You can find tons of dog vitamins at pet pharmacies. With so many options, you may feel a bit overwhelmed by their claims and promises. Why does it sound like they’re all the same? And does your dog really need vitamins? Most importantly, are there any health risks involved? 

If you’re asking these questions, read all the answers below. We hope you’ll make the right decision for your dog’s needs. 


Good vitamins for dogs are hard to find. Still, if you follow a strict set of criteria, it’s not rocket science. Here’s what we rely on:

Active & Inactive Ingredients

Active ingredients have a high nutritional value. The most common ones we found in the supplements include:

  • Omega fatty acids
  • Vitamin C, D, A, E, K
  • B-Complex

Other beneficial ingredients worth mentioning are:

  • Amino acids
  • Glucosamine
  • Chondroitin
  • Calcium
  • Phosphorus
  • Magnesium
  • Iron
  • Zinc

So these are the substances you need to look for if you want to find the best supplements for your pet. 

Stamp of Approval 

We were thrilled to discover many brands with the NASC seal of approval. It’s a guarantee that these products are safe, effective, and of excellent quality. Some use vet-approved formulas, while others have FDA-approved facilities. All of the selected daily vitamins for dogs are made in the US with locally or globally sourced ingredients.

Satisfaction Guarantee

It assures you that the company will refund your money if you or your pooch dislike the formula. Note that not every item comes with a satisfaction guarantee. Still, you’re sure to find it in those of the highest quality. 

Size & Dosage

You can give most supplements once or twice a day. Companies usually put around 60 to 90 chews per package and up to 130 capsules. The package size of the powder supplements varies, but they typically last for around 60 to 90 days. 


Most of the vitamin and mineral supplements for dogs taste like chicken or turkey. Others take a more vegan approach, using herbal or vegetable tastes. We even found a cranberry-flavored vitamin. Still, not every supplement mentions what it tastes like, and it’s an important factor to consider, especially if you have a picky eater.

Customer Opinions

We searched and caught some good deals and best sellers. But the customers’ uncensored truth revealed what some supplements were really about. You can read all the opinions in our dog vitamin reviews.

Buyer’s guide

You shouldn’t take shopping for supplements lightly. Your pooch’s life depends on your decision. That’s why we’ve prepared a detailed guide you can follow.

What to Look For When You Buy Pet Vitamins? 

There are seven factors to consider when shopping for vitamins for pets. Take notes as you’ll need them for future reference.

Vet Advice 

You should first discuss everything pet-related with your veterinarian. Don’t get fooled by the vet-recommended products on the market. Even the most natural compounds may be harmful to your pet.


You have to choose between four types of vitamins — chews, capsules, liquid, and powder. Chews are ideal for pets that adore treats. Capsules may be challenging to swallow, but you can sprinkle their contents on meals, just like the powder. Liquid vitamins are the easiest to feed and mix.

Life Stage 

How old is your dog? Does it need senior or puppy vitamins? Choose depending on your pet’s needs. Some formulas nurture health conditions for a specific life stage, while others take care of the overall wellbeing of your dog.

Breed & Health Condition

Many breeds are prone to or suffer from chronic health conditions. Find formulas that’re specifically made to treat your dog’s needs. For example, supplements rich in omega fatty acids will nourish your dog’s skin and rejuvenate its coat.


Sometimes taste is a deciding factor. Make sure to choose a supplement with an enticing aroma and delectable flavor. If your dog doesn’t enjoy meaty flavors, you can try herbal, veggie, or even fruity dietary supplements for dogs.


Vitamins for your dog can quickly get expensive. Consider how much you would spend monthly and always seek a cheaper alternative without sacrificing the quality. Also, remember that a high price doesn’t necessarily mean optimal nutrition.

Vitamins & Supplements — What Are They and How Do They Work? 

Pets need pet vitamins and supplements to grow and develop into their best self. And whenever their meal lacks nutrition, pet parents boost it with powerful supplements. 

What’s more, many dogs suffer from numerous diseases, aches, and inflammations, so food isn’t always the issue. Still, vitamins can help with everything from bad joints and inflamed skin to problematic digestion and unhealthy brain function.

Some supplements are crafted to help a particular problem, like the joint health supplements for dogs, while others combine several superpowers in one formula. It’s up to you and your veterinarian to determine the right dog vitamins. 

Water-Soluble vs. Fat-Soluble Vitamins 

Vitamins are complex organic compounds that sustain life. We divide them into two groups:

  • Water-soluble: Vitamin B-Complex and Vitamin C
  • Fat-soluble: Vitamin A, D, E, and K

Water-soluble vitamins are as quickly digested as they are released. You must switch them regularly to affect the body.

Fat-soluble vitamins are kept in the liver and fatty tissues. Because the kidneys don’t remove them, they’re excreted considerably slower.  

You or your pet can accumulate a hazardous quantity of fat-soluble vitamins over time as they’re more toxic than the water-soluble ones. So it’s better to take them in tiny amounts. 

Dogs need vitamins for overall growth and development. Some of the essential ones include: 

Vitamin A — It’s excellent for dogs’ eyesight. The vitamin supports cell and immunological function, fetal development, and general growth. The recommended dosage is around 22272 IU. 

Vitamin B1 — Maintains the neurological system while also managing metabolism and appetite. You should feed your dog 0.56 mg of it per pound each day.

Vitamin B2 — Promotes healthy eyesight and is responsible for your dog’s cardiovascular function. Your dog needs at least 1,3 mg of vitamin B2 daily.

Vitamin B3 — The best pet vitamins contain B3 for proper energy production, healthy nerves, and skin. You should feed your dog 4 mg per pound daily. 

Vitamin B5 — Regulates hormone production and food metabolism. The recommended dosage is at least 4 mg per day.

Vitamin B6 — It helps the body to produce insulin, hemoglobin, and red blood cells. Your dog should get 0.4mg of pyridoxine.

Vitamin B7 — Famous for facilitating digestion. It breaks down proteins, fats, and carbohydrates. You can feed your dog 0.001 mg of vitamin B7. 

Vitamin B12 — Promotes RNA and DNA material construction, builds red blood cells, and manages the nervous system. Usually, dogs require 0.00025 mg per pound daily.

Vitamin C — Canine vitamins containing it helps collagen production. That’s an essential tissue that secures the body’s ligaments, tendons, organs, muscles, and bones. 

Folic Acid — The vitamin plays a crucial part in red blood cell growth. Also, it can protect cardiovascular health. Dogs need around 68 micrograms daily.

Vitamin D — The “Sunshine vitamin” facilitates the right balance of phosphorus and calcium. Dogs need it to have healthy muscles and bones.

Vitamin K — The dog’s body absorbs vitamin K via bacteria in the intestine and through food. Such doggie vitamins help in the clotting process and promote bone and health development. 

Vitamin E — It builds the dog’s resistance against oxidative damage. Your pet needs vitamin E for cell function and metabolism. The recommended dosage is around 8 mg daily. 

Choline — It plays a prominent role in supporting phospholipid cell membrane. Choline promotes brain function and a healthy liver. Also, it’s regularly used to treat pets with epilepsy. 

All in all, you should match these vitamins with your dog’s diet. If you need more clarification on how to do that, don’t hesitate to contact your vet.

Natural Sources of Vitamins for Dogs

You can add some foods to your dog’s diet for a positive impact on their health. Here are the best ones: 

  • Carrots — They help for healthy digestion, eyesight, skin, and coat. Also, they’re excellent energy boosters and take care of dogs’ teeth.
  • Spinach — As an anti-inflammatory food, spinach is good for the eyes and supports healthy bones. It fights cancer and provides high energy levels.
  • Sweet potatoes — They’re low in calories and ideal for healthy digestion. Sweet potatoes can help fight heart disease and cancer. They maintain healthy skin and coats and have anti-inflammatory properties.
  • Eggs — They provide the optimal vitamins for dog skin and coat. Also, eggs are perfect for maintaining strong and healthy teeth and bones.
  • Fish oil — Fish oil is famous as the “protector of the heart.” The oil can prevent kidney disease and soothe arthritis pain. Also, it relieves itching and inflammation. On top of that, it improves the nerves and cognitive functions.
  • Green beans — Ideal for healthy production of red blood cells. Green beans also strengthen the bones and boost dogs’ immunity.
  • Zucchini — It can help build strong muscles, bones, and healthy nerves. It’s also excellent for your dog’s eyesight and overall immunity.
  • Kale — Ideal for maintaining a healthy heart and bones. It prevents infections and helps the liver.
  • Chia seeds — They regulate blood sugar and slow down digestion. Another superpower of these natural dog vitamins is they help maintain healthy glucose levels. This works super well with non-prescription diabetic pup food.
  • Pumpkin — The vegetable can fight gut bacteria and keep healthy blood pressure. It boosts metabolism and healthy eyesight. Plus, it strengthens bones and takes care of the skin, coat, and dogs’ overall immunity.
  • Blueberries — Apart from being delicious, blueberries help the heart and regulate a dog’s digestion. They also promote a healthy weight, protect the cells, and strengthen the bones.
  • Apples — Excellent for fighting diseases, cleaning the dogs’ teeth, and refreshing the breath. Also, apples improve gastric health and aid joint problems.

Chat with your veterinarian about your custom recipe of natural dog vitamins and minerals. Remember, even though these natural foods are full of nutrition, you must still add them to your dog’s diet in moderation. 


Now that we know which vitamins are essential for dogs’ health and where to get them naturally, it’s time to find out what supplement type to choose.

  • Treats / Chews — They’re usually quite calorie-dense, so veterinarians recommend giving them in minimal amounts — 10% of a dog’s daily calories. Good dog treats are all-natural, organic, protein-rich, and filled with minerals and vitamins. 
  • Tablets / Capsules — These are chewable dog vitamins with a soft texture. You’ll commonly find vitamins and fatty acids from natural oils in these capsules. You can give them to your dog as they are or sprinkle them on top of a meal.
  • Liquid — They’re usually rich in omega fatty acids and ideal for maintaining a healthy coat, skin, and joints. You can add them to dry kibble or wet food. 
  • Powder — It’s a vitamin boost you can mix into any meal. The vitamin powder for dogs can help treat many health problems, including sensitive stomachs or inflamed joints.

What Dogs Need Vitamins the Most?

Some dogs need more nourishment than others. For instance, dogs with vitamin deficiencies don’t consume enough dog food, or the one they get is low in nutrition. The main symptoms of poor nutrition include:

  • Bad breath
  • Weight loss
  • Inconsistent stool
  • Excessive shedding
  • Dandruff
  • Allergic reactions and infections
  • Dull Coat

In most cases, pet supplements come in handy for senior dogs. Old age comes with various health issues, including memory loss, impaired vision, weak muscles, and arthritic pain. And supplements are full of proteins, fatty acids, and minerals ideal for seniors’ wellbeing. 

Pregnant dogs must eat for two, so they need a nutritional boost. Remember to increase the portions around week five of the pregnancy progressively. After giving birth, the mother would need around 2–4 more calories than other dogs. 

You should also be careful with homemade or vegan dog food. Even though the ingredients are fresh and free of chemical preservatives, they may be nutritionally deficient. So always check with your veterinarian so that they can advise you on the best dog vitamins to supplement your fresh dog meals.

Sometimes, even the most nutritional dog food may not be enough to help your pet. That’s where vitamins for dogs come into play. Whether it’s for a chronic disease or a quick immune boost, they can help your dog in a variety of ways, including: 

  • Complimenting meal nutrition
  • Improving your dog’s immune system
  • Increasing the intake of vital chemicals
  • Reducing itchy, inflamed skin, or fur loss
  • Decreasing the chances of diarrhea and gastrointestinal issues
  • Easing recovery
  • Slowing down cognitive aging

Cons of Doggy Vitamins

Vitamins for dogs can be tricky. For instance, too much calcium can lead to bone issues. Here’s what else you should know:

  1. Regulation Issues — There are hundreds of supplements on the market, and the FDA has limited control over them. As a result, dietary supplements’ safety, efficacy, and quality are all subject to debate.
  2. Rapid Growth & Skeletal Abnormalities — Excess calcium, mineral, and vitamin D can cause orthopedic illness (DOD). That’s especially prevalent in large and giant breeds, like Golden Retrievers and Saint Bernards.
  3. Vitamin Overdose — Toxicities can occur if your dog consumes dog vitamins in high quantities. For instance, a Vitamin A overdose can lead to fatigue and vomiting, while too much Vitamin D can make your dog drool, lose weight, and have weak muscles. 

In the end, vitamins and minerals are beneficial to your dog’s health, but your pet might not need them if they’re in good shape. It all comes down to food. We urge you not to squander your money if your dog is happy, healthy, and energetic. Go for a limited ingredient dog food, and if your dog has a health problem, see your veterinarian before adding any supplements.

What vitamins are harmful to dogs?

If given frequently and in larger amounts, the most harmful dog vitamins include xylitol, vitamin D, calcium, and iron. Although they don’t do any harm in smaller amounts, you should be aware of them. 

Can my dog take over-the-counter vitamins?

Always, and we repeat, always consult your veterinarian about a vitamin, supplement, dog food, or homemade recipe before giving it to your pet. Never feed it over-the-counter vitamins. 

Can my dog take human vitamins?

The safest human vitamins you can give your pooch are the water-soluble ones, such as vitamin C and B-Complex. They’re stored in the body in small amounts and can benefit dogs. Still, your vet should approve the dog vitamins, so never give them without checking with them first.
