Toy breeds are prone to a condition called HypoGlycemia or Low Blood Sugar. This condition is not a disease or an illness it is a symptom. The result of too low glucose in the bloodstream.. Glucose feeds the brain and muscles. It is the fuel for the body. When the levels get low then the puppy becomes lethargic and can have a seizure. It can be a life threatening condition if not treat fast and appropriately. If your puppy is hypoglycemic he will not eat. Getting his blood sugar up with karo or nutrical will trigger him to eat.
You will need to keep karo syrup or nutrical on hand. Should you think you puppy is hypoglycemic then give him 2cc of Karo syrup or some nutri cal.
