Hypoglycemia (Especially in Puppies) in Dogs and Cats

Hypoglycemia (low blood glucose)

A drop in blood sugar to dangerously low levels, depriving the body — especially the brain — of the energy it needs to function. Particularly common and dangerous in young puppies, toy breeds, and neonates, whose bodies haven’t yet developed the ability to store and regulate glucose effectively.

Symptoms

Weakness or lethargy
Trembling or muscle tremors
Loss of coordination, wobbliness, or a “drunken” gait
Seizures
Fainting or collapse
In severe cases, coma

Causes

Immature liver and limited glycogen (energy) stores in very young or toy-breed puppies
Fasting, missed meals, or a cold environment, which increases energy demand
Underlying conditions such as a portosystemic (liver) shunt, intestinal parasites, or infections
In adult dogs, insulin overdose (in diabetic pets), Addison’s disease, pancreatic tumors, or severe liver disease

Treatments

Immediate action if hypoglycemia is suspected: rubbing a small amount of Karo syrup or honey on the gums, then seeking emergency veterinary care right away
IV dextrose (glucose) administration for a rapid, safe correction of blood sugar
Frequent, small, high-quality meals for at-risk puppies and toy breeds to help maintain stable glucose levels
Identifying and treating any underlying cause to prevent recurrence

This condition is common in the following Dogs & Cats
