What Is Caffeine?

Caffeine is a stimulant drug found naturally in some plants, including coffee beans, tea leaves, and cocoa beans. It is also found in some medications, energy drinks, and certain foods. Caffeine is a central nervous system stimulant, which means it increases alertness and energy levels. It is also a diuretic, meaning it can increase urination.

How Much Caffeine Is Too Much For Dogs?

The exact amount of caffeine that is too much for a dog varies depending on the size and breed of the dog, as well as the strength of the caffeine. In general, however, experts advise that dogs should not consume more than 40 mg of caffeine per kilogram of body weight. For a small breed, such as a Chihuahua, this would be equivalent to about 2.5 mg of caffeine per pound of body weight.
