🍬 Can Dogs Eat Xylitol (Birch Sugar / Wood Sugar)?
🚫 FATAL / LETHAL TOXINVeterinary Quick Verdict
EXTREMELY DEADLY: Triggers massive insulin dump, hypoglycemic shock, and liver necrosis.
Health Overview & Veterinary Analysis
Xylitol (frequently rebranded as Birch Sugar, Wood Sugar, or Birch Extract) is 100x more toxic to dogs than chocolate. In dogs, xylitol tricks the pancreas into releasing massive amounts of insulin within 10 to 60 minutes. This causes precipitous, life-threatening hypoglycemia (blood sugar collapse), followed by acute, irreversible hepatic (liver) failure.
Massive rapid insulin release causing profound hypoglycemia and hepatic cellular destruction.
