We're picking up Charlie, the wirehaired pointing griffon, soon. Right now the breeder is feeding him Kirkland which is a great food, but I was wondering if it would be appropriate to switch him to TOTW. Strider eats TOTW high prairie and it would be convenient if they could eat the same formula. Here's the fat and protein breakdown: Guaranteed Analysis Crude Protein 32.0% Minimum Crude Fat 18.0 Minimum Charlie is a little over 4 months old. Would this food be too rich for him/make him grow too fast? We'll ask his breeder too, but I wanted to also have your guys' opinions on it.
