ownerof3dogs,

If Zeus is BC, you have one of the most high energy type
dogs there is. That can be a good thing ot not depending
on what his daily life is like. I think that breed needs to have
a "job", needs to being doing something almost all the time.

Have you ever looked up the symptoms on a dog behavior
type website? Gosh, there are tons of them & you can believe
what they say or not, at least it might help you get a different
slant on what his problem might be. Our instructor at puppy
class said that lip licking was a sign of nervousness. ?
He's a very good looking dog. Do you have any other pics?
