Legal Question in Real Estate Law in California

Although this question does have some real estate aspects, it is more of a dog-bite or pet question, and you might get better responses from rre-asking it under such a category if we have one. However, I'll take a stab at answering. The dog owner's commercial liability policy is likely to cover the vet bill. The property owner's potential liability seems somewhat remote because the dog's presence and potential viciousness was not something the property owner reasonably could have anticipated or controlled.
