Dog Ate Macadamia Nuts: What to Do, Symptoms, and When to Seek Care

If your dog ate macadamia nuts, it’s important to take it seriously. Macadamia nuts are toxic to dogs and can cause a range of symptoms, even in small amounts.

While most cases are not life-threatening, symptoms can be uncomfortable and sometimes severe, so prompt care is recommended.

What to Do If Your Dog Ate Macadamia Nuts

If your dog has eaten macadamia nuts, take these steps right away:

• Remove any remaining nuts so your dog cannot eat more
• Estimate how many nuts were consumed
• Check if the nuts were plain or flavored (seasonings can add risk)
• Note your dog’s weight and the time of ingestion
• Call a veterinarian for guidance

Are Macadamia Nuts Toxic to Dogs?

Yes, macadamia nuts are toxic to dogs, though the exact mechanism is not fully understood. Even small amounts can cause symptoms, especially in smaller dogs.

The risk may increase if the nuts are coated with chocolate, salt, or other flavorings.

Symptoms of Macadamia Nut Toxicity in Dogs

Symptoms typically appear within 6–12 hours after ingestion and may include:

• Weakness (especially in the hind legs)
• Difficulty walking or standing
• Lethargy
• Vomiting
• Tremors
• Fever
• Joint stiffness or pain

Most dogs recover within 24–48 hours with supportive care, but symptoms can be distressing.

When Should You Call a Veterinarian?

You should contact a veterinarian if:

• Your dog ate any amount of macadamia nuts
• You are unsure how many were consumed
• Your dog is showing symptoms
• The nuts were coated with chocolate or other toxic ingredients
• Your dog is small, a puppy, senior, or has underlying conditions

Even if symptoms seem mild, monitoring and care are important.

How Vets Treat Macadamia Nut Toxicity

Treatment focuses on supportive care and symptom management.

Treatment may include:

• Inducing vomiting if ingestion was recent
• IV fluids to support hydration
• Medications to control vomiting or pain
• Monitoring for neurologic symptoms
• Supportive care until symptoms resolve

Most dogs improve with timely treatment and monitoring.

This level of care must be provided by an emergency or urgent care veterinary hospital, as AnimALL Mobile Veterinary Service is not able to provide emergency treatment.

What to Do Next

Macadamia nut toxicity is usually temporary but can still cause significant discomfort. If your dog has eaten macadamia nuts, it’s best to have them evaluated.

Contact ASPCA Animal Poison Control at (888) 426-4435 or the Pet Poison Helpline at (855) 764-7661 for guidance, then take your dog to your nearest emergency or urgent care veterinarian for treatment.

If your pet is showing signs of a life-threatening emergency, please go directly to the nearest emergency veterinary hospital rather than waiting for a mobile appointment.
