Unsafe for Dogs

Safety Information

Highly toxic to dogs.

Important Notes

The Dangers of Macadamia Nuts

  • Ingestion of macadamia nuts leads to a condition known as macadamia nut toxicosis. The high fat content can also trigger pancreatitis, a painful and serious inflammation of the pancreas.
  • Symptoms of macadamia nut poisoning typically appear within 12 hours and can include:
  • Severe weakness, especially in the hind legs (this is a hallmark sign)
  • Lethargy and depression
  • Vomiting
  • Tremors
  • Lack of coordination (ataxia)
  • Elevated body temperature (hyperthermia)
  • While the toxicosis is usually not fatal and tends to resolve within 48 hours with veterinary care, it is a serious and distressing condition for your dog.

What to Do If Your Dog Eats Macadamia Nuts

If you suspect your dog has eaten macadamia nuts, contact your veterinarian or an animal poison control center immediately. They can provide guidance on the next steps, which may include inducing vomiting or providing supportive care to manage the symptoms. Be especially careful with baked goods like cookies or brownies, as these often contain hidden macadamia nuts mixed with other toxic ingredients like chocolate.

The Bottom Line

Macadamia nuts are poisonous to dogs. There is no safe amount. Keep all products containing macadamia nuts securely out of your dog's reach.

Emergency Notice

If your dog has consumed macadamia nuts, contact your veterinarian or the ASPCA Animal Poison Control Center (888) 426-4435 immediately.

General Feeding Guidelines

Introduce new foods gradually to monitor for allergic reactions or digestive issues.

Treats and human food should make up less than 10% of your dog's daily caloric intake.

Always consult with your veterinarian before making significant changes to your dog's diet, especially if your dog has pre-existing health conditions.
