sorbitol

Sweetener

Sorbitol is the sugar alcohol that ISN'T xylitol — a distinction worth a page, because one is a mild humectant and the other kills dogs.

Also appears on labels as: e420

What it is

A sugar alcohol used as humectant and mild sweetener in semi-moist treats and dental products. Sugar alcohols vary wildly by species tolerance, and the family name causes dangerous confusion: sorbitol is the tame one; XYLITOL — common in sugar-free gum, mints, some peanut butters — triggers massive insulin release in dogs, with life-threatening hypoglycemia and liver failure at small doses.

Why it's in pet food

Moisture retention and gentle sweetness without sucrose. Pet-food formulators use sorbitol precisely because it's the boring member of its family; xylitol does not appear in pet food, only in human products your dog might raid.

How Bowlmark scores it

Scores are deterministic math over the printed label — the rules below apply to every product identically, and nothing estimates or fills in a blank.

Neutral in the engine: sorbitol is not on the sugars deduction list (chemically an alcohol, not a sugar) and carries no flag. The safety freight on this page points at the pantry, not the pet-food label: sugar-free HUMAN products are the xylitol vector — check gum, mints, and peanut butter before sharing, and treat suspected xylitol ingestion as an emergency, immediately.

For dogs

Sorbitol at label doses: fine, mildly laxative in excess. Xylitol at almost any dose: an emergency — vomiting, weakness, collapse within an hour; go now, don't watch and wait.

For cats

Cats show less xylitol sensitivity than dogs in the literature, but nothing about sugar-free human products belongs in a cat either.
