thats why you get 2 they exercise each other Just kidding... ours are real good but they are young we walk them daily plus they have a large yard. As for grooming I usually due it after 9 at nite. While watching tv. Very relaxing... once we are all settled for the nite. They can go very nutting when people come over... ours finally quite down after 5. OR a nice bone with peanut butter on it once they are done that the just come a lay down.
