Orijen is the best (imo) Check Chewy.com. I would add a topper such as scrambled egg, lean cooked chopped chicken breast, broiled chopped chicken liver, a spoonful of tuna, cooked lean meat, etc. instead of the canned food and add a splash of warm water prior to serving.
Store the Orijen in the freezer or fridg as it has no preservatives. Nutrisca is good as a base too.

Dr Google is not always accurate. Another thing, some dogs are just naturally lean. I have a 10 pound dog that eats as much as my 20 pound dog, they are both healthy, active and fit.
