Can Dogs Eat orange peels?

The short answer is no, dogs should not eat orange peels. While the fruit of the orange is safe for dogs to eat in moderation, the peel is not. Orange peels contain a substance called psoralen, which can be toxic to dogs if ingested in large quantities.

Understanding the Composition of Orange Peels

Essential Oils in Orange Peels

Orange peels are rich in essential oils, which contain various compounds that contribute to the unique aroma and flavor of oranges.

The Role of Psoralen in Orange Peels

Psoralen is a compound found in the essential oils of many plants, including orange peels. It has been known to cause harmful health effects in dogs when ingested.

Other Compounds Present in Orange Peels

In addition to psoralen, orange peels also contain other compounds like d-limonene and linalool. These compounds can also be toxic to dogs, particularly in large amounts.

The Effects of Psoralen on Dogs

Gastrointestinal Distress

When dogs ingest psoralen, they may experience gastrointestinal distress. Symptoms include:


Vomiting is a common symptom of psoralen ingestion in dogs, as their body attempts to rid itself of the toxic compounds.


Diarrhea is another common symptom associated with psoralen ingestion in dogs.

Loss of Appetite

Dogs experiencing gastrointestinal distress due to psoralen toxicity may also lose their appetite.

Liver Damage

In severe cases, psoralen ingestion can lead to liver damage, which can be life-threatening if not treated promptly.


Psoralen can also cause photosensitization in dogs, making their skin more sensitive to sunlight and potentially leading to sunburn and other related skin issues.

Severe Poisoning and Death

In extreme cases, psoralen ingestion in dogs can result in severe poisoning and death. Therefore, it is crucial to keep orange peels away from your dog and seek immediate veterinary attention if ingestion occurs.

Factors Influencing the Toxicity of Orange Peels to Dogs

Size and Breed of the Dog

The size and breed of the dog can influence the severity of the toxic effects of orange peels. Smaller dogs and breeds with a genetic predisposition to liver issues may be more susceptible to the harmful effects of psoralen.

Amount of Essential Oils in the Peel

The amount of essential oils present in orange peels can also influence a dog's susceptibility to psoralen toxicity. Peels with higher concentrations of essential oils pose a greater risk to dogs.

Individual Sensitivity

Individual dogs may have varying sensitivity to psoralen and other compounds in orange peels, making some more susceptible to toxicity than others.

Preventing Orange Peel Ingestion

Proper Storage of Oranges and Orange Peels

To prevent your dog from ingesting orange peels, store oranges and orange peels in a secure location, away from your dog's reach.

Monitoring Your Dog's Diet and Environment

Regularly monitor your dog's surroundings to ensure they are not chewing on or ingesting potential hazards, such as orange peels.

Safe Alternatives to Orange Peels for Dogs

Orange Fruit

Dogs can safely eat the fleshy part of an orange in moderation. Oranges provide:

Nutritional Benefits

Oranges are a good source of vitamin C, potassium, and fiber, which can be beneficial to a dog's health if consumed in appropriate amounts.

Preparing Oranges for Dogs

When giving your dog oranges, be sure to remove the peel and any seeds, as these can be harmful to dogs.

Other Dog-Friendly Fruits

Some other dog-friendly fruits include apples, bananas, and blueberries. Always remove seeds and pits, and consult your veterinarian before introducing any new foods into your dog's diet.

Recognizing and Responding to Orange Peel Ingestion in Dogs

Signs and Symptoms of Psoralen Toxicity

If your dog ingests an orange peel, monitor them for signs of psoralen toxicity, including vomiting, diarrhea, loss of appetite, and abdominal pain.

When to Contact Your Veterinarian

If your dog shows any symptoms of psoralen toxicity, it is crucial to contact your veterinarian immediately.

Treatment Options and Recovery

Treatment for psoralen toxicity in dogs may include inducing vomiting, activated charcoal administration, IV fluids, and supportive care. With prompt treatment, most dogs can make a full recovery.
