Your morning routine includes popping a multivitamin, taking a biotin supplement for healthy skin and hair, and starting an elderberry syrup regimen at the first sign of the sniffles—and you feel great. So, if vitamins and supplements are a big part of your wellness regime, should you give them to your dog, too? For a lot of pet owners, the answer is a resounding YES. 

Pet owners spent a whopping $800 million on pet supplements in 2020 with vitamin supplements for joint health, heart health, skin and coat health, and digestive health topping the list as the most popular options.

What Vitamins are Good for Dogs?

Your dog needs several vitamins and nutrients to help them maintain good health. Vitamin A helps with vision, immune function and growth; vitamin D, calcium, and phosphorous support strong bones and muscles; vitamin E protects against cell damage; riboflavin and magnesium boosts enzyme function; and zinc helps metabolize protein and carbohydrates, according to The National Academies.

Without adequate vitamins and minerals in their diets, dogs could suffer from poor growth, muscle weakness, lethargy, diarrhea, loss of hair, skin lesions, convulsions, appetite loss, and a host of other health issues.

A complete and balanced diet provides all of the vitamins and minerals your dog needs for optimal health but supplements could be beneficial. 

Best Dog Vitamins: What to Look For

There are vitamins for older dogs, vitamins for small dogs, vitamins for pregnant dogs, and vitamins targeted for specific health and wellness benefits, which can make it hard to know which ones to choose.

Although the U.S. Food and Drug Administration doesn’t regulate vitamins and supplements formulated for pets, it doesn’t mean that there are no options to gauge the quality and purity of the supplements you purchase for your dog.

Look for the National Animal Supplement Council seal. The third-party certification verifies that vitamins were made with quality ingredients and manufactured under strict guidelines. The website also has a list of supplement recalls and is a good spot to check before making a purchase.

Capsules, pills, chews, liquids and other dog vitamin supplements evaluates supplements, including pet supplements, for quality ingredients and correct product labeling. It’s an independent, subscription-based site.

Your veterinarian is also a good source of information and can recommend quality dog vitamins that are specific to your pet’s needs.

Dog vitamins are sold as powders, liquids, pastes, and capsules. Powders, pastes, and liquids can be added to dog food (or another high-value food item) to mask the taste while pills might need to be tucked into pill pockets if your dog is reluctant to take her daily vitamins.

Dog Vitamins: Tips and Advice

Some vitamins—or ingredients—might not be safe for certain dogs, including pregnant or nursing dogs or dogs taking certain medications. It’s best to consult with your veterinarian for advice on the best dog vitamins. 

Remember: It’s essential to stick to vitamins made for dogs. Several vitamins and supplements manufactured for humans contain xylitol, an artificial sweetener that can be fatal for dogs. In fact, ASPCA Poison Control included it on its top 10 list of pet toxins.

Store supplements in a cool, dry location out of reach of pets.
