What kind of dog food do you feed? I am looking for a new food, and realize I will probably need two as we have a 6 month old puppy and a 2 year old overweight pug. They are both on Hills Ideal Balance currently. The pug does fine but would like something more for weight loss, the puppy is a scrawny little thing. He isnt skinny but is getting almost a cup a feeding (2x) and is shinny but skinny and has gas that could kill a person. Not sure at exact weight but at 4 months at his vet appointment he was 12 pounds. The pug is about 26 pounds. Prefer grain free.
