The abovementioned symptoms are common in dogs that have eaten macadamia nuts and these symptoms usually appear within 8-12 hours of ingestion. There are also serious cases where your dog faces constant shaking, high fever, and an inability to walk. If you think your pooch has eaten even a small amount of macadamia nuts, contact the vet at once. Experts at the ASPCA Animal Poison Control Center state that in most cases, the negative effects are mild and can be managed at home.

The treatment for macadamia nut poisoning usually depends on how severe the symptoms are. In most cases, the toxicity can be removed by vomiting.

Fortunately, most dogs recover without any specific treatment. Severely affected dogs might also be given supportive treatment including fluids, antipyretics, or analgesics.
