I think you’re mistaking slight natural adaption for domestication, and taking domestication for granted. Go into nature and try and train a wild wolf. Good luck! You can’t.

Domestication, in the way that we see having happened with dogs (and cattle, and chickens) takes a really long time.

We consider cats “domesticated” and yet demonstrably they are not. If they were much bigger, they’d eat us, and if set into wild, nearly all household cats immediately revert to feral.

I owned five ferrets once. Loved them so much, but came to the realization that there are animals that should be pets and animals that maybe shouldn’t (yet). I think we have many, many more generations before raccoons are at the same level as dogs.
