Jeff is a 3 or 4 year old 44# Chow mix who is, as our trainer says, 'a genius.' If you want to do agility or love working with dogs, this is your boy. He is good with other dogs (except small ones - he does have a prey drive) and people. He's a great watch dog and cuddler. Owner needs to rehome only because of a change in work schedule. Neutered, up to date on shots and in perfect health.
