Important information about hypoglycemia:

First off, if you are planning on getting a chihuahua puppy, before the day your pup comes home, go to your vet  and buy a tube of Nutri-cal, (or "Nutri-stat" or "Vitacal") or order it online .  This may save your pup's life. 

Hypoglycemia means low blood sugar.  It can occur if a puppy has gone too long between meals, has gotten chilled or is stressed.  It is common in small breed puppies and is Life threatening- your puppy could die if not treated for it quickly.

A chihuahua puppy should always have access to food and must be monitored to make sure that he/she is eating.  I recommend feeding small meals every 4 hours and leaving quality  kibble out for in between meals and while you are sleeping.  Make absolutely sure that the pup knows where the kibble is and that he/she will actually eat it. 

The puppy should always be kept warm, just like you would with a human baby, and should be watched closely after periods of stress, such as the first day in a new home, shipping, or first trip to the vet, and after periods of prolonged activity.

Here are some signs of hypoglycemia:

weakness, listlessness, uncoordinated-                                                                     

(acting as if drunk),                                                                                                

blue or gray tinge to the ears, gums, or skin,                                                              

cold to the touch, confusion, disorientation, unusual drowsiness.

Left untreated, the dog may go into seizures and/or unconsciousness  and may die.     

Treatment:

If you see any of the above signs, FIRST, administer a supplement such as nutri-cal (preferable), corn syrup or sugar-  (dab it on the pup's gums and/or squirt under tongue).  THEN feed a protein-rich food, such as chicken baby food or grain free canned food. If symptoms do not improve immediately,  CALL YOUR VET.    If your pup perks right up and seems just fine after receiving the nutri-cal or other sugar source plus protein food, closely monitor him/ her.

Do NOT  put sugar in your chihuahua's drinking water.  This will not prevent low blood sugar,  and could even cause the blood sugar to spike, then drop, creating the very condition you are trying to prevent.
