Red: toxic
No, chewing gum should never be eaten by dogs. Many sugar-free chewing gums are sweetened with xylitol, which the ASPCA says can cause low blood sugar and liver damage in dogs.
Why chewing gum is dangerous
According to the MSD Veterinary Manual, xylitol triggers a rapid, large release of insulin in dogs, causing blood sugar to fall. Signs can begin within 30 minutes, but with chewing gum they may take 12 to 18 hours to appear because the gum releases xylitol slowly. Typical signs include vomiting, weakness, staggering, lethargy and seizures. Liver damage often becomes apparent only after 24 to 48 hours. According to Pet Poison Helpline, xylitol content varies widely, even between flavours from the same brand.
What to keep in mind
- Do not leave chewing gum, peppermints or dental gum in jackets, handbags or on the coffee table.
- “Sugar-free” on the packaging is a warning sign: check the ingredients for xylitol.
- Watch out for discarded chewing gum on pavements.
What if your dog has eaten chewing gum?
Call your vet or an emergency veterinary service immediately, even if there are no signs. Be ready to explain which variety it was (ideally with the packaging), roughly how many pieces were eaten, when it happened and how much your dog weighs. Do not induce vomiting yourself. According to MSD, blood sugar can fall so quickly that this should only be done under veterinary supervision.
If you suspect poisoning, contact your vet or an emergency veterinary service immediately.
