Hypoglycemia tends to be a problem seen most often in toy breed puppies. Hypoglycemia is the medical term for low blood sugar. Table sugar, or sucrose, is made up of two simple sugars, glucose and fructose, and can be broken down rapidly after eating.
All sugars are carbohydrates.
The body uses glucose as its primary energy source. The brain, however, is completely dependent upon glucose to function. If the glucose in the blood is lower than normal, the brain function is the first to show signs. In dogs, these signs may be seen as weakness, behavior changes, confusion, wobbly gait, or even seizures. In fact, in young dogs who have had what may appear to be an epileptic seizure, low blood sugar is generally ruled out before a diagnosis of epilepsy is made.
