Hypoglycemia Yorkshire Terriers and many other toy breeds, due to their small size and rapid metabolism, are prone to a condition called, Hypoglycemia.  The smaller the puppy is the more accessible they are to hypoglycemia. Hypoglycemia is a condition that occurs when your puppy’s blood sugar level (glucose) falls below normal.  Glucose is what the body uses as fuel and is necessary for the brain tissue and muscles for function. Although it can be fatal, it is avoidable when equipped with the proper knowledge. Some symptoms are: * Lethargy * Loss of Appetite * Seizures * Vomiting      * Wobbly /Dizzy Puppy * Disorientation * Loss of conscientiousness * Trembling or Shaking (often mistaken as a cold  or nervousness)    What causes low blood sugar? Hypoglycemia most readily occurs in puppies under the age of 6 months of age though it is not unheard of in older dogs.  It seems to be related to the small size of a toy breeds’ immature liver while they are not yet full grown.  The threat usually resolves as the dog matures.         Your puppy’s blood sugar level can drop for many reasons.  It can be caused by a stressful situation by shipping, or a missed meal, being chilled, or even exhaustion from too much play. Puppy hypoglycemia can usually be overcome by feeding frequent meals, since Yorkies cannot eat a lot at one time, they literally run out of fuel quickly, a commercial puppy diet is recommended.  A nutritional supplement high in sugar, called Nutri-cal, can be used to keep your puppy’s blood sugar level normal.  Nutri-cal can be to stimulate a puppy refusing to eat.  It can be rubbed into the puppy’s gums for a more rapid result.   About 20 minutes later your puppy’s appetite will return.  Nutri-Cal can be purchased from your favorite, local pet store, or even from your veterinarian. Karo Syrup diluted in water is another alternative in keeping their sugar level up when they are stressed or simply having to much activity.
