Diet/Nutrition for Pugs

Question
I have 3 pugs, each with different dietary needs. How and what are the best ways to accommodate each of their needs without going bonkers? I am looking for help in treats and what is best for them, other than their prescribed dog food.

Chango is on the Hill's c/d diet.

Smash is on the Hill's g/d

Answer
Hills is a terrible food no matter what the diet.
While I'm not thrilled with Royal Canin, it's certainly better than Hills. The Control formula would work for both dogs.
Here's one website that you might enjoy that has recipes if you choose to cook your own, which is BEST for dogs with your problems.

I much prefer Flint River Lamb and Rice Premium Wellness unless your dog had advanced kidney disease in which case I would cook for them myself.
