The domestication of dogs from wolves was a result of artificial selection. Humans purposefully bred the wolves that were less standoffish and less hostile toward humanity until they ended up with modern dogs. If this were possible with Grimm, it would require that evolution works the same way with them. If they truly are creatures without souls, it's possible that they have some kind of magical origin, and may not obey the same natural laws.
