We do not have a Costco for hours. I have fed Exceed for years. Thought they were going out but just changed bag. So for a time I went to the Diamond Natural chicken. First two bags okay but then dogs were loosing weight, coats turned awful. And still working on getting over that. But realize Exceed was right there to pick up, went back to it. So I say EXCEED for sure. I had also tryed PP a year or so back and just did not get anything special. Costly for the results.
We have fed Diamond Naturals Chicken & Rice, as well as Extreme Athlete for many years. Happy to answer or discuss questions with anyone. Please email.
