Dogs Poisoned by Chocolate

Why chocolate poisons dogs and how to treat chocolate dog poisoning.
The problem, according to veterinary experts, is that eating a speck of chocolate leads a dog to crave more. It can mean that your dog will jump at a opportunity to get any type of chocolate, not knowing that certain chocolates are more lethal than other types. Larger amounts of chocolate, particularly of the most toxic type, can bring about epileptic seizures in some dogs, and in all dogs, can kill.
Poisoning of dogs by chocolate is not as uncommon as you might think.
Why is Chocolate Lethal?
Chocolate contains theobromine. A naturally occurring stimulant found in the cocoa bean, theobromine increases urination and affects the central nervous system as well as heart muscle. While amounts vary by type of chocolate, it's the theobromine that is poisonous to dogs.
Symptoms of Chocolate Dog Ingestion and Poisoning
You can recognize that your dog has eaten a toxic dose of chocolate from the symptoms. Within the first few hours, the evidence includes vomiting, diarrhea or hyperactivity. As time passes and there's increased absorption of the toxic substance, you'll see an increase in the dog's heart rate, which can cause arrhythmia, restlessness, hyperactivity, muscle twitching, increased urination or excessive panting.
This can lead to hyperthermia, muscle tremors, seizures, coma and even death.
