Hypoglycemia (low blood sugar), is a disorder that occurs mainly in small breed puppies such as Chihuahuas between five and sixteen weeks of age. It is often precipitated by stress and can occur without warning. It may appear if your Chihuahua puppy misses a meal, is exposed to cold and catches a chill, becomes exhausted from playing, or has a digestive upset. These upsets place an added strain on its energy reserves and bring on the symptoms.

Hypoglycemia is a real threat to tiny Chihuahua puppies, so always watch your Chihuahua for tiredness or droopiness. The first signs are those of listlessness and depression. They are followed my muscular weakness, tremors, cunvulsions, coma, and even death. The puppy may appear depressed or may be weak, wobbly and jerky, or the puppy may be found in a coma.

If your puppy has any symptoms of Hypoglycemia you must act extremely fast. If the puppy is awake, give it Nutri-Cal, Corn syrup, or Caro syrup by mouth (we recommend Nutri-Cal). You should see signs of improvement within thirty minutes. If there is no improvement, then call your veterinarian immediately.

Prevent Hypoglycemia from happening by allowing only twenty minutes of play at a time followed by rest or sleep. Do not allow the puppy to overtire at first. Supervise your Chihuahua closely with children to make sure the puppy is getting enough rest. Keep the puppy warm (don’t let it become chilled). Your Chihuahua is a house dog and should not be living outdoors.

Prevent attacks by feeding a high quality kibble diet. We recommend Royal Canin puppy 33 up to 10-12 months, and Royal Canin Chihuahua 28 for Chihuahuas over 1 year. Other foods I’ve heard good things about are Eukanuba, Nutri Source or Eagle small breed puppy food. Ensure the puppy has food and water in front of him at all times, and that he is eating at least every six hours. You can give 1/2 a teaspoon of Nutri-Cal or syrup morning and night for the first couple of days after bringing your new puppy home to help prevent low blood sugar that can come with the stress and excitement of going to a new home.


- Always keep Nutri-Cal on hand. Substitutes are Corn or Caro syrup. (Dextrose given orally works best however it may be more difficult to find. Contact your veterinarian or vet supply store for Dextrose)

- If you ever see your puppy acting unresponsive IMMEDIATELY rub Nutri-Cal 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 your puppy does not quickly respond.

- Keep your puppy from chilling, free of parasites, and minimize stress.

- See that your puppy eats often and maintains a proper body weight. We recommend having food and water in front of your Chihuahua at all times.

- Do not over handle your Chihuahua puppy. Be sure to give him enough downtime to rest. Like all babies, Chihuahua puppies need to have a regular schedule of rest, meals, play, and potty.
