Yes, Carrie, Blondie gives a series of little mouthing nips, usually with just his front teeth. When he does this his tail is going fast and his ears are perked up. He is especially interested in getting my attention this way when I am interacting with one of the two other dogs. Affection???? That makes sense when I see all the dogs interact and how crucial biting, nipping, licking, etc. is in their communication. I will try your suggestions. I do love this little fellow, but YIKES! Enough already!
