In some respects, bringing your new Chihuahua puppy home is like bringing home a tiny newborn human baby. Most important! Chihuahuas, like many other toy breeds, may be susceptible to a form of low blood sugar called hypoglycemia.
You probably won’t experience low blood sugar (with your particular puppy) but, in the event that you do, it is an emergency. Small dogs, especially Chihuahuas, have a very small fat reserve around the liver. When they get stressed for some reason (like going to a new home), or if they play too hard (using a lot of energy), or miss a meal, the fat reserve is used up and the body will begin to draw upon the blood sugar for energy. If this condition is left unchecked the dog will grow progressively weaker until it falls into a coma and eventually dies. The good news is that this condition is easily arrested and puppies that do experience hypoglycemia will usually outgrow it by 16 weeks of age. Your goal, as a new owner, should be to keep the puppy's stress level as low as possible during the critical period.
Often the most dangerous period is between six and ten weeks of age. During that time the puppy is weaned away from the dam, wormed, vaccinated, bathed, his toenails are trimmed, and sometimes he is sold into a new environment. Also, the immunity that a puppy gets from the mother’s first milk will drop off somewhere around the ninth week, and that will increase his vulnerability to virus and bacteria. All together, these factors contribute to a very stressful time for the little dog. Some puppies breeze right through it and others have problems.
Signs of hypoglycemia vary; usually the dog will get a sad forlorn look on its face, then it will become inactive, eventually staggering, falling down, or just laying down, followed by what looks like sleep. This sleeplike condition will turn into a form of tooth-clenching seizures and spasms, followed by a comatose condition, and, eventually, death. Not all symptoms may be seen at any one time so watch for any lethargic behavior or lack of coordination. If your puppy seems too sleepy, wake him up, stand him up and make sure he stands and can walk normally. If he lies back down, falls, or staggers, then get some sugar into him. If you are unsure of how to proceed then call your breeder and/or your veterinarian.
Hypoglycemia is seen most often in smaller specimens of Chihuahua puppy, but I caution all new owners to watch your puppy carefully until he is at least 16 weeks of age. While hypoglycemia could be a potential problem to any puppy, given the proper circumstances, it can be easily treated.
Sugar in the drinking water, pancake syrup, nutri-cal vitamin paste, nutristat, (generic nutri-cal and less expensive), kids sugarcoated breakfast foods will help restore lost blood sugar. In severe cases a veterinarian may have to inject a glucose solution into the dog’s bloodstream. This occurs usually in cases where the dog is unconscious and unable to swallow. The injection is usually made into a major blood vein such as the jugular vein in the throat.
One good idea is to make sure your dog eats just prior to his being out of your sight for any extended period of time. You can also boost him with sugar in some form (except candy) before you leave him. You must make sure to leave some food available so the dog can eat while you’re away. Some Chihuahuas are nibblers who eat very slowly and some are down right finicky so take that into account and leave him with nutrition that is tempting enough that he will eat something while you are away from him.
Stress can be a real problem to some Chihuahuas. Common sources for high stress are, being sold and taken to a new environment, a temporarily depressed immune system caused by vaccinations, a radical and sudden change of diet, being terribly frightened by something. Some things humans might consider being of little consequence, such as trimming his toenails or giving him a bath, can be terrifying to your little dog. Like people, some dogs will handle stress better than others. The point being that you should minimize stress in your puppy’s life whenever possible and keep him eating to offset any possible bouts of stress-induced hypoglycemia.
