i ride my bike and let my dog run next to me.. it took some training and a few brakes locking up because he stopped or ran across the front of the bike but hes got the hang of it
dogs REQUIRE exercise no matter what size
i have an 80 lb lab... he is loud, likes to jump but i used a company called bark busters and employed some of the technics they teach and its really helped a ton. but exercise is the key.
