Our Multivitamins for Dogs Review at a Glance

Do Dogs Need Vitamins?

Do Dogs Need Vitamins

Yes, dogs need vitamins as these nutrients are critical for their overall health and wellbeing. However, not all dogs need vitamin supplements. In general, healthy dogs eating high-quality diets get all the necessary vitamins through the food. On the other hand, dogs eating low-quality foods, dogs with vitamin deficiencies, and dogs with certain medical conditions benefit from vitamin supplementation. 

Can I Give My Dog Daily Vitamins?

Yes, you can give your dog daily vitamins. However, before you start using vitamins, talk to your trusted veterinarian. Some vitamin products should be used for a limited timeframe and then paused. Also, your dog’s health profile is a factor that needs to be considered when determining the length of the vitamin supplementation. 

What are the Best Vitamins for Dogs?

Dogs need several vitamins for normal functioning, optimal health, and peak condition. Here are the best vitamins for dogs. 

Vitamin A for Dogs. Perhaps the most popular health benefit of vitamin A is eye health (strong and potent eyesight). Other benefits include reproductive health, normal fetal development, growth support, and boosted immune system and cellular function. 

B Vitamins for Dogs. Vitamins from the B-complex have versatile functions, and together they affect every aspect of the dog’s health. Here are the most essential B vitamins and their roles:

  • Vitamin B1 (thiamine) is critical for the nervous system and proper carbohydrate metabolism
  • Vitamin B2 (riboflavin) helps break down and metabolize fats, proteins, and carbohydrates 
  • Vitamin B5 (pantothenic acid) modulates the energy metabolism 
  • Vitamin B6 (pyridoxine) regulates red blood cells production, hormone levels, and nervous system function
  • Vitamin B12 (cobalamin) helps metabolize carbohydrates and supports normal DNA formation. 

Vitamin C for Dogs. Also known as ascorbic acid, this vitamin has several roles, from cellular and tissue regeneration to boosting the immune system to maintaining skin elasticity. Vitamin C has antioxidant and anti-inflammatory features and helps prevent cognitive aging. 

Vitamin D3 for Dogs. This vitamin’s main role is managing the metabolism of calcium and phosphorus. Both minerals are vital for supporting normal bone and muscle formation and maintenance. Vitamin D is also known as the “sunshine vitamin.”

Vitamin E for Dogs. This fat-soluble vitamin is essential for cellular health and adequate fat metabolism. Plus, vitamin E has strong antioxidant properties, thus protecting the dog’s body from oxidative damage. 

When to Use Multivitamins for Your Dog

Basically, there are three situations in which dogs would benefit from multivitamin supplementation:

  • Dogs with vitamin deficiencies
  • Dogs with certain medical issues and conditions
  • Dogs at different life stages (puppies, lactating dogs, seniors). 

If you are not sure whether your dog needs supplementation, talk to your trusted veterinarian. Never start administering vitamins to your dog before consulting with your vet. Also, make sure you let the vet know if your dog is receiving some other medications or supplements. 

Risks Associated With Giving a Dog Multivitamins

As organic compounds, vitamins are vital for life. However, if present in excess amounts, they can cause issues. For example, too much vitamin A causes a condition known as vitamin A toxicosis. In other words, over-supplementing your dog is dangerous. 

Another risk associated with vitamin products stems from the added ingredients. More often than not, multivitamin products contain herbs that can interact with certain prescription and over-the-counter medications. 

What Vitamins are Bad for Dogs?

Human vitamins are absolutely bad for dogs. First, human vitamins contain high doses and can even cause vitamin toxicosis in dogs. Second, they often contain added ingredients that are potentially dangerous to dogs. Therefore, you must never share your vitamin or multivitamin product with your dog.

How to Choose the Best Multivitamin for Your Dog

Choosing the right vitamin supplement for your dog can be tricky, especially if you do not know what to look for. To help you narrow the list of choices, consider the following factors. 

Number of Vitamins. Some products feature one or two vitamins, while others a blend of vitamins for a more potent health-boosting effect. Which type is best for your dog depends on its unique needs. Talk to the vet if you are not sure. 

Added Nutrients. In addition to vitamins, many products feature added ingredients like minerals, probiotics, digestive enzymes, fatty acids, amino acids, and antioxidants. The more nutrients the product has, the more benefits it yields to the dog’s body. 

Supplement Form and Flavor. Vitamins for dogs come in different forms like soft chews, tablets, powders, and liquids. They are also available in an array of dog-friendly flavors. Always go for the form and flavor you and your dog like most. 

Reputable Brand. Always go for a proven brand with lots of positive reviews. Trustworthy brands will be transparent and often commission clinical studies of their products. Also, check the lot number on the product as this proves the brand performs quality control checks. 

Natural Ways to Include More Vitamins in Your Dog’s Diet

Here is a list of the vitamin-rich and dog-friendly fruits and vegetables:

  • Apples
  • Berries
  • Bananas
  • Mangoes
  • Kiwis
