If your commercial dog food says it’s complete and balanced, then your dog should be getting all the vitamins, minerals, and nutrients he needs from his dog food. This means you do not need a dog multivitamin unless your vet has recommended one. Be sure to check the labels and ingredients on your dog food to ensure it’s complete and balanced. And to ensure he’s getting the appropriate levels for his age, always give your dog commercial dog food that’s life stage suitable — puppy, adult, or senior. He shouldn’t need any nutrient dog supplements unless your veterinarian recommends them.
However, if your dog is eating mainly homemade dog food or a vegan diet, he may not be getting everything he needs. You should consult with your veterinarian to develop a plan to supplement your dog’s homemade food diet. Your vet may recommend adding certain foods to your recipes or going with a dog multivitamin supplement.
Never give your dog human vitamin supplements. Dogs have very different nutritional needs than humans, and too much of specific vitamins can make dogs very ill. Suppose you’re considering giving your dog species-specific vitamins. In that case, it’s essential to contact your veterinarian to ensure your dog gets everything he needs without overdoing certain vitamins that he may already be getting in his diet.
Here are some top-rated multivitamins for puppies, adults, and senior dogs explicitly formulated for dogs. Be sure to read the label to determine the correct dosage amount for your pet (varies by size and weight).

Our Personal Experience
We had the opportunity to try out Rockwell Pets Pro in exchange for an honest review. The vitamin is in a liquid format which is easier to give our dog than chews since we can mix it with his food. Our 11-month-old puppy is using this product along with their probiotics sprinkled on top. The product is an orange color and relatively odorless. Georgie gobbles it up and has shown growth in size and weight with use (he was relatively lean before). Due to his small size, he doesn’t require a large dose. So, the bottle should last us a good 3-4 months, providing a great value. – Sadie C., Canine Journal
