Hypoglycemia is an abnormally low level of glucose in the bloodstream. It's not unusual for it to strike puppies, particularly toy breeds, between 6 and 12 weeks of age. Puppies are vulnerable because their ability to regulate their blood glucose levels aren't fully developed and they have high glucose requirements.
A puppy uses a lot of energy during the course of his busy day. If Willie misses a meal, plays too hard or gets cold, he can suddenly develop an episode of hypoglycemia. In addition to blurred vision, or even sudden blindness, a hypoglycemic young pup can develop tremors or a staggering gate, and act depressed or listless. In extreme cases, a puppy who was previously healthy and active can suddenly slip into a coma.
If Willie experiences any of the symptoms for hypoglycemia, rub a bit of corn syrup, honey or sugar water on his gums and get him to the vet. Puppies suffering from hypoglycemia tend to have a favorable prognosis. If Willie suffers repeated episodes, he should be tested for underlying problems.
