This is a central nervous system disorder caused by low blood sugar. It occurs mainly in Toy Breeds, between six and twelve weeks of age. Often it is precipitated by stress. The signs are those of listlessness and depression. They are followed by muscular weakness, tremors (especially in the facial muscles) and later, convulsions, coma and death. The entire sequence is not always seen. The dog may simply appear to be depressed, or he may be weak, wobbly, jerky and may go into a coma.
Hypoglycemia can occur without warning, when a puppy is placed into a new home, or while being shipped. Might appear after a puppy misses a meal, chills, becomes exhausted from too much playing, or has a digestive upset. These upsets place an added strain on the energy reserves of the liver and bring on symptoms (if the dog is susceptable).
Puppies who are weaned on rice and hamburger are more likely to develop hypoglycemia. Their diet is deficient in certain ingredients needed to sustain the liver. A similar condition occurs in adult hunting dogs, usually when hunting. Care should be taken, to feed these dogs before hunting and to increase the protein in their diet.
Treatment
Treatment is directed at restoring blood levels of glucose. Beginning at once. Prolonged or repeated attacks can cause permanent damage to the brain. If the puppy is awake give him Karo Syrup, honey or sugar in water by mouth. He will begin to improve within 30 minutes. When he is unconscious, he will have to be given a Dextrose solution intravenously. It may be necessary to treat for swelling of the brain. A veterinarian should be called at once.
Prevent recurrant attacks by feeding high quality kibble diet, and add to it syrup, sugar or honey. See that the puppy eats and drinks regularly. Don't assume that he is eating or drinking. Owners of Toy puppies should not overtire them or allow them to chill.
