Benny has always loved people, including strangers… We got him neutered about 7 months ago, and he was always afraid of the vet after that and tried to bite him when he examined him.
Recently (3-4 weeks or so) he's been agressive towards strangers and people he doesn't see often. He is fine with them until they reach down to pet him. He bit my neighbor and broke his skin. He bit my nephew and snapped at a few of my friends that he doesn't see often. He is okay with the family and seems okay with others until they try to pet him.
I am not sure what caused this recent negative behavior.
He hasn't been hurt by anyone, to my knowledge. He met a friend a few months ago (my sister's dog) who he plays with a couple times/week. He picked up a few negative behaviors from her (she would growl at him when he messed with her while she was sleeping, so he started doing it to her and then started growling at her for other things, but they never fought). I am wondering if he is applying this learned behavior and using it against humans?
We called a behavioral specialist, but I would appreciate any help/suggestions or a recoendation for a good behavioral specialist in NE Ohio. I want to be able to take him places without worrying about him biting someone and want to be able to trust him around my family.
