Clinical signs usually occur within 6 to 12 hours of ingestion. Initial signs include polydypsia, vomiting, diarrhea, bloating, and restlessness. Signs progress to hyperactivity, polyuria, ataxia, tremors, and seizures. Other effects include tachycardia, premature ventricular contractions, tachypnea, cyanosis, hypertension, hyperthermia, and coma. Less commonly, bradycardia and hypotension may occur. Hypokalemia is possible late in the course of the toxicosis. Because of the high fat content of many chocolate products, pancreatitis is a potential sequela 24 to 72 hours after ingestion. Death is generally due to cardiac arrhythmias or respiratory failure.
Based on ASPCA Animal Poison Control Center (APCC) experience, mild signs occur in animals ingesting 20 mg/kg of theobromine and caffeine, severe signs are seen at 40-50 mg/kg, and seizures occur at 60 mg/kg (ASPCA/APCC Database: Unpublished data). Accordingly, less than 1 oz of milk chocolate/lb (2 oz/kg) is potentially lethal to dogs; for baking (unsweetened) chocolate, less than 0.1 oz/lb (0.2 ounces/kg) is potentially lethal. Methylxanthines can cross the placenta and pass into the milk, so unborn or nursing offspring can be affected by chocolate toxicosis in the dam.
