Toxicity in animals
Main article: theobromine poisoning
In sufficient amounts, the theobromine found in chocolate is toxic to animals such as horses, dogs, parrots, small rodents, and cats (kittens especially) because they are unable to metabolise the chemical effectively. If they are fed chocolate, the theobromine will remain in their bloodstream for up to 20 hours, and these animals may experience epileptic seizures, heart attacks, internal bleeding, and eventually death. Medical treatment involves inducing vomiting within two hours of ingestion, or contacting a veterinarian.
(Anyone here ever see a horse vomit from anything other than choke?????)
I think the rule of thumb is " Don't feed your Dog Chocolate even know he likes it!, because bad things can happen to him! Same I find for horses, Were not talking about colic.....I have seen a quarter horse mare have a motor type seizure, and it's not pretty!
A typical 20-kilogram (40-lb) dog will normally experience great intestinal distress after eating less than 240 grams (8.5 oz) of dark chocolate, but will not necessarily experience bradycardia or tachycardia unless it eats at least a half a kilogram (1.1 lb) of milk chocolate. Dark chocolate has 2 to 5 times more theobromine, thus is more dangerous to dogs and other animals. According to the Merck Veterinary Manual, approximately 1.3 grams of baker's chocolate per kilogram of a dog's body weight (0.02 oz/lb) is sufficient to cause symptoms of toxicity. For example, a typical 25-gram (0.88 oz) baker's chocolate bar would be enough to bring about symptoms in a 20-kilogram (44 lb) dog. Of course, baking chocolate is rarely consumed directly due to its unpleasant taste, but other dark chocolates' canine toxicities may be extrapolated based on this figure. As dogs like the taste of chocolate products as much as humans do, and are capable of finding and eating quantities much larger than typical human servings, they should be kept out of their reach. Treats made from carob are a good substitute and pose no threat.
