HYPOGLYCEMIA-- If you are going to become a toy dog owner you will want to familiarize yourself to the symptoms of hypoglycemia.  Hypoglycemia is when the blood sugar levels (glucose) fall well below normal.  Glucose is what the body uses as fuel and is necessary for the brain tissue and muscles to function.  Hypoglycemia is often seen in toy breeds, and frequently in young toy puppies.   It can cause your puppy to become confused, disoriented, drowsy, have the shivers, stagger about, collapse, fall into a coma, or have seizures.  

Typical signs are listlessness, depression, staggering gait, muscular weakness, and tremors -- especially of the face.  Puppies with a severe drop in the blood sugar develop seizures or become stuperous and go into a coma.  Some puppies may only exhibit weakness or a wobbly gait, and occasionally a puppy that seemed just fine is found in a coma. 

Most of the time the symptoms can be controlled by eating, or by giving some glucose such as honey water to the puppy. Nutracal is an important thing to keep around.  If not treated, Hypoglycemia can result in death.
