We’ve all heard that chocolate is toxic to dogs – but how toxic is it and why?

Why is Chocolate Toxic to Dogs?
Theobromine, a naturally occurring stimulant found in chocolate is responsible for a toxic reaction. Theobromine occurs naturally in cocoa beans which is present in all chocolate products. Dogs do not metabolize theobromine as fast as humans do – therefore, it can cause a serious reaction on their heart, kidneys, and central nervous system.

How Much Chocolate is Too Much for Dogs?
The amount of theobromine in chocolate depends on the kind of chocolate and the serving size. Baking chocolate contains far more thebromine than milk chocolate. On average, baking chocolate contains 390mg thebromine per ounce and milk chocolate contains 44mg thebromine per ounce.

To determine “how much is too much?” can be difficult since many factors such as the dog’s health, age and size are involved. However, it is estimated that toxic reactions can occur with the theobromine ingestion of 45mg per pound of a dog’s body weight.

Signs of Chocolate Poisoning
Common signs of chocolate poisoning include (but not limited to) vomiting, diarrhea, hyperactivity, restlessness, excessive panting, muscle twitching, and increased heart rate. Seizures, coma and even death can occur with chocolate poisoning.

If you suspect your dog has ingested chocolate, seek veterinary attention IMMEDIATELY!
