Many people take vitamins and supplements to support a healthy lifestyle and diet. When you’re not getting the nutrients you need from food, vitamins are a great place to turn to. Fortunately, there are not vitamins and supplements for dogs too! If your pup isn’t getting all of the crucial vitamins from their daily kibble, it may be time to throw a multivitamin into the mix. Of course, just like anything else, you should always consult your doctor before adding any additional supplements into your dog’s diet. If your pup already gets a healthy dose of vitamins and minerals from their diet, overdoing it can cause unwanted side effects as well. We’re compiling a list of some of the best vitamins for dogs, to help you find out if your dog has any vitamin deficiencies, and the best way to help them achieve their healthiest form!

important vitamins for dogs

friendly dog

There are a few crucial vitamins that can make a big difference in the way your dog feels. If your pup can’t get these vitamins from their regular diets, adding in an additional supplement can do a whole world of good for them. Vitamins can keep your dog’s coat looking great, improve their joint function, and more. Check out some of the most important vitamins and minerals for your dog below, and consider (with your doctor’s help) whether your dog may need an additional supplement. Some of the most important for dogs are Omega fatty acids, Glucosamine, Chondroitin and Vitamins A, C, and E. 

We often find that dogs with sensitive stomachs don’t get the necessary nutrients to support their active lifestyles. Dogs that are on special diets don’t always have the ability to eat nutrient rich foods and treats. Supplements and vitamins are typically easy on the stomach, and have all the health benefits you wish you could get out of your dog’s food.

Unfortunately, all of the vitamins you think you’re getting from your dog’s regular kibble, aren’t actually in their food at the time of consumption. Nutrition facts are based on the nutrients in the dog food while they’re being packaged in the factories. Nutrients will be lost due to oxidation, so when your pup finally gets their paws on the kibble, it won’t hold as many nutrients as you see listed on the bag.

Omega Fatty Acids

Omega-3 and Omega-6 fatty acids are the two most important fatty acids in your dog’s diet. These fats help to reduce inflammation which can make allergies, bug bites, and other skin irritants less invasive. The Omega 3’s specifically work to lessen skin dryness which can eliminate dander, and itchiness. The fatty acids also help your dog grow healthy joints, and even keep their organs functioning properly. Omegas are also great for your dog’s heart health. 

Additionally, if you or any of your friends have a dog allergy, chances are the allergy is actually due to your dog’s dander, not their fur. If your dog has healthy skin and fur, it may actually calm some of the symptoms associated with dog allergies. Keep your pup and your guests comfortable by making sure your dog has an appropriate amount of Omega’s in their diet. 

signs of omega deficiency

Oftentimes it can be pretty clear when your dog isn’t getting the recommended amount of Omega’s. If your pup has an Omega deficiency the first thing you may notice is skin issues. Your dog may have greasy fur, dry fur, or in general, itchy skin. You may also notice dandruff forming due to their dry and itchy skin. You pup’s fur may eventually begin to thin out as well. Additionally, an Omega deficiency can lead to weight gain, ear infections, worsening allergies, and make it hard for your dog to heal in a timely manner. If you notice any of these symptoms it may be time to consult your doctor about trying out an Omega supplement.

You can purchase Omega 3, and 6 supplements such as fish oils to fight deficiencies from the inside. You can also purchase serums that you simply rub into your dog’s coat if you know you’ll have a hard time getting your pup to ingest a pill. 

Pure Salmon Oil

salmon oil

Salmon Oil is possibly the best fish oil you can purchase for your dog. It’s rich in Omega-3 fatty acids and also contains Omega-6. The Pure Salmon Oil is made from high-quality Alaskan Salmon that allows your dog to get the best, all-natural oils. In addition to these great all-natural oils, the salmon oil contains EPA (eicosapentaenoic) acid and DHA (docosahexaenoic acid). EPA can help reduce inflammation and reduce swelling. DHA is actually a component of the brain and adding natural DHA into their diets can improve brain function and your dog’s attention

We like the Zesty Paws Salmon Oil because it comes in an easy to use pump bottle. Simply pump the right amount into your dog’s food bowl, and they won’t even know it’s there. Your dog will get great nutrients from the inside out. The fatty acids found in this mixture will keep your dog’s coat looking great, help prevent dry itchy skin, and even improve joint and heart function. It’s an easy way to keep your dog nourished and healthy during the winter, or if they have chronically dry skin. You’ll be happy to hear that this product is made in an FDA registered facility in the USA, so you can be sure your dog is getting the best of the best.

We highly recommend Zesty Paws Salmon Oil to dogs of all sizes that need an additional supplement to get the fatty acids they need. This salmon oil will keep their coats silky smooth, give them joint support, cardiovascular help, boost their immune system, and give them the energy to stay active. 


Glucosamine is a critical natural substance specifically for senior dogs. It is a substance that naturally occurs in your dog’s body in healthy cartilage. The glucosamine works to repair body tissues and help your dog heal. Unfortunately, as your dog ages, they’ll start to slow down their production of glucosamine; eventually this will make it hard for your pup to repair their joints when they need it the most. If it gets bad enough, your dog may eventually develop arthritis. Fortunately, glucosamine supplements can help your dog rebuild healthy cartilage which can keep your dog’s joints feeling great and improve their activity levels.

Glucosamine is often paired with chondroitin; which is a great natural substance already found in your dog’s body. When taken with glucosamine, it can improve your dog’s joints even more and work to improve flexibility and mobility. 

signs of glucosamine deficiency

Glucosamine is not only used in dogs with diminishing amounts of it, but also to prevent diseases, such as arthritis. As your dog starts to get older, it may be a good idea to talk to your doctor about adding a glucosamine supplement into their diet. It can prevent arthritis and help your dog sustain healthy joints into their old age.

If your pup starts to show signs of achey, sore joints, you should talk to your doctor immediately about starting them on a supplement and working to curb the pain as much as possible.

The K9 Care Chews allow you to easily supplement your dog’s diet with glucosamine, vitamin C, and chondroitin.

Vitamin A

Vitamin A is a crucial vitamin for both dogs and humans. It can be found in a variety of healthy foods including carrots, pumpkins, fish oils, liver, and even spinach. It’s fairly easy to find dog treats that contain a healthy amount of Vitamin A if they use real vegetables. Of course, it’s always better to help your dog get their daily dose of vitamins through foods, rather than supplements. Supplements are typically synthetic, making it harder for your dog to absorb the nutrients. 

Vitamin A is great for your pup’s vision, skin, and even their coat. All dogs need Vitamin A to stay healthy; we recommend purchasing treats that your dog will enjoy that contain vitamin A. They’re much better for your dog than supplements, and often taste good. They contain yummy ingredients like sweet potato or pumpkin. 

signs of Vitamin A deficiency

Vitamin A deficiencies can be severe, but overloading your dog with vitamin A can lead to toxicity. It’s important that your dog has their recommended amount without it becoming excessive. If your pup has a vitamin A deficiency you may notice their vision worsening, their coat may become dull, and their skin may become itchy and irritated. Fortunately, it’s very easy to supplement your dog with extra Vitamin A through healthy treats and chews.

In addition to organic sweet potato, these treats contain Organic Oat Flour, Organic Rolled Oats, Organic Peanut Flour, Organic Canola Oil, Organic Cinnamon

vitamin b

Vitamin B is another great vitamin that all humans and animals need. Fortunately, vitamin B can be found in a variety of foods that you and your pup may already be eating. B1, B2, and B12 are the big three that you’ll often find in your dog’s treats or kibble. Vitamin B12 can be found in fish, poultry, and even dairy products. Vitamin B plays an important role in your dog’s health. It can make their blood less attractive to ticks and fleas, improve their skin health, and even improve their eyesight. 

Thiamine is an important B vitamin that is often hard to find in dog food’s. This is the important vitamin that makes your dog’s blood less attractive to harmful ticks. If your dog seems to get a lot of bug bites, it may be best to try a supplement to boost their thiamine levels. 

signs of a vitamin b deficiency

If your pup has a Vitamin B deficiency you may notice their skin symptoms first. Their skin may become dry and flakey, and they may begin to get more bug bites than usual. Fortunately, if your dog has fish or poultry anywhere in their diet, this can help boost their Vitamin B levels. 

vitamin d

Vitamin D works hard to help your dog balance the amount of calcium and phosphorous in their system. This helps your dog have healthy bones, nerve, and muscle control. Of course as many of you know, the best source of vitamin D is the sun! Unfortunately, as the days get shorter in the winter, and weather becomes more unpredictable, it can get pretty hard to get your dog outside often enough to get a healthy dose of vitamin D from the sun alone. Especially in the wintertime, you may need to help your dog keep their levels up through either supplements, or treats. 

signs of a vitamin d deficiency

If your dog starts getting a real vitamin D deficiency, you may notice weakness, insomnia, and nervousness. When this becomes severe enough they’ll eventually go into renal failure. If you think your pup may be experiencing a Vitamin D deficiency, check with their vet to find out if they need to supplement their diet with a multivitamin. Below you’ll find one of our favorite multivitamins for dogs.
