Question: are mints poisonous to dogs?
Answer: Xylitol may cause a life-threatening drop in blood sugar as well as causing liver damage to dogs. ... Chewing gums and breath mints typically contain 0.22-1.0 gram of xylitol per piece of gum or per mint. Thus, to achieve a potentially toxic dose, a 10 pound dog would only have to eat one piece of gum!
