Macadamia Nuts — toxicity in dogs

Call your vetApplies to: dogs.

Overview

Macadamia nuts are toxic to dogs, though the exact mechanism of toxicity is not fully understood. Dogs typically develop symptoms after eating 2-6 grams of macadamia nuts per kilogram of body weight. While macadamia nut poisoning is rarely fatal on its own, it becomes significantly more dangerous when combined with chocolate - a common pairing in cookies, candy, and baked goods. If your dog ate chocolate-covered macadamia nuts, treat it as a high-severity emergency. Cats do not appear to be affected, but limited data exists.

Symptoms

Weakness, vomiting, tremors, hyperthermia, inability to walk

Typical onset

12 hours

What to do

Contact your vet. Most dogs recover within 48 hours, but monitoring is important.
