I agree with everything Naturella has recommended!!
Protein is actually ideal for weight loss. Here’s some great information in the Journal of Nutrition.
“High-Protein Low-Carbohydrate Diets Enhance Weight Loss in Dogs”

and
“Weight Loss in Obese Dogs: Evaluation of a High-Protein, Low-Carbohydrate Diet”
http://jn.nutrition.org/content/132/6/1685S.full
For what it’s worth, I’ve had nine toy and small breed dogs on diets with protein amounts ranging from 45 to 54% that are also relatively inactive and do not have weight issues. Like Naturella recommended, consider lowering the amounts fed or even switching to a higher protein, lower carb food.
