Can Dogs Eat Macadamia Nuts?

Have you heard of the Queensland nuts? They are simply Macadamia nuts or Australian nuts in some parts of the world since the trees are native to Australia, specifically New South Wales and Queensland.

Macadamia nuts are toxic to dogs even though your canine will gladly wolf them whether plain, salted, baked, or coated with chocolate. Even a tiny amount of these nuts can cause poisoning to your furry friend.

Sensitivity to macadamia nuts varies from dog to dog, and while some have a rapid, severe reaction for others, the symptoms build up more slowly and painfully. Puppies are more likely to choke or have digestive blockage when eating macadamia nuts.

Symptoms of macadamia toxicosis are evident when your dog ingests as little as 0.7g per kg. So, macadamia nuts are entirely off-limits for your dog. The high-fat content can also irritate the stomach and cause canine pancreatitis, although this is rare.

My Dog Ate Macadamia Nuts. What Next?

Most symptoms are mild, with vomiting for 24 hours that resolves on its own without treatment. But if your dog has a fever, is vomiting non-stop, has severe weakness in the rear limbs, and tremors, you should rush to the animal clinic.

Your vet will conduct a tailored assessment of your pup and the macadamia nuts. Are the nuts salted or covered in chocolate?

Your vet will consider all the macadamia nut’s ingredients and underlying health conditions that may lead to severe poisonings like diabetes, kidney disease, osteoarthritis, and heart disease.

Your vet may induce vomiting to expel the nuts and offer activated charcoal to prevent further absorption of toxins into your pup’s system. The vet may also administer gastric decontamination or a cathartic medication such as sorbitol to induce bowel movements and quickly expel the nuts from the digestive system.

Pain and anti-nausea medication, fluid therapy, and muscle relaxants will be administered. If there are signs of respiratory distress, oxygen might be helpful.

Pups that chow down macadamia nuts with other toxins like raisins and chocolate are at higher risk of developing complications and need more aggressive treatment. If many nuts were consumed, the vet is likely to keep your dog in for 48 hours to monitor his symptoms.

Will My Dog be Okay?

All known cases of macadamia poisoning in dogs have resulted in full recovery. But consumption of other toxic substances like chocolate or raisins can result in a different yet fatal prognosis. However, if your pup consumed macadamia nuts only, don’t panic. They tend to get better within a day or two after the symptoms start to show.
