How much glucose should be dripped into a dog? - briefly
The amount of glucose to be administered intravenously to a dog depends on the dog's weight and the severity of the hypoglycemia. A common starting dose is 0.5-1 gram per kilogram of body weight, given over 15-30 minutes.
How much glucose should be dripped into a dog? - in detail
Determining the appropriate amount of glucose to administer intravenously to a dog requires careful consideration of several factors, including the dog's body weight, the severity of hypoglycemia (low blood sugar), and any underlying medical conditions. Here is a detailed guide on how to calculate and administer glucose drips safely:
-
Assessment of Hypoglycemia: The first step in managing hypoglycemia is to confirm the low blood sugar level through diagnostic testing. Typically, blood glucose levels below 70 mg/dL (3.9 mmol/L) are considered hypoglycemic.
-
Calculation of Glucose Dose: The standard dose for treating hypoglycemia in dogs is 0.5-1 g/kg of dextrose (glucose). This can be administered as a bolus initially, followed by a continuous infusion to maintain stable blood sugar levels.
-
Bolus Dose: For the initial treatment, a bolus of 0.25-0.5 g/kg of dextrose 50% (D50) can be administered intravenously over 3-5 minutes. This rapid infusion helps to quickly raise blood glucose levels and prevent further deterioration.
-
Continuous Infusion: After the bolus, a continuous infusion of dextrose is typically started at a rate of 0.25-1 g/kg/hr. The exact rate will depend on the dog's response to treatment and ongoing monitoring of blood glucose levels.

Monitoring Blood Glucose Levels: It is crucial to monitor blood glucose levels closely during the administration of glucose drips. Frequent measurements (every 15-30 minutes) are necessary to ensure that the dog's blood sugar is returning to a normal range (70-120 mg/dL or 3.9-6.7 mmol/L) and to adjust the infusion rate as needed.
-
Adjusting the Infusion Rate: Based on the results of blood glucose monitoring, the infusion rate may need to be adjusted. If blood sugar levels are not rising appropriately or if they begin to drop again, the infusion rate can be increased. Conversely, if blood sugar levels become too high (hyperglycemia), the infusion rate should be decreased or stopped temporarily to prevent complications.
-
Transition to Oral Glucose: Once the dog's condition has stabilized and blood glucose levels are within the normal range, the intravenous glucose drip can be gradually tapered off. The dog should then be transitioned to oral glucose sources, such as a high-carbohydrate diet or sugar water, to maintain stable blood sugar levels.
-
Underlying Causes: It is important to identify and address the underlying cause of hypoglycemia in dogs. Common causes include insulin overdose, liver disease, sepsis, and certain types of cancer. Treating the primary condition is essential for preventing recurrent episodes of hypoglycemia.
By following these guidelines, veterinary professionals can safely and effectively administer glucose drips to dogs with hypoglycemia, ensuring prompt resolution of low blood sugar levels and minimizing the risk of complications.
