Hi micheal s:
I suggest contacting the company and ask them specific questions about their product.
My guess is, unless your dog has a health issue, protein is not the reason for the recommended feeding guidelines. When feeding treats you are adding extra calories and risk unbalancing their diet. Treats should not exceed 10% of your dog’s daily calories. At least that would be my concern with feeding treats or other unbalanced extras regardless of age. Here’s a little more info:
