Hypoglycemia is not a disease but rather an imbalance of energy expended versus nutrition (energy) stored in the body. A baby yorkie (Yorkshire Terrier) cannot eat very much at one time and has difficulty storing enough energy in the form of nutritional food to sustain a period of fasting or excessive activity. A tiny puppy can get hypoglycemia from too little proper food intake.

Symptoms: Yorkie may be tired or listless, staggering, have tremors, or even be unconscious. These symptoms can progress to seizure, coma, and even death. The progression of these symptoms can be slowed down or even halted by the intake of simple sugars.

Energy Reserves can be depleted by missing food or the yorkie not liking foods presented, becoming chilled (shivering takes energy) or becoming too tired from over-handlling or too much play.

A yorkie that is sick and has vomiting or diarrhea is much more susceptible to hypoglycemia. Stress such as caused by meeting strangers, going to a new home, or traveling can cause episodes. Anything that depletes energy reserves in your yorkie can cause the onset of symptoms.

Prevention: Hypoglycemia can be prevented with adequate and proper food and feeding practices. The owner cannot just plop down a bowl of food and walk away, but must make certain that the yorkie eats well, gets adequate rest, and is not overly stressed. A high quality food is also important and food supplements as needed. Please consult with your vet for a puppy food that has proper nutritional values. If you are an experienced breeder, you will already know what food works best for you and your yorkie.

Ideally a yorkie under 4 months old should have access to food constantly or at a minimum 4 times a day. Consult with your vet about how long touse puppy food, but we recommend until the Yorkshire Terrier is 9 months old.

NutriCal or other commercial glucose products are easily available and should be on hand for young puppies. A quarter-inch blob squeezed onto your finger and rubbed into the yorkie’s mouth morning and night will help assure adequate intake of energy. More can be given if symptoms are visible.


A yorkie with acute symptoms is in danger and should be given immediate sugar in the form of NutriCal, corn syrup or honey, which can be given with a syringe if your yorkie is conscious, or can be rubbed into the puppy’s tongue and gums if he is not. If the yorkie is in seizure or is unconscious, seek urgent help from vet after first rubbing a sugar product in it’s mouth. Your FIRST response should be replacement of blood glucose. GET SOME SUGAR INTO YOUR YORKIE SO THEY DO NOT DIE ON THE WAY TO THE VET, AND KEEP THEM WARM!
