Question: My friend's parents' dog just had puppies. She's usually people-friendly and non-aggressive. Recently though, she has bitten several family members belonging to the owners and we believe she is just overprotective of her puppies. This dog also lives outside in the yard. She has been very friendly towards me today though (won't let me handle the puppies but was more than willing to let me pet her and love on her and she was very excitable.) But she licked my hands and I forgot to wash them afterwards, and I aye a sandwich. The dog, I know for sure, is unvaccinated and has never been to a vet. Is it possible for me to contract rabies or some other transmittable disease? Rabies is the one I'm most concerned about. Aside from the aggression, I didn't see any other unusual signs in her though.
