There are few fruits as fragrant as the sweet-smelling orange but while humans consume them by the bucket loads can dogs eat oranges? 

If you’ve been wondering whether oranges are among the human foods dogs can eat then you’ll be pleased to know that the answer is a big fat juicy yes! While not all fruits and vegetables are suitable for dogs, small amounts of orange flesh can be a lovely snack for your pup and a healthy addition to their diet.

Packed full of vitamin C, potassium, and fiber, oranges can give your furkid’s immune system a boost and help the digestive system to function smoothly. Let’s dip into the fruit bowl and peel back the layers of the humble orange to get the lowdown on whether this sweet treat is good for your furkid and how much of the orange stuff is too much. 

How much of an orange can dogs eat?

Oranges aren’t toxic for dogs so you don’t have to worry about letting them have a taste of this juicy fruit. But as with everything, moderation is key. 

Fruit is classed as a treat food and shouldn’t make up more than 10% of your dog’s daily diet - one segment of orange flesh for a small dog and up to three for a large dog is ample, provided they have no underlying health conditions. 

Some dogs aren’t keen on the tart taste and strong smell of oranges, so pop a segment down in front of them and let them have a sniff before you incorporate orange into any doggy recipes. Have some of the best dog treats in reserve should they not be keen.

Is the vitamin C in oranges good for dogs?

While some pet parents like to add oranges to their dog’s diet due to their high vitamin C content, healthy dogs are able to produce their own amounts of this vitamin so it’s not a must for them from a nutritional point of view - unless they’re highly active.

Although most vets and nutritionists have long considered added vitamin C to be unnecessary for dogs, there is a growing consensus that it may be beneficial for exceptionally active dogs.

“In some dogs, extreme exercise or stress can overwhelm the liver’s capacity to make vitamin C,” explains Dr. Christine Keyserling, a New York-based vet. “In these cases, it may be beneficial to provide additional vitamin C supplementation. However, for most pets, it’s not required.”

Can eating oranges be dangerous for my dog?

For most dogs, a daily dose of orange is fine if they enjoy it but it’s a no-no for dogs with certain health conditions.

At around 9% sugar, oranges aren’t suitable for overweight dogs or those that suffer from diabetes. While the sugar in oranges is natural, it can still cause fluctuations in the blood sugar levels of diabetic dogs and the excess calories can cause already portly pups to pile on more pounds.

Oranges are also high in acid and while the fiber content can help with the formation of healthy stools in many dogs, for those with sensitive digestive systems the extra acid can lead to gastrointestinal upsets and have the reverse effect, causing diarrhea

It’s important if you’re feeding your dog oranges that you only give them the flesh and never the peel or white pith. Both of these parts can contain toxic compounds and the peel can cause blockages in the bowel or cause your canine companion to choke. The oils in the peel also upset the digestive system, resulting in vomiting, diarrhea, and dehydration.
