Dogs, unlike humans, can produce vitamin C in their bodies, and therefore do not need external sources of it. However, in certain circumstances, such as illness, stress, or cancer treatment, supplementing their diet with vitamin C can be beneficial. Before adding vitamin C supplements, it is crucial to consult a veterinarian to determine the appropriate dosage and potential adverse effects. Vitamin C-rich foods, such as citrus fruits, potatoes, and broccoli, can be fed fresh and uncooked to dogs as a natural way to boost their vitamin C intake.

| Why add vitamin C to a dog's diet? | Vitamin C can boost a dog's growth, immunity, and repair of body tissues. It can also help with the production of collagen, a protein that helps in the healing of wounds. |
| Do dogs need vitamin C? | Unlike humans, dogs can produce vitamin C in their bodies and do not require external sources of it to the same degree. However, dogs with cancer or other illnesses may benefit from additional vitamin C as they experience increased physiological stress that uses up vitamin C faster. |
| How to add vitamin C to a dog's diet? | Consult a veterinarian before adding vitamin C supplements to a dog's diet. Vitamin C can be added through fresh and uncooked fruits or vegetables, such as citrus, potatoes, broccoli, Brussels sprouts, cantaloupe, or strawberries. Human vitamin C products can also be given to dogs, but those intended for dogs may be absorbed better. |
| Dosage | The appropriate dosage depends on the dog's breed, size, age, health status, and overall health. Smaller dogs may require about 250 milligrams per day, while larger dogs may need up to 750 milligrams. It is important to start with a low dose and adjust based on the dog's specific needs under veterinary guidance. |
| Risks | Excessive vitamin C can lead to unnecessary side effects, such as calcium oxalate bladder stones, especially in male dogs due to the length of their urethra. |

What You'll Learn
Consult a vet first
Dogs can produce vitamin C in their bodies, so they do not need it in their diet. However, in some cases, adding vitamin C to their diet can be beneficial. For example, dogs with cancer experience increased physiological stress, which uses up vitamin C faster. Supplementing their diet with vitamin C can support their immune system and overall health.
If you are considering adding vitamin C supplements to your dog's diet, it is important to consult a veterinarian first. Human vitamins often have different concentrations from pet vitamins and may contain additives that are harmful to dogs. A vet can advise you on the appropriate dosage and potential adverse effects. Your vet may also recommend supplementing your dog's diet with specific fruits and vegetables, such as citrus, potatoes, broccoli, Brussels sprouts, cantaloupe, or strawberries, instead of vitamin supplements.
If your dog is sick or stressed, their vitamin C requirements may change, and their body may produce more vitamin C to cope. For example, a 1942 study found that dogs with skin diseases had very low amounts of vitamin C in their blood. In such cases, a vet may advise adding vitamin C to your dog's diet.
It is important to note that vitamin C supplementation is not needed for most dogs and can lead to unnecessary side effects. Giving your dog too much vitamin C can result in calcium oxalate bladder stones, especially in male dogs due to the length of their urethra. Therefore, it is always best to consult a veterinarian before adding any supplements to your dog's diet.

Natural synthesis
Unlike humans, dogs do not require external sources of vitamin C to the same degree. This is because dogs can produce vitamin C in their bodies, specifically in their liver, when given the raw ingredients in their food.
A well-balanced diet should provide dogs with the necessary ingredients to synthesize vitamin C. Dogs fed an appropriate commercial diet should not require vitamin supplements unless recommended otherwise by a veterinarian. Commercial dog food diets labelled “complete and balanced” are specially formulated to contain all of the vitamins, minerals, and nutrients your dog needs. Foods catered toward different life stages, like puppy food, adult dog dog, and senior dog food, contain different levels of certain vitamins, depending on the requirements of that life stage.
If you are feeding your dog a homemade diet, you may need to add supplements to ensure that they are getting enough vitamins with their meals. In this case, you should consult your veterinarian about the appropriate vitamin dosage for your dog. Human vitamins often have different concentrations of vitamins than vitamins specifically made for dogs, and may even contain additives that are harmful to dogs.
If you are supplementing your dog’s diet with naturally occurring vitamin C, you should give them fresh and uncooked fruits or vegetables. Just five servings of fruits and vegetables can pack more than 200 milligrams of vitamin C. Smaller dogs should get about 250 milligrams a day, medium dogs 500 milligrams, and large dogs 750 milligrams a day. Dogs with arthritis may benefit from Calcium Ascorbate, which is pH neutral and has the fewest side effects such as diarrhea or indigestion. Ascorbic Acid, a naturally occurring form of Vitamin C found in most human vitamin C pills, is not efficiently bioavailable to dogs and can cause intestinal distress. Sodium Ascorbate is another readily available and easily absorbed type of Vitamin C that stays in the system twice as long as Ascorbic Acid. It has been shown to benefit dogs with Addison's disease if given in low doses.
Some natural foods that contain vitamin C include:
- Blueberries
- Raspberries
- Strawberries
- Oranges
- Lemons
- Broccoli
- Kale
- Spinach
- Sweet potatoes
- Pumpkin
- Bell peppers
- Citrus
- Potatoes
- Brussels sprouts
- Cantaloupe
- Carrots
- Apples
- Melons
- Peaches

Dosage
Dogs can naturally produce vitamin C in their bodies, so they do not need it in their diet unless advised by a veterinarian. However, there are some circumstances in which vitamin C can be beneficial for dogs. For example, dogs with cancer experience increased physiological stress that uses up vitamin C faster, so supplementing their diet can support their immune system and overall health. Vitamin C can also be beneficial for dogs with Addison's disease, skin diseases, fevers, or those that have exercised to their limits.
If you are considering adding vitamin C supplements to your dog's diet, it is important to consult a veterinarian first. They will advise on the appropriate dosage depending on your dog's breed, size, age, health status, and specific needs. It is recommended to start with a low dose and adjust based on any changes or reactions. Smaller dogs should get about 250 milligrams a day, medium dogs 500 milligrams, and large dogs 750 milligrams a day. However, the dosage should be equal to the amount your dog normally creates, which is 18 mg of vitamin C per pound of body weight.
Vitamin C can also be added to a dog's diet through fresh and uncooked vitamin C-rich fruits and vegetables, such as citrus, potatoes, broccoli, Brussels sprouts, cantaloupe, and strawberries. Just five servings of fruits and vegetables can provide more than 200 milligrams of vitamin C. It is important to note that too much vitamin C can be harmful to dogs and can result in side effects such as diarrhoea or calcium oxalate bladder stones, especially in male dogs.

Potential side effects
While vitamin C can be beneficial for dogs in certain circumstances, it is not essential for their health. Dogs can produce vitamin C in their liver, and therefore, they do not need external sources of it unless they have a specific health condition.
However, there are some potential side effects of adding vitamin C to a dog's diet that you should be aware of. Firstly, it is important to consult with a trusted veterinarian before adding any supplements to your dog's diet, as too much vitamin C can be harmful to dogs. The appropriate dosage of vitamin C depends on factors such as the dog's breed, size, age, and overall health, and providing too much can result in an upset stomach or diarrhoea. Smaller dogs should receive about 250 milligrams of vitamin C per day, medium dogs 500 milligrams, and large dogs 750 milligrams. It is also important to note that vitamin C needs to be delivered fresh every day, as the body does not store this vitamin. Instead of giving a single daily dose, it is recommended to split the total amount into three or four smaller amounts throughout the day.
Additionally, when choosing a vitamin C supplement for your dog, it is worth considering that different forms of the vitamin have varying levels of bioavailability and effectiveness. The sodium ascorbate form of vitamin C is the most natural option and is well-absorbed by dogs, making it one of the best choices. In contrast, the ascorbic acid form of vitamin C, which is commonly found in vitamin pills for humans, can cause diarrhoea and heartburn when consumed in high concentrations or large doses. Using smaller doses of ascorbic acid several times a day can help alleviate these symptoms.
Overall, while vitamin C can be beneficial for dogs in certain cases, it is important to be aware of the potential side effects and always consult a veterinarian before adding any supplements to your dog's diet.
