Hi Tracey-
I just looked at the Nutrisource website. It states that the grain free chicken has 477 calories a cup. Also that it has 18% fat and 28% protein. I think it has higher calories than the average kibble. But two cups still doesn’t seem like it should cause weight gain for a large dog. Are you or someone in the household feeding extra treats? I feed my two lab mixes grain free Victor. It has about 400 calories a cup. The protein is 33% and the fat is 16%. Maybe this could be an option for you?
