Razzle is 6.5 lbs and gets 1/2 c a day. He is fed home made, with some large kibbles for teeth health - also one bone weekly, water additives, and teeth brushing
Now it is important to note he is not neutered and full males tend to maintain a higher metabolism.
He gets at least 30 minutes a day on walks, another 30 minutes with training and games, and will play (supervised) with our puppy. On big exercise days I will bump his food as much as 1/3 cup more. He is naturally an active boy, loving to run around the home etc.
