Pug dogs have often been described as multum in parvo, or much in little. Unfortunately, their small size can also make them susceptible to blood sugar problems, particularly when they are puppies. Although most pugs love to eat, they also can be very tenacious and may focus on one activity and forget to eat. This can cause dangerous fluctuations in their blood sugar levels.

Causes of Low Blood Sugar

Hypoglycemia or low blood sugar can develop quickly in small dogs. Pug puppies are prone to this due to their small size and boundless energy, which can cause them to become overly absorbed in a particular activity and miss a meal. Getting chilled or overheated can also trigger low blood sugar in a pug. They can also develop blood sugar problems from exhaustion from playing too hard. Puppies and smaller individuals experience these problems more frequently than full sized adults.

Symptoms of Low Blood Sugar

Symptoms of low blood sugar in a pug may not be noticed initially. The pug may become drowsy and unusually disinterested in activity. As the blood sugar continues to decrease, the pug may begin to jerk or have tremors. He may seem weak and unable to walk without wobbling. His neck may stiffen and turn his head to one side with his teeth clenched. If severe and untreated, low blood sugar in a pug can result in convulsions, coma and even death.

Treatment of Low Blood Sugar

Experts at PugCenter.com recommend treating your pug immediately if you notice low blood sugar symptoms. They suggest giving the pug a mixture of Karo syrup and water while you are in the process of contacting your veterinarian. Other nutritional supplements that contain glucose may also be helpful during this time. Use care not to administer the glucose in large amounts that could choke a dog that is having trouble swallowing.


Pug puppies and small adults have small stomachs and may need frequent feedings to keep enough glucose in their systems. Always contact your veterinarian immediately if you suspect that your pug has blood sugar problems or you see symptoms of unusual shaking, weakness or lethargy. If your pug has been diagnosed with low blood sugar issues, consult with your veterinarian to determine the proper maintenance diet to control the problem. Pay special attention to the fact that pugs are prone to weight gain, so you may have to work to balance the introduction of additional calories and adequate exercise.
