Toy-breed dogs are not only at risk for hypoglycemia, they can die from the low blood sugar disorder if they do not receive prompt treatment.
When a dog’s blood sugar, or glucose, level drops, it can affect neurological function. Disorientation, tremors and coma may occur. Normally, hormones stimulate the breakdown of stored glycogen to supply the brain and other tissues with fuel. In toy breeds, this process may not happen fast enough, and hypoglycemia results.
