Short answer

This is toxic and requires immediate action. Macadamia nuts can cause weakness, wobbliness, and tremors in dogs, typically within 12 hours of ingestion. While most dogs recover with supportive care, the symptoms are distressing and warrant a veterinary call. If your dog shows any of these signs or you know they've eaten macadamias, contact your vet or the ASPCA Animal Poison Control at 888-426-4435 right away for guidance.
