A dog suffering from metaldehyde poisoning is the type of emergency which will need immediate hospitalization and treatment. Unfortunately, there is no antidote available. The only course of treatment is to eliminate the metaldehyde from the dog's body. Your veterinarian will pump the dog's stomach and, if it is not convulsing, give activated charcoal to absorb the poison in the stomach and intestines. The dog will be restrained to prevent injury. Fluids are also often necessary to rehydrate the dog.
It is important to not feed a dog that is convulsing or vomiting. Overall prognosis ultimately depends on the amount of metaldehyde ingested, time to treatment, and quality of care provided. If left untreated, however, a dog may die within few hours of ingestion. Watch your dog for vomiting and other symptoms, and call your veterinarian immediately.
