The normal fasting blood glucose range for a dog is between 72 to 108 mg/dL.
- A blood sugar reading below 70 mg/dL is considered hypoglycemia (low blood sugar) and can be life-threatening.
- A blood sugar reading above 140 mg/dL is considered hyperglycemia (high blood sugar).
- A blood sugar level over 250 mg/DL needs immediate veterinary attention.
Hypoglycemia and hyperglycemia can be a sign of diabetes, which is a common medical condition in dogs. If your dog is diabetic, you will need to check its blood sugar levels on a regular basis. Always refer to your veterinarian prior to and during any changes to get the best advice for your dogs condition.
