Dog Facts

Do dogs eat macadamia nuts?


No, dogs should not eat macadamia nuts at all!    

Macadamia nuts and any foods that contain macadamias are some of the most poisonous foods for dogs, and they can be fatal.

These nuts are cultivated from Macadamia integrifolia in the USA and Macadamia tetraphylla in Hawaii and Australia. The mechanism of toxicity is not known, meaning we are not sure why dogs are affected. Just a few raw or roasted macadamia nuts can make your dog sick.

Symptoms of poisoning include weakness, vomiting, ataxia, muscle tremors, depression and a change in body temperature.

Dogs are the only species in which these signs have been reported.

Diagnosis is usually based on the history of exposure (symptoms typically appear within 12 hours of ingestion), along with the clinical signs; symptoms usually last between 12 and 48 hours.

There is no specific antidote for this toxin but fortunately most dogs will recover with supportive treatment and nursing care (intravenous fluids, pain relief and anti-fever medications).
