When choosing a new dog food for your dog, it’s important to consult with your veterinarian as well as your dog. Talk to the former about any special needs your dog may have, and monitor the latter once you switch. While your dog can’t tell you how he’s feeling, check to see if any behavior changes, like more panting, itching, or scratching. Also, make sure that bowel movements are still timely and regular. If your dog doesn’t have any dietary restrictions, Victor offers formulas in the Classic line that cater to all sizes and ages.
