How much xylitol is toxic?
The toxic dose is about 0.1 grams per kilogram of body weight (about 0.045 grams per pound). Most gums have 0.3-0.4 grams of xylitol per stick, so a 10 pound dog could be poisoned with as little as ½ a stick of gum. The dose that causes liver damage is 1 gram per kilogram of body weight (about 10 times that of hypoglycemia), so the 10 pound dog would have to eat a package of unopened gum. Trident regular gum has 0.22 grams of xylitol per piece, Trident Xtra care had 0.28 grams per piece and Trident stride has 0.21 grams per piece.
