Vitamin C, also known as ascorbic acid, is incredibly important for normal immune function in mammals, including dogs. It promotes the activation of white blood cells, which is the body’s principal means of fighting off infection.

It also has some other functions we’ll discuss later. However, dogs are able to produce vitamin C within their bodies, unlike humans, and so don’t need a dietary source. But first, are there safe foods you can offer your dog to get more Vitamin C into their system? Let’s take a look.

The 10 Foods with Vitamin C for Dogs

1. Commercial Dog Food

Most dog food manufacturers use vitamin C to fortify their blends because it’s good for your dog and acts as a preservative. Feeding a high-quality dog food is the easiest option because there’s no preparation involved, and chances are your dog won’t turn its nose up at it.

2. Bell Peppers/Capsicum

These non-spicy members of the chili family can be a tasty and refreshing snack for your dog that is packed with vitamin C and lots of other great nutrients. Best served raw, bell peppers can be sliced into strips or bite-sized pieces and served cold on a summer’s day. The seeds are safe to eat; they’ll just make a mess!

Having one of the highest levels of vitamin C of all fruits and vegetables, bell peppers are an ideal ingredient for humans and guinea pigs, too, another species that can’t make their own.

3. Broccoli

Broccoli can be fed to your dog raw or cooked, as long as you don’t add any oils or seasoning. You should always serve it in small quantities because the florets contain isothiocyanates which cause gastric irritation in dogs.

4. Brussels Sprouts

The best way to serve Brussels sprouts is to boil, steam, or microwave them for your dog and keep them plain. Steaming will preserve most of the nutrients. Choose firm and green sprouts, wash them, and cut off the stem, so the leaves are left intact.

Steam them for around 5 minutes or microwave them in water for 8 minutes. Boiling will take longer (around 10 minutes) and preserve fewer nutrients. Never serve them raw, as they’ll be too hard to digest.

5. Oranges

Oranges are safe for your dog in small quantities, although not all dogs will enjoy the tart taste. Oranges have a moderate sugar content, and if your dog eats too much, it can suffer from gastrointestinal upset. Make sure you peel the orange and remove all the seeds before offering them to your dog.

6. Cauliflower

Cauliflower is considered to be a yummy meat substitute and a nutrient-rich superfood. Dogs can eat it raw or cooked, but, as always, keep it plain. You can sprinkle it over their regular dog food for a crunchy topping or give your dog a small piece as a treat.

7. Carrots

Cooked and raw carrots are good options for dogs, but you should wash and peel them to remove all dirt and pesticides. You must also cut them into bite-sized chunks to prevent choking, especially in smaller dogs.

8. Apples

Peeling an apple will make it easier to digest, and cutting it into bite-sized pieces is essential to prevent choking. You will also need to remove all the seeds, as they contain a small amount of cyanide which is toxic and can harm your dog in large doses.

The apple core and stem could also choke your dog, so removing them is best.

9. Melons

You will first have to remove the seeds and rind from your melon to prevent choking. The rind is also difficult to digest, so it’s best to keep this away from your dog entirely. You will need to cut the fleshy part of the melon into bite-sized chunks before serving it to your dog.

10. Peaches

Peaches cut into safe pieces are a perfect snack for your dog. Avoid canned peaches as they contain high amounts of sugar and might also be treated with artificial sweeteners or preservatives that can upset your dog’s digestive system.

The peach pit is particularly hazardous as it’s a choking hazard and contains amygdalin, a sugar-cyanide compound. A dog would have to consume several peach pits for them to be affected, but it’s still worth remembering, as there is no point in taking the risk. Lastly, if you have a peach tree in your garden, be aware that the leaves and stems contain cyanide.
