Poisonous Foods for Your Dog
Furthermore, theobromine can cause cardiac irregularity, especially if the dog becomes excited. Cardiac arythmia can precipitate a myocardial infarct which can kill the dog.
Theobromine also irritates the GI tract and in some dogs can cause internal bleeding which in some cases kills them a day or so later.
Theobromine is also present in differing amounts in different kinds of chocolate. milk chocolate has 44-66 mg/oz, dark chocolate 450 mg/oz and baking/bitter chocolate or cocoa powder varies as much as 150-600 mg/oz. How much chocolate a dog can survive depends on its weight (and other unknown circumstances). Under 200 mg theobromine per kg body weight no deaths have been observed.
Theobromine will stay in the bloodstream between 14 and 20 hours. It goes back into the bloodstream through the stomach lining and takes a long time for the liver to filter out.
Within two hours of ingestion, try inducing vomiting unless your dog is markedly stimulated, comatose, or has lost the gag reflex. If your dog has eaten a considerable amount of chocolate, or displays any of the above symptoms, take it to the vet without delay.
In the absence of major symptoms, administer activated charcoal. The unabsorbed theobromine will chemically bond to this and be eliminated in the feces. In pinch, burnt (as in thoroughly burnt, crumbling in hand) toast will do.
