I have an issue with our 8-month-old basset dog; when I try to do something he doesn't like, such as not letting him lick his wound after surgery or carrying him up and down stairs, whipping his feet, etc., he gets aggressive. It started out as a few playful bites to show me he didn't enjoy it, but now I'm actually terrified of him. "The weakest chain of the family," said a family member who considers himself a dog expert. I'm at a loss as to how to change this behaviour. He doesn't appear to have an issue with any other member of my family, therefore I'm worried the issue is with me. I like our basset and don't mind a few scratches... but every time he snaps at me, my heart breaks.
