How much chocolate will kill a dog? The Merck Veterinary Manual puts a lethal dose (for 50% of the canine population) at 250 and 500 mg of theobromine per kg of body weight but warns that deaths have been reported at dosages as low as 115 mg/kg.
Will 1 chocolate chip hurt a dog? It’s the dose that makes the poison! Pets that ingest a few M&Ms or 1-2 bites of a chocolate chip cookie are unlikely to develop chocolate poisoning. For milk chocolate, any ingestion of more than 0.5 ounces per pound of body weight may put dogs at risk for chocolate poisoning.
What happens if my dog eats chocolate? Clinical signs depend on the amount and type of chocolate ingested. For many dogs, the most common clinical signs are vomiting, diarrhea, increased thirst, panting or restlessness, excessive urination, and racing heart rate. In severe cases, symptoms can include muscle tremors, seizures, and heart failure.
How long after eating chocolate will a dog get sick? Symptoms of chocolate poisoning will usually show within six to 12 hours, but could appear within one hour. If you know your dog has eaten chocolate, act immediately and don’t wait for the signs to appear. We always recommend seeking veterinary advice if you have any concerns about the health of your pets.
