In looks, maybe if you squint? Lions are felines; bears are not canines. They are not related.

Coyotes and wolves are the wild equivalent, but they aren’t much bigger. I think the largest canines that exist today have been domesticated, like the Saint Bernard and the Great Dane. There are others, but those are the popular ones. Also, I think you could breed the wild out of coyotes and wolves if you tried. I’ve never heard of anyone keeping coyotes as pets, but wolves? Sure. Especially wolf cross-breeds with domesticated breeds.
