Are you sure your Yorkie is fat and not just a bigger guy? Just because he's a large Yorkie doesn't necessarily mean he's overweight. I'd have to see a picture to tell.
However; I would suggest taking him OFF of Purina One. It's not really a good food at all. If you go into a store like Pet Valu or a holisitc pet store, mom & pop type store, they sell the better brands. I'd recommend Innova, Nature's Variety, Merrick's, Natural Balance, etc. |
