when do symptoms of chocolate toxicity start
Symptoms of chocolate poisoning typically begin within two to four hours after ingestion. They include vomiting and diarrhea. These symptoms are followed by hyperactivity, muscle tremors, rapid pulse, increased urination and fever. In severe cases, symptoms such as seizures, coma, heart failure and death can occur within 12 to 36 hours of ingestion. If you suspect your dog ate chocolate, contact your veterinarian immediately.
