Can Dogs Eat Macadamia Nuts?
No — macadamia nuts are toxic to dogs. Even small amounts can cause weakness, vomiting, tremors, and hyperthermia.
Macadamia nuts are toxic to dogs
Macadamia nuts are one of the few nuts that are genuinely toxic to dogs. The exact toxin is unknown, but ingestion causes weakness (especially in hind legs), vomiting, tremors, hyperthermia, and lethargy. Symptoms usually appear within 12 hours. Chocolate-covered macadamias are doubly dangerous. Most dogs recover within 48 hours with supportive care.
