about the dog are the same type of people that ended up burning and cutting him. I’ve seen so many crappy people get a dog (some people multiple times) then thrown them away when they don’t act like the people want them too. I say good for him for standing up for himself
