Can Dogs Eat Macadamia Nuts?
Short answer: No. Macadamia nuts are toxic to dogs, and even a small amount can cause severe symptoms. Call your vet even if your dog ate only one.
Why it’s a problem
The AKC says macadamia nuts are toxic to dogs, although the exact toxin hasn’t been identified. Symptoms can occur from about 1/10 ounce per roughly 2 pounds of body weight. Weakness, especially in the hind legs, is the most common sign. Treatment is more aggressive if a large amount was eaten or chocolate was involved.
How much and how to serve it
None. Keep macadamia nuts, mixed nuts and cookies containing them out of reach.
Risks to watch for
- Weakness, especially in the hind legs.
- Lethargy, vomiting, diarrhea, tremors and fever.
- Lack of coordination and overheating.
- Serious cases: constant shaking, high fever and inability to walk.
What to do if your dog ate macadamia nuts
Call your vet as soon as possible, even if your dog ate only one nut. You can also call the Pet Poison Helpline at (855) 764-7661 (a fee applies) or the ASPCA Animal Poison Control Center at (888) 426-4435. Don’t induce vomiting unless a vet tells you to.
