What is Macadamia Nuts Poisoning?

Macadamia nut trees belong to the Proteaceae family, a group of flowering trees found mainly in the southern hemisphere. Several species, Macadamia integrifolia and treaphylla, are cultivated for their nuts which are frequently used in cookies and candy, or eaten by themselves. Macadamia nuts have been found to be poisonous to dogs. It’s not known what causes this toxicity, which does not seem to affect cats or humans. The Animal Poison Control received 48 calls from 1987-2001 with dogs presenting similar symptoms after macadamia nut ingestion and the results were replicated in a study. The symptoms of macadamia nut poisoning are typically non-fatal and resolve within 48 hours. Weakness is the most common sign, followed by lethargy, lack of muscle control, tremors, and fever.

Doses as low as 2.4 grams per kilograms of the dog’s weight have been found to affect muscle strength, with other symptoms such as vomiting and fever being more apparent with larger amounts. Doses as high as 62.4 grams per kilogram have been recorded. Immediate treatment can reduce absorption and hasten the passage of the nuts through the dog’s system. If a large amount was ingested, supportive treatment may also be needed to limit the severity of the symptoms and make the dog more comfortable. In most instances the condition will pass by itself, however if other toxic foods have been ingested at the same time (such as raisins or chocolate), there can be further complications.

Macadamia nuts cause symptoms of weakness and lethargy when they are ingested by dogs. This is called macadamia nut toxicity or toxicosis. Most symptoms will resolve in about 48 hours.

Causes of Macadamia Nuts Poisoning in Dogs

These are some of the risk factors associated with macadamia nut toxicity.

  • Cookies left out to cool
  • Open containers of trail mix at a party
  • Dogs chewing through a bag
  • Owner feeding nuts to their dog
  • Dogs that like to eat sweet or salty foods

Diagnosis of Macadamia Nuts Poisoning in Dogs

Diagnosis of macadamia nut poisoning is based on the symptoms and a history of macadamia nut ingestion. If you didn’t see the incident, missing food, chewed containers, or pieces of undigested nuts in the stool can be a good indication. With macadamia nut poisoning, dogs will often have an elevated serum lipase activity on a blood test, as well as hyperthermia (higher than normal body temperature) and signs of muscle weakness are obvious on a physical examination. Further testing may be needed to check for infection or more serious poisoning like ethylene glycol toxicity, especially if there is no known history of macadamia nut ingestion. Chocolate and raisins are also toxic to dogs and more likely to be fatal than macadamia nuts, so ingestion of products like trail-mix with raisins, chocolate covered macadamia nuts, or cookies with raisins and/or chocolate could result in several concurrent toxicities.

Treatment of Macadamia Nuts Poisoning in Dogs

Vomiting may be induced with cases of recent poisoning and activated charcoal may be given to reduce further absorption in the stomach. A cathartic medication like sorbitol will help to induce bowel movements and eliminate the nuts faster. Other treatments will be based on the symptoms. Medication may be given to reduce fever and make your dog more comfortable. In rare cases intravenous fluids may be necessary. If a large amount was ingested, the veterinarian may want to keep your dog for 48 hours to monitor the symptoms. Other concurrent poisoning like chocolate or raisin toxicity might need more aggressive treatment.

Recovery of Macadamia Nuts Poisoning in Dogs

Almost all known cases where macadamia nut was the only toxin ingested have resulted in a full recovery. It’s still a good idea to seek treatment however, especially with large doses. Combination with another substance that is more toxic could result in a different prognosis. Chocolate or grape poisoning can both be fatal without treatment. Prevention is the best way to manage macadamia nut poisoning. Don’t leave cookies out to cool in a place your dog can reach. Keep bags on a high shelf or in a dog-proof plastic container. Dispose of old or spoiled nuts in a sealed garbage can and, if possible, train your dog to avoid unknown foods.

back leg weakness

My dog managed to get into a small can of mixed nuts which contained macadamias, by the time we found her she had eaten practically the whole can. Next day she has been asleep all day and not acting like herself, when I went to pick her up to move her she started growling when I put my hand near her back legs. Also when she tried to jump on the couch her hind legs gave out and i had to help her up. She weighs about 12-15lbs.

Thankfully macadamia nut poisoning isn’t fatal in dogs but may cause gastrointestinal symptoms, ataxia, weakness among other symptoms; there is no specific treatment for macadamia nut poisoning apart from ensuring that a dog remains hydrated. Other types of nuts may cause pancreatitis due to the oily fat content, you should monitor Lulu for the time being but if there is no improvement by Monday morning you should visit your Veterinarian.

Hi there! I have a 45lb female red husky and she at about 4 macadamia nuts. She's fine at the moment since we just caught it but looking up on the Internet just tells me how toxic it is im afraid and just want to know if the amount she ate is worrisome and if we should induce vomiting.

Most cases of macadamia nut poisoning results in gastrointestinal symptoms like vomiting; typically symptoms appear after dogs eat around 1g/lb body weight, but this can vary dog to dog. One macadamia nut weighs around 2.6g, so four nuts would be 10.4g which is well below toxic levels. Keep an eye on her for the time being and visit your Veterinarian if you have any concerns.

Whilst macadamia nuts may cause some gastrointestinal symptoms, they are not considered toxic; however, I am more concerned with the consumption of raisins and chocolate which are both toxic to dogs - raisins can cause kidney failure and chocolate may cause a variety of symptoms including cardiovascular and neurological symptoms, both may lead to death in severe cases. If you have an emergency clinic near by, I would recommend that you visit; otherwise keep an eye on Oakley and administer activated charcoal every eight to twelve hours until you visit your Veterinarian in the morning.

My dog’s hind legs has been weak for a month now and i suspect someone from the household fed her macadamia. Though no one would admit to it, macadamia nuts is a staple so there is a possibility. What can i do to improve her condition since it’s already been awhile since the symptoms started.

My dog ate two white chocolate chip macadamia nut cookies. She isn't showing any signs of weakness or vomiting but I am not sure if I should still take her to the vet. She played catch for about an hour after consuming and she's been fine. She also ate a doggy treat before I realized she ate the cookies but she is acting normal. Should I just keep a close eye on her or should I take her to the vet?

Ingestion of 2.4mg/kg (or 1.2mg/lb) of macadamia nuts have been linked to clinical signs of vomiting, ataxia, weakness, hyperthermia, and depression; for small ingestion of macadamia nuts dogs usually recover well within 24-48 hours. If you have 3% hydrogen peroxide you should induce vomiting to be safe and administer activated charcoal to reduce the severity of any symptoms that Cercey may have. Also, whilst not as toxic as regular chocolate, white chocolate still contains some theobromine so care should be taken there too. Regards Dr Callum Turner DVM

I'm reading through the comments on here and I just want to make sure I'm understanding. My dog weighs just under 13 lbs and she ate half a white chip macadamia nut cookie. I can't imagine that there were any more than 3 each of white chocolate chips and macadamia nut pieces (not even whole nuts probably.) Should I induce vomiting or leave her alone as it is really stressful on her stomach whenever I have to make her throw something up?
