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:

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

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

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