Two months ago we adopted a dog, bringing our total to three. The three dogs have worked out their hierarchy and all seem to acknowledge that I am the Alpha. Each dog has plenty of room to room to run and play, and each has his own den area. My problem, is that the new dog, called Blondie, spends a lot of time and energy going after my hands or wrists. Blondie is part terrier and part who-knows-what and the vet.'s guess is that he is about a year old. As far as we know, he has not been abused, he was just a little unlucky in the people who thought they wanted him. When he tries to get his mouth on me, he doesn't seem intent on inflicting harm, he just jumps for my wrist or hands when I am playing with the dogs, working in the garden, or when I have a bowl of food. He usually does this when he sees me after a long absence, such as when I get home from work, or first thing in the morning. I've tried blocking this pesky dog with my hip while telling him "no," but it doesn't seem to work. Any suggestions as to what this behavior means and how to STOP IT???
