                                Hypoglycemia

 

Hypoglycemia or low blood sugar is a possible problem with all toy breed puppies. Veterinarians unfamiliar with toys often mis-diagnose the condition as viral hepatitis or encephalitis. As a toy breeder or pet owner, it is important to recognize the symptoms of hypoglycemia and know how to treat it. Hypoglycemia is easily treatable in the early stages, but fatal if allowed to progress. Many puppies are lost needlessly to hypoglycemia because of ignorance on the part of their owner or veterinarian.

The first sign of hypoglycemia is the puppy slowing down and then acting listless. The puppy will then begin to tremble or shiver. This is a reaction caused as the brain is starved for glucose. The trembling is followed by a blank stare and the puppy lying on his side. He may also experience convulsions. After a time, the puppy will become comatose. His body will be limp, lifeless, and the tongue and gums will be a grayish/blue color. The body temperature will be subnormal. The puppy may even appear to be dead.

If caught in the early stages, treatment is simple. Rub Nutri-Cal (Caro syrup (Corn Syrup) will do if you have no Nutri-Cal) on the puppy's gums, under the tongue, and on the roof of the mouth. (Caution: do not use honey.) Get a heating pad or heating blanket and slowly warm the puppy to proper body temperature. If the puppy responds, all is well. Feed a quality canned food right away (you may want to mix it with egg yolk) and then monitor the puppy to be sure that the condition does not recur. Be sure to eliminate the stress that caused the episode if at all possible.

It is important to understand that just because a puppy has an episode of hypoglycemia, it does not mean that the puppy is truly "hypoglycemic." True hypoglycemia is a chronic condition caused by overproduction of insulin by the pancreas. Even though the pancreas may normally function properly, toy puppies can still have an isolated hypoglycemic incident in reaction to stress. Hypoglycemic incidents are almost always preceded by a stress of some kind. Some examples of common stresses include: weaning, teething, vaccinations, a change in environment, shipping, over-handling, cold temperatures, intestinal parasites, infections, anorexia, etc. Many puppies simply play too hard and stress their system or forget to eat. I have heard of young males experiencing hypoglycemia when a female in heat is around. They become so worked up over the female that they do not eat and their blood sugar drops.

Tiny dogs often do not have the fat reserves to supply adequate glucose in times of stress or when they do not eat regularly. Hypoglycemia most often occurs when the puppy has not eaten for several hours. This is not always the case, however. A puppy can have eaten recently and still show sings of hypoglycemia if his system is stressed and the food has not been digested and assimilated. It is important to "free feed" toy puppies a high quality food. Toy puppies simply have too high of an energy level to be restricted to scheduled feedings. Most do fine if switched to scheduled feedings when they reach adulthood, but they must have access to food and water at all times when they are puppies. If you like to give your puppy canned food, you can schedule the feeding of the canned, but allow access to kibble at all times.

A summary of important reminders is as follows:
1) Always keep Nutri-Cal or Caro (Corn Syrup) on hand. This is the quickest way to revive a hypoglycemic puppy.
2) If you ever see your puppy becoming listless, or laying on his side and acting unresponsive IMMEDIATELY rub Nutri-Cal or Caro on his gums, under his tongue, and on the roof of the mouth. Slowly warm him to normal body temperature with a heating pad. Feed him as soon as he responds. Call your veterinarian if the puppy does not quickly respond.
3) Keep your puppy from chilling, free of parasites, and minimize stress.
4) See that your puppy eats often and maintains a proper body weight.
5) Do not over-handle your puppy. Be sure to allow him rest time and alone time. Like all babies, puppies need to have a regular schedule of rest, meals, play and potty.
