Can Dogs Drink Orange Juice?

Did you know that 95 to 98% of all reported animal cases account for dog owners seeking assistance for potential poisoning?

This mostly happens in the summer and in December, associated with the holiday season.

Summer is a time when many pet owners like to give their dogs orange juice. But, is it a safe choice?

In this article you will learn about the safety of orange juice for dogs, how many oranges it can eat per day, what situations your dog may benefit from drinking orange juice and a lot more.

Can Dogs Drink Orange Juice?

To quickly answer your question… Yes, they can. But only in limited amounts and there are a few things you should know.

Is Orange Juice Safe For My Dog?

Dog’s nutritional needs are different than ours. They only need their canine food and fresh water to have a healthy life.

Oranges are rich in vitamin C, but dogs produce their own vitamin C naturally and automatically. (source: Page 10)They produce it through their glandular systems; and in healthy conditions, they produce about 18mg of vitamin C for every pound they have. (source)

Therefore, giving your dog orange juice is practically useless since it does not boost their immune system.

Negative Effects of Orange/ Orange Juice On Dogs

Oranges are naturally rich in sugar, and dogs should avoid sugar in general. The acid content of the orange can also destroy its teeth enamel if it drinks too much orange juice over time.

Enamel: The hard glossy substance that covers the crown of a tooth.

Vitamin C (ascorbic acid) overdose is also a concern.

When it is supplied in smaller quantity, it has the pre-oxidant property that helps with cell oxidation and damage.

According to Dr. Deborah Linder, the head of the Tufts Obesity Clinic for Animals – the misconception of giving our pets vitamin C in the hope of preventing bladder stones or diseases can make things worse; this is because there has not been any scientific studies that proves so. (source)

Based on an animal study, animals that have a high dose of vitamin C led to severe joint damage compared to those on a low dose. (source)“There is not really a limit to how much vitamin C a pet can have because it is water soluble and excess levels are urinated out and don’t accumulate in the body,” says Liffs.

And don’t think that your dog will get bored of only drinking water from a bowl.

Water is the only thing dogs need to stay hydrated.

What About Oranges?

According to vets, oranges are not toxic for dogs, but too much orange can make its stomach upset.

Smaller dogs  should eat between 1/4 to 1/3 of a whole orange; while medium-sized and larger dogs can have an entire orange.

“There is not really a limit to how much vitamin C a pet can have because it is water soluble and excess levels are urinated out and don’t accumulate in the body,” says Stephanie Liff, DVM and partner at Brooklyn Cares Veterinary Hospital in New York.

The peel has lots of of concentrated vitamin C and additional vitamins and minerals. However, giving dogs rinds is not advisable because they are hard for dog to digest, leading to gastrointestinal upset.


Not all dogs like the taste of oranges. But some dogs will eat anything in front of them, including the peel.

Now you already know that dogs produce Vitamin C naturally, so there’s no need for them to get it from additional supplements.

But there are a few situations in which your dog might highly benefit from oranges.

Situations Your Dog Benefits From Oranges/ Orange Juice:

Your Dog Is Old

As dogs get older, their system becomes less proficient at producing vitamin C and need more antioxidant. In this case, offering additional vitamin C supplements to an older dog’s diet may help to reinvigorate them.

Your Dog Ate Something Toxic

If your dog ingested something toxic like onion powder, propylene glycol or any other oxidative toxins, a dose of vitamin C might be helpful due to all of its nutrients.

Your Dog Is Over-Exercised or Stressed

According to Christine Keyserling, DVM at The Animal Medical Center in NYC, extreme exercise or stress can overwhelm the liver’s capacity to produce vitamin C in some dogs. (source)

In this case, it is advisable that you give additional vitamin C supplementation.

But for most dogs, this is not necessary.
