As a dog owner, you want the best for your fur baby. You make sure they get enough exercise, feed them properly, and take them to the vet for regular check-ups. But have you ever considered adding vitamins to your dog's diet?

Just like humans, dogs also need certain nutrients to stay healthy. However, not all dog foods provide enough of these essential nutrients.

Nutritional supplements can help fill in the gaps and provide additional health benefits. Adding vitamins to your dog's diet may also help with a variety of health issues, from boosting their immune system to nourishing their coat and skin.

Read below to explore the benefits of different vitamins for dogs and what they can help with.


What Can Vitamins for Dogs Help With?

Vitamins and minerals support bodily health in numerous ways from helping build strong bones, keeping skin healthy, protecting against oxidative stress, and aiding in digestion. Like humans, dogs also deal with certain health struggles, some of which may be attributed to nutrient deficiency. 

For example, a lack of calcium in dogs can lead to symptoms such as seizures, loss of appetite, and weakness. Other symptoms of nutrient deficiencies include dull coat, lethargy, mental confusion, and more. 

Though not every health issue in your dog may be caused by nutrient deficiency, ensuring your pup receives adequate nutrients will benefit their overall health so they can be the best and healthiest version of themselves. 


Which Vitamins Should You Give Your Dog?

Your dog should be getting most of their nutrients from their diet, but supplementing with key vitamins and minerals can be beneficial for ensuring they are in optimal health. 

Which vitamin supplements you give to your dog may depend on their individual health needs. For example, if your dog suffers from arthritis, supplements that strengthen bones and joints could be beneficial for them. 

Below are examples of vitamins for dogs and what they do. 


Vitamin A

Vitamin A for dogs can have a variety of positive benefits, particularly relating to eye health. This fat-soluble vitamin is needed for fetal development as well as cell and immune system function, and it also helps ensure good vision.

Dogs' bodies can't create their own Vitamin A, so it must be taken in from food sources or dietary supplements. Fortunately, many common dog foods contain Vitamin A, such as beef liver, eggs, and certain kinds of fish.


Vitamins C and E

Vitamins C and E are both essential nutrients that act as antioxidants in your dog's body. Antioxidants are substances that fight free radicals and protect cells from oxidative damage, which is a risk factor for cancer. 

Antioxidants like vitamins C and E also help to slow down the aging process, improve memory and cognitive function and may help in reducing inflammation and the risk of heart disease. 


Vitamin D

Vitamin D is an important nutrient that supports a healthy immune system and calcium absorption to help maintain strong bones. Dogs do not form vitamin D after exposure to sunlight like humans do, so food or supplement sources are key.

There are a variety of foods that contain Vitamin D, including marine fish oil, fatty fish, egg yolks, dairy products, liver, beef, and cottage cheese. 


Biotin (Vitamin B7)

Biotin, also known as Vitamin B7, is a water-soluble vitamin that plays an important role in maintaining a healthy metabolism and overall good health. It can be found in many foods including eggs, almonds, bananas, mushrooms, and sweet potatoes.

For dogs, biotin has been shown to offer several health benefits. Biotin helps to promote strong bones in dogs by improving calcium absorption. It also helps maintain healthy skin and coat and can help improve your dog's overall energy levels.

As a bonus, biotin may also reduce inflammation in dogs.


Vitamin K

Vitamin K is an essential nutrient for dogs and is vital for their overall health. This fat-soluble vitamin helps promote clotting of the blood, which helps to prevent hemorrhaging, excessive bleeding, and uncontrollable bleeding.

Without Vitamin K, a dog could suffer fatal consequences due to an inability to produce clumps of protein-rich cells that block internal hemorrhages in the body. Furthermore, certain toxic rat and mouse poisons can cause Vitamin K deficiency in dogs by inhibiting their ability to use it.

Vitamin K-rich foods include liver, vegetable oils, spinach, and broccoli.



Iron is an important mineral all dogs need in their diet. It's essential for the production of hemoglobin, a protein that helps red blood cells carry oxygen to all parts of the body.

Iron also plays a role in energy metabolism and immune system function. When dogs don't get enough iron in their diet, they may become anemic due to a lack of red blood cells.

Symptoms of anemia in dogs include weakness, fatigue, and pale gums.



Glucosamine is a natural compound found in the cartilage of animals. It has been studied for its potential use in treating joint pain and degenerative arthritis, especially in dogs.

Glucosamine is believed to help support healthy joints by stimulating the body’s production of proteoglycans, which give cartilage its cushioning properties. It can also help with maintaining overall joint health. 


WoundVite for Dogs

Vitamins for Dogs: The Bottom Line 

Vitamins and minerals are essential nutrients that play a vital role in your dog's health. Ensuring that your pup is receiving the necessary vitamins from their diet, or by supplementing with vitamins for dogs if needed, can help to ensure that your pup lives a long and healthy life.

Before considering supplements for your dog, talk to your vet about which vitamin supplements are right for you.
