I love this phrasing, as I think it sums up the difference between dogs and other animals with regards to human communication. It's possible to communicate with other animals if you put in the effort, but dogs on the other hand are often willing to put in the effort to communicate with you!
Some people have even in this universe, but not so many, because they are not easy to handle. And back then having pets, was not so much a hobby - but the dogs were useful for survival. (guarding and hunting)
Bears not so much and therefore much harder to control. Same with cats, which is why they have been kept around to hunt the mice and rats - but only small cats.
Also I believe the first dogs did not came from wolves, but other wild dog breeds.
