Choosing the right food is one of the most important ways to keep your pet healthy, Claire, but because there are so many options, it can often be difficult to select the right food. We generally recommend a high-quality product formulated for your pet’s specific life stage and nutritional needs, rather than generic or store brands.
When feeding a high-quality pet food, a daily supplement generally is not needed. Over-supplementation can lead to health problems, so it’s important that you feed your pet vitamins and/or minerals only if your veterinarian suggests it. We would recommend discussing your dog's nutritional status with your vet to determine whether a supplement is needed.
