Pigs are absolutely excellent companion animals in the same way, it’s well documented. My farmer friend has one for years and he was delightful. She had chickens who had wonderful funny personalities. There’s videos of cows playing with children and sleeping in their laps.
The logic just doesn’t make any sense. I see what you are saying, don’t get me wrong, but I just don’t get how people can “rescue” dogs and yet talk about how much they love bacon.
