I have switched Rupert to a salmon based weight loss dog kibble called Performatrin Ultra that is also made with natural ingredients. He's lost 8 pounds since August and I haven't changed his treats or the canned food he gets mixed in. I mix in about 1/8 of a cup of the Chicken and Rice stew natural blend of the same brand name. I did a lot of research and found this brand to be better than all of the well known high end names for fat and carb content. It's cheaper and they don't need as much - but they feel fuller. Rupert is shiny, health and trim!
It's a brand made for the Pet Value stores - I checked and they are in NJ. Check for locations at their website:

They suggest you call the specific location to see if they have the product you want.
