Small Puppy Hypoglycemia: Angel’s Story
Hypoglycemia is a medical term for low blood sugar. Small breed puppies are extremely vulnerable to this life-threatening situation.
Symptoms of hypoglycemia include
- weakness
- lethargy
- sleepiness
- neurological signs
- twitching
- tremors
- seizures
- coma
Puppies can develop hypoglycemia from parasitic infestation or simply because of insufficient caloric intake and reserves. Glucose reserves are in the liver but tiny puppies’ liver is so small it cannot store enough. A long gap between meals is enough to cause a dangerous drop in blood sugar levels.

Angel’s story
Angel was a healthy, active Chihuahua puppy. She was born in a litter of three and had two healthy brothers. Her brothers were more assertive about food than Angel was and her human mom had to be careful to make sure Angel got the nutrition she needed.
Angel was also a fussy eater. The puppies were fed three times a day but Angel wouldn’t eat unless heavily encouraged.
Angel’s hypoglycemia
Every morning, when their human mom walked into the room, all three puppies would bounce to greet her. This time, however, the two boys rushed to visit but Angel remained curled up in the corner.
Was she just unusually sleepy?
Upon closer inspection, Angel’s mom observed that Angel was twitching and didn’t respond to nudging. It looks as if Angel was having some sort of seizure.
Immediately, Angel’s mom called their vet clinic and was on the way.
At the veterinarian
Ten minutes later, her mom carried Angel’s limp body to the clinic.
The veterinarian quickly examined Angel, drew some blood and started emergency treatment while waiting for results of the blood work.
The blood work confirmed his suspicion–Angel was suffering from hypoglycemia. Without prompt treatment, Angel would have died.
Angel received an IV glucose. Within minutes, she perked up and became interested in her surroundings. An hour later, Angel was ready to return home.
The puppies’ feeding regime was changed from three to six meals a day, including just before bed and early in the morning. Some puppies might even need to be fed every two hours.
As Angel grows up and her liver fully develops, she will have better glucose reserves to smooth out her blood sugar levels.
