Xylitol, a sugar alcohol, is a popular sugar substitute(40% fewer calories than sugar).
It is found today in many products including; chewing gums,toothpastes, and other oral care products. Xylitol is not used by the bug most responsible for dental decay (S. mutans) hence its popularity in dental products.
Xylitol is slowly absorbed by humans. This minimizes human side effects. On the contrary dogs experience a fast and massive increase in insulin after ingesting small amounts.
A dog that eats 3-4 pieces of gum is at risk for liver necrosis and failure.
Any amount of xylitol is considered toxic for dogs.
