Can Dogs Eat Grapefruit?

Grapefruits aren’t the best choice you can make when choosing which fruit is good for dogs. Although they contain lots of vitamins and minerals that are good and beneficial for dogs, it will be better if dogs avoid eating them.

Oranges, grapefruits, lemons, and limes are citrus fruits. They contain different amounts of citric acid. But lemons and grapefruits are higher in citric acid than oranges, and because of that, oranges are safe for dogs if given in moderation.

But that doesn’t go with grapefruits and lemons. They should be avoided as their consumption can lead to serious digestive problems.

Why Dogs Shouldn’t Eat Grapefruits?

Dogs shouldn’t eat grapefruits as they are high in citric acid. This high concentration of citric acid can irritate the stomach of the dog. It can cause loose stool, vomiting, bloating, etc.

But it’s very likely your dog to not even try to eat this fruit as dogs don’t like the bitter taste in food – for them, it means something negative – mostly even poisonous and this comes from their animal instinct.

You should expect such a reaction from dogs when they are offered to eat fruits that high in citric acid.

The flesh of the grapefruit is very acidic but not toxic while the rind contains natural essential oils that can be toxic to dogs. That’s why it’s better if this fruit isn’t given to dogs and if you have some doubt that your dog consumed any part of the fruit, contact your vet immediately.

Can Dogs Eat Grapefruit: Vitamin C

There is an interesting fact that dogs can produce their own vitamin C. That’s why it’s good if we don’t give them foods that are high in vitamin C often as they can overdose with it.

Most mammals, including dogs, can synthesize enough ascorbic acid for their requirements, and ascorbic acid may be reversibly oxidized to dehydroascorbic acid in the body, indicating that it is a dispensable nutrient for these species.

This quote is from the research of the National Library of Medicine of the United States done in 2006. The research is actually done for dogs with a portosystemic shunt but they compare the synthesis of vitamin C in healthy dogs and dogs with the portosystemic shunt (PSS).

Vitamin C is synthesized in the liver of dogs and is very important for dogs as it keeps the immune system strong and prevents diseases.

Can Dogs Eat Grapefruit: Nutritional Benefits

Although grapefruits are very rich in vitamin C and antioxidants they aren’t needed for dogs if they have a balanced and nutritional diet. As you already got know dogs don’t need extra vitamin C if they are healthy and can synthesize it. They need it only if they can’t synthesize it.

And dogs should be getting enough antioxidants from their food or if you want to give them a bit more then you can choose a better fruit like pineapple, kiwi, nectarines, and many more.

What Can Happen If My Dog Ate Too Much Grapefruit?

If your dog ate too much grapefruit it may experience vomiting, diarrhea, and gastrointestinal upset. It’s very possible for your dog to develop toxicity. That’s why it’s best to contact your vet when you notice what amounts were eaten or if your dog had the rind of a grapefruit.
