FAQs About Dog Supplements and Vitamins

This really depends on the needs of your pet. Consult your veterinarian on whether or not your dog needs extra vitamins in their diet. Often, your pet gets the correct amount of vitamins and minerals through their dog food. However, your vet may recommend additional supplements if they suspect your dog is deficient, if you make homemade dog food for your pet or just to support their long-term health and wellness. They may also prescribe veterinary diet dog food if deemed necessary.

When it comes to determining your pet’s unique needs, their size, age, breed and health history are very important. A DNA and health condition testing kit may provide valuable insight. Once you get the information, you can work with your vet to make sure your pet is getting the nutrients they need. And once you know which supplements are appropriate for your pup, pick the form your dog will take easily, like a flavored chew or powder that can be mixed in their food. Supplements that look and taste like dog treats and chews may be particularly easy to administer.

Protecting your dog’s joints is vital for their longevity and mobility. Look for solutions containing glucosamine and chondroitin—these two ingredients are the powerhouses of joint care. They have anti-inflammatory properties to help reduce pain and swelling, and they can increase cell turnover in your pet’s cartilage. Many of the best-selling dog supplements listed above include dog supplements for joint health.
