The dog’s body absorbs xylitol rapidly, causing its level in the blood to spike.
The pancreas responds by secreting massive amounts of insulin which leads to severely low blood sugar. It takes only a tiny amount of Xylitol to result in a life-threatening situation.
Potential symptoms of xylitol poisoning in dogs include:
- vomiting
- diarrhea
- abdominal pain
- loss of appetite
- abnormal mentation
- jaundice

Thank you, Carol Bryant, for sharing Boomer’s story.

Boomer’s story
Boomer is a dog who gets into things and eats items he shouldn’t.
He is “too smart for his own good.” Boomer opens doors and drawers by himself. He pulls things off counters, and nothing lower than 5 feet is safe from Boomer.
Xylitol poisoning?
Xylitol poisoning is not something Boomer’s mom ever knew about.
I have learned not to leave treats within reach. I also keep purses zipped and up high from prying eyes and paws. Boomer’s mom can relate and she hopes her recent near-tragedy helps other dog moms and dads.
“I had a friend in town for the weekend, and we went out to dinner and the symphony to celebrate me buying a new house and her accepting a new job and moving to Kansas City,” Boomer’s mom shares. “We left for about 5 hours. So I decided (stupidly) that I would just let Boomer stay out and be free while we were gone.”
What could he possibly do in a few hours, Boomer’s mom thought to herself.
After all, she put everything out of his reach.
What has Boomer eaten?
When she arrived home at 10:30 that night, she saw remnants of something all over the floor. Boomer broke into two containers of Ice Breakers Ice Cube gum and broke the plastic to get the gum out. The gum was left on the kitchen island in a bag from the store.
Boomer gets sick
Boomer had vomited and began drinking massive amounts of water.
He kept begging his mom for water and kicking his bowls around. Finally, something made her Google “My dog ate Ice Breakers gum.” What she read shook her to the core. Immediately, she rushed Boomer to the emergency vet.
Xylitol is one of the ingredients in Ice Breakers (and other sugar-free) products.
At the emergency hospital
The vet explained that even a tiny amount could be lethal. Boomr ingested 40 pieces. His prognosis was very poor. The Xylitol had time to travel to Boomer’s liver, and he was in danger of liver failure.
“Boomer needed an IV solution with glucose to try to even out his glucose levels and a liver protectant,” Boomer’s mom recalls. “She also said they needed to do a plasma transfusion to improve his clotting time.”
He began with Vitamin K injections, a glucose solution, and a liver-protecting drug. They wanted to flush his system out and hope the liver could start healing itself. Boomer was hospitalized from Thursday through Monday and began to show improvement.
Boomer almost died
Three nights of treatment cost Boomer’s mom over $2,500, and she nearly lost her dog to Xylitol poisoning.
“Everyone knows chocolate, grapes, raisins, etc., are toxic to dogs. So why don’t we know about Xylitol,” she wonders. “I vaguely remember hearing the word but never knew what it was in.
Surprisingly, it’s in quite a few things. Gum, mints, candy, toothpaste, mouthwash, OTC drugs, chewable vitamins, and more. Even athletic clothing!”
PetMD has an article about Xylitol toxicity, which we encourage all pet parents to read.
Boomer’s veterinarian revealed that there had been a considerable increase in Xylitol ingestion over the past year at their practice.
Preventing xylitol poisoning in your dog
What can you do to prevent Xylitol poisoning in your dog?
Read the labels carefully. Anything sugar-free should be avoided. Check if Xylitol is contained in any products you purchase. Keep them from your dog’s path, access, or counter surfing.
Companies are not warning pet parents, for the most part, that Xylitol can be fatal to dogs.
If you must purchase items containing Xylitol, hide them far from a dog’s reach. In our household, we rarely, if ever, purchase Xylitol-containing items.
Boomer was able to celebrate the holidays with his family.
