When I got Baron he was on Purina puppy food. He seemed to always use gas. I tried several kinds, but the Royal Canin is what he's done best on. My other dog loves it too. No more gas and loose bowels. I really like the dog food, They're happy and healthly on it. Also, I LOVE Prison Break, I just got done watching the season premier. I Loved it. Boy I missed that show!!! Wentworth Miller is SOO hot... We should start a new group!!! The Prison Break Yorkie Mamas, LOL Take-Care,
