Many dog owners go to great lengths to ensure their dog benefits from the best possible diet, veterinary care, and quality of life, and they are constantly seeking new ways to spoil and care for their pup. This often leads them to consider providing their pooch with a multivitamin.

But, do dogs need multivitamins? And if so, which ones are appropriate? We’ll examine these questions and others below.

Best Vitamins For Dogs: Key Takeaways

  • Just like humans and all other animals, dogs require vitamins to remain healthy. Fortunately, most dogs will get all the vitamins they require by eating a food that meets the AAFCO guidelines for their current life stage.
  • In some (relatively rare) cases, dogs can suffer from vitamin deficiencies, which necessitate the use of supplemental vitamins. Deficiencies can cause a variety of health problems, ranging from premature greying and other relatively minor issues, to more dangerous health problems, including things like poor cardiovascular function.
  • However, improper vitamin supplementation — particularly over supplementation — can be extremely dangerous for dogs. Accordingly, owners should only administer vitamin supplements when explicitly instructed to do so by a veterinary professional.
  • Our favorite pick for dog vitamins? The Finn Multivitamin – it features a scientifically-balanced blend that packs together vitamins, probiotics, and digestion aids for a true all-in-one canine chew!

What Are Vitamins, Exactly?

Vitamins are small organic molecules that the body uses to carry out various biological processes. Your dog’s body is unable to make most vitamins (there are a few exceptions), so they must be obtained via the diet (although some vitamins, such as Vitamin E, may also be absorbed through the skin).

Vitamins can be derived from a number of foods, but some of the best sources include fresh fruits, fresh vegetables, dairy products, and organ meats.


Most commercial dog foods are fortified with vitamins, but owners can also provide their dog with supplemental vitamins – much like those humans take.

Although a number of supplements are often thrown into the “vitamin” category, things like probiotics, glucosamine, chondroitin, fish oils, calcium, zinc and several other common supplements should not be considered vitamins.

These compounds play a number of beneficial roles in your dog’s body, and many – especially various minerals – are included in multivitamin supplements. However, these all represent different types of substances, which do not fit the definition of a vitamin.

What Kinds of Vitamins Does My Dog Need?

Vitamins are not all created equally, and they have a number of chemical differences.

Scientists recognize 13 different vitamins that are crucial for good health, and they name most of them after a letter (sometimes followed by a number). Each of these vitamins plays a different biological role, and your dog needs each in different amounts.

Vitamins are classified in two primary categories: water soluble and fat soluble. Because they are handled very different by the body, they are best explained separately.


Water Soluble Vitamins

Most of the vitamins your dog’s body needs are water soluble, meaning that they dissolve readily in water.

Because of this, these vitamins are not stored in the body in significant quantities. This means that they must be ingested on a daily basis to ensure their body has enough at any given time.

Our Source for Recommended Daily Vitamin Intake

All recommendations taken from the AAFCO’s Proposed Revisions Edited per Comments for 2014 Official Publication. All values are provided as milligram or international unit per kilogram of food consumed, assuming a caloric density of 4000 kcal ME/kg.  

The primary water-soluble vitamins include:

 Vitamin B1

Also called, thiamine, Vitamin B1 helps to promote proper nervous system function and is involved in appetite stimulation and the metabolism of food.

Weakness, loss of bodily control, and diminished appetite can all occur in dogs who do not obtain enough of this vitamin.

Dogs of all life stages need approximately 2.25 milligram of Vitamin B1 per kilogram of food consumed every day.

 Vitamin B2

More commonly called riboflavin, Vitamin B2 is very important for good vision and healthy eyes, and it also helps support the cardiovascular system. It also helps your dog’s body to produce niacin from the amino acid tryptophan.

Dogs of all life stages require 5.2 milligrams of riboflavin per kilogram of food consumed every day to avoid problems like poor vision or heart failure.

 Vitamin B3

Better known as niacin, Vitamin B3 is important for healthy skin, nerves and proper energy production. Dogs who fail to get enough Vitamin B3 may exhibit inflamed gums, bloody diarrhea or diminished appetite.

Dogs of all life stages require approximately 13.6 milligrams of B3 per kilogram of food consumed everyday. 

 Vitamin B5

Vitamin B5, or pantothenic acid, as it is sometimes called, is involved with food metabolism and hormone production. Dogs suffering from a Vitamin B5 deficiency may lose hair or exhibit premature graying.

Dogs of all life stages need approximately 12 milligrams of Vitamin B5 for each kilogram of food consumed each day.

 Vitamin B6

Vitamin B6 – also called pyridoxine – helps the body produce red blood cells, hemoglobin and insulin. Anemia often results from Vitamin B6 deficiencies, although some dogs may develop skin lesions if not provided enough of this crucial vitamin.

Dogs of all life stages require approximately 1.5 milligram of Vitamin B6 for each kilogram of food consumed each day. 

 Vitamin B7

Vitamin B7, also known as biotin, is very important for digestion, as it helps your dog’s body breakdown carbohydrates, fats and proteins. Intestinal disruptions are a common symptom of Vitamin B7 deficiency, as are dry skin and poor coat condition.

Your dog needs Vitamin B7, but the AAFCO has not established a recommended daily dosage for it. 

 Vitamin B12

Occasionally called cobalamin, Vitamin B12 helps to maintain the nervous system, produce red blood cells and assist in the construction of genetic material (DNA and RNA).

Despite being important to these crucial biological functions, dogs only need a minute amount of Vitamin B12 – about .028 milligrams per kilogram of food consumed (regardless of life stage) – each day.

 Folic Acid

Folic acid primarily plays a role in red blood cell formation, although it may also be associated with protecting cardiovascular health.

Dogs of any life stage who fail to get the required daily dose — 0.216 milligrams per kilogram of food consumed  – may develop anemia.

 Vitamin C

Vitamin C, which is sometimes called ascorbic acid, helps your dog’s body produce collagen, which is a connective tissue that helps to hold the body’s bones, muscles, organs, tendons and ligaments in place. It also plays roles in bone formation, the healing process and proper immune function.

Dogs produce their own Vitamin C, so you needn’t provide it to them.

Fat Soluble Vitamins

Fat soluble vitamins do not dissolve readily in water, and your dog’s body stores them in the liver and various fatty tissues. These types of vitamins stick around in your dog’s body for a long time, and, if given in excessive quantities, they may lead to health problems.

In fact, excessive levels of fat-soluble vitamins (particularly Vitamins A and D) are especially dangerous for growing dogs, once again highlighting the importance of working closely with your vet, rather than just providing supplemental vitamins in a haphazard fashion.

The primary fat-soluble vitamins include:

Vitamin A

Vitamin A – also called retinol – is important for a variety of biological processes. Some of the most noteworthy include bone growth, cell division, immune system regulation and gene expression.

Dogs of all life stages require about 5,000 International Units of Vitamin A per kilogram of food consumed per day. 

Because fat-soluble vitamins can lead to toxicity problems if given in excessive amounts, many multivitamins and supplements contain beta carotene, which is a Vitamin A precursor that the body converts as necessary, rather than retinol. This prevents your dog’s body from suffering from a toxic buildup of Vitamin A (retinol).

 Vitamin D

Vitamin D — especially the active form of the vitamin, known as Vitamin D3 – is heavily involved in the biochemical processes involving calcium and phosphorus, particularly the absorption of calcium from the small intestine. Vitamin D deficiency can result in rickets and poor tooth development.

Dogs of all life stages require about 500 IU of Vitamin D per kilogram of food consumed each day. 

 Vitamin E

Vitamin E, often called tocopherol, is an antioxidant that helps to protect blood cells and essential fatty acids. Vitamin E deficiencies can cause intestinal disease or reproductive failures.

Dogs of all life stages need about 50 IU of Vitamin E per kilogram of food consumed each day.

 Vitamin K

Vitamin K is obtained through a variety of food sources, but bacteria in the intestinal tract also produce it as well. Vitamin K is involved in the blood-clotting process, and it is responsible for helping to promote proper bone health and development. Dogs who suffer Vitamin K deficiencies may suffer from internal bleeding or altered clotting times.

The AAFCO has not established a daily recommendation for Vitamin K in dogs. 

What Dogs Require Vitamin Supplements?

Most dogs satisfy their daily vitamin requirements by simply consuming a high-quality dog food that is properly fortified. However, there are some dogs who may require a supplemental vitamin.

Dogs Fed Homecooked Meals

Homecooked meals can be a great option for owners with the time and desire to tackle the task, but most homecooked meals are likely deficient in several key vitamins. Accordingly, multivitamins may be appropriate for these dogs.

 Dog Suffering from Specific Vitamin Deficiencies

Your veterinarian may indicate that your dog is suffering from a vitamin deficiency, which can be treated by the administration of a vitamin supplement. Some vets may recommend taking a multivitamin to address these needs, while others may prefer administering a single-vitamin formula.

 Dogs Suffering from Specific Health Problems

Some health problems, such as rickets, can be treated with supplemental vitamins. In such cases, your vet will likely recommend administering a single-vitamin formulation.

Consult your veterinarian if you believe your dog may be benefit from a multivitamin or if you are concerned that your dog is suffering from a deficiency. Vitamins are important for your dog’s health, but excessive levels of some can be dangerous and excessive levels of others are simply wasteful.

I have used the petjoy multi vitamins soft chew and my dogs love them, also I saw a big different in them in one weeks time. One of my dogs that is 13 yrs old has never done anything in her life except eat and sleep. She would never play but she dose love being in your lap. Now she acts like she has more life in her plus she even started dancing when its time to eat plus she will bark at you when she wants something. It’s just amazing the different in how she acts, wish I had found these years ago. My other dog that is 13 yrs old also show signs of being more alert and happier and wants to play. I can’t see buying anything else when I know what this has done for them.


You should never, ever give your pets folic acid, fake vitamin C etc. Folate is different from folic acid, which is basically poison.

Ben Team

That’s just not true, Joseph.
Folic acid is simply a synthetic form of folate (Vitamin B9). In fact, folic acid supplementation is necessary for treating some health problems in dogs.
I’m not sure what you’re referencing about the “fake Vitamin C.” As we mentioned, you don’t even need to worry about Vitamin C for your pupper, as his body makes it naturally.


I feed a raw diet, which is wet. How do I adjust the amounts listed for each supplement. Do you know the dosages according to a dogs weight? That might make more sense. Thanks


Focus on the correct dosing of fat soluble vitamins; A, E, D …., tailored to the animals weight. The water soluble vitamins, B1, B2, B3 … will not accumulate over time like the fat soluble vitamins so a little extra will not be a problem and do not forget the minerals. Learn your animals needs; dose mg/lb or kg. Keep reading!
