Every dog is different. Individual allergies and sensitivities are common — always introduce new foods in small amounts and watch for adverse reactions. This site is for informational purposes only and is not veterinary advice. Always consult your vet.
The Full Picture
Macadamia nuts are toxic to dogs. The exact toxin is unknown, but even small amounts can cause vomiting, weakness (especially in the hind legs), tremors, hyperthermia, and lethargy. Symptoms typically appear within 12 hours of ingestion. While macadamia nut toxicity is rarely fatal, it can be very uncomfortable and distressing for dogs. Chocolate-covered macadamia nuts are doubly dangerous. Contact your vet if your dog eats any amount.
What You Should Know
Macadamia Nuts should be kept well away from dogs. If your dog has eaten macadamia nuts, watch for symptoms such as vomiting, diarrhea, lethargy, or loss of appetite. In an emergency, contact your veterinarian or an animal poison helpline straight away.
