>>Dogs love completely unconditional.<<
Stop feeding them and see how long that lasts.
There are dogs that have laid down beside their dead master refusing to leave and starved to death, so there’s more going on than merely a food source. If you’d ever experienced that bond between yourself and a good dog, you’d know this. Yes, most are very food-motivated just as people are. I strongly suspect my dog would still be by my side if I ran out of food whereas just about all my friends and family, excluding my mother and two best friends, would be long gone.
I’ve fed a lot of humans who came back to bite me.
Stop feeding them and see how long that lasts.
