Why do dogs die when they eat chocolate

Chocolate is high in fat, as well as caffeine and cocoa, two different types of stimulants that affect the dog’s central nervous system and heart muscle, the dog’s heart cannot afford such a burden and can suffer cardiac arrest and burst blood vessels leading to death. Chocolate should actually refer to dark chocolate, cocoa content of more than 35% of the dark chocolate. People in eating more pure dark chocolate will have accelerated blood, heart speed feeling, this is the role of caffeine, and the dog’s heart can not afford such a burden, cardiac arrest, blood vessels burst, this should be the biggest reason why dogs can not eat chocolate. The right point is that dogs can not eat natural cocoa powder and other foods that increase the burden on the heart, ordinary chocolate bars, chocolate cookies eat is nothing, because basically nothing cocoa content in fact, chocolate poisoning and the type of chocolate and the size of the dog has a direct relationship, the more pure chocolate, the smaller the dog, the greater the chance of poisoning. The methylxanthine contained in chocolate, which is also the main component of theobromine and caffeine, is the source of the danger of chocolate. In terms of theobromine and caffeine, the lowest dose that can kill a dog is 100-200 mg/kg. theobromine in chocolate is the main factor in dog poisoning, with 115 mg of theobromine per kilogram of chocolate likely to kill a dog, while the average pure chocolate contains about 400 mg of theobromine per 29.6 grams per ounce. In other words, a one-kilogram dog eating 9 grams of pure chocolate could lead to death. And now more and more people like to have small dogs, such dogs eat 20 to 30 grams of chocolate in just a blink of an eye (most of the chocolates bought in the market are 60 to 80 grams packaged), so the chance of their poisoning is really high. The symptoms of chocolate poisoning are: vomiting, dysentery, frequent urination, restlessness, hyperactivity, and rapid heartbeat and breathing. Severe cases can also lead to ataxic walking instability, cyanosis, cardiac arrhythmia, seizures, and even ultimate death due to loss of cardiovascular function. Treatment of chocolate poisoning is based on pharmacological support therapy, and in severe cases bladder catheterization is implemented to avoid double absorption of toxins through the urethral mucosa.
