I have been walking dogs for a while now and have just gotten paired up with a Cairn Terrier. Cutest little guy in the world. He is 7 months old and very smart. The only problem is he really likes to nip, especially at your nose! His owner just kind of blows it off as puppy behavior and doesn't do much about it. I can watch myself, but I see the little guy around others and it's kind of like watching an accident waiting to happen. What can I do to discourage him from this? I am with him 3 or 4 days a week about 1 hour each visit so I would have the time. And I do have the owners permission to work with him. I am trying distraction right now as he is very food motivated. Any other suggestions?
