Most of us have heard that chocolate can make dogs sick. But how serious is the risk?
Your Dog Ate Chocolate: Now What? ..After eating a potentially toxic dose of chocolate, dogs typically develop diarrhea and start vomiting.
If the dog isn't vomiting on its own, the vet may advise inducing vomiting immediately to keep as much theobromine as possible from entering the system.
One method is giving the dog a one-to-one solution of hydrogen peroxide and water. But DeHaven says that treatment is now discouraged because it can cause esophageal ulcers.
She recommends syrup of ipecac, which induces vomiting.
When a dog shows signs of hyperactivity and agitation or is having seizures, the faster you get it to the vet the better. But there is no specific antidote for chocolate poisoning.
Usually, after vomiting is induced, activated charcoal is given to help prevent the absorption of the remaining toxins. Fluids are typically given along with intravenous drugs to limit seizures and protect the heart.
Symptoms of theobromine poisoning generally occur within four to 24 hours after chocolate is consumed.
