How can you help your hamster to lose weight?

They have dog food that's for over weight dogs at your local grocery store at the price of regular dog food also cut down or cut out treats and no human food

Carrots make good treats! Healthy and almost everybody has 'em in their fridge. Some dogs have stomach problems though. A little at first, and if they don't seem fishy then make them your regular treat. If you have a dog that likes toys, then use toys, not a treat.
