Results are calculated in your browser. Always double-check before administering and use your clinical judgement.
How it is calculated
Xylitol (mg/kg) = grams ingested × 1000 ÷ body weight (kg).
Doses greater than approximately 100 mg/kg have been associated with hypoglycaemia in dogs; some dogs ingesting > 500 mg/kg may develop severe hepatic insufficiency or failure [1].
Worked example
2 g in a 10 kg dog = 200 mg/kg.
