Xylitol (gum, sugar-free sweets)

Applies to: Dog

Triggers insulin release → severe hypoglycaemia and possible liver failure in dogs.

Possible symptoms

Vomiting, weakness, tremors, seizures, collapse.

What to do

Emergency NOW. Bring the packaging if possible.

Why it is a problem

Xylitol is a sweetener found in some chewing gum, sweets, baked goods, toothpaste, peanut butter and sugar-free products. In dogs it can cause a rapid drop in blood sugar and, at higher amounts, liver damage. It is a true emergency because symptoms can begin quickly.

What a vet may do

Contact a vet immediately, taking the packaging. Treatment can include monitoring and supporting blood sugar and liver values over a period of days.

How to prevent it

Check labels on anything sugar-free, particularly peanut butter, and keep gum, bags and handbags out of reach.

Poisoning or emergency. PatiTools is not an emergency service. If signs are serious, go or call now.
