Dog Xylitol (Birch Sugar) Toxicity: Hypoglycemia & ER Triage
Clinical Verdict: CRITICALLY FATAL (Rapid-Onset Emergency)
Dogs CANNOT consume xylitol (often labeled as birch sugar or wood sugar). In dogs, it stimulates an explosive insulin surge, triggering profound hypoglycemia and acute hepatic necrosis.
Toxic Mechanism & Chemical Agent
- Toxic Agent: Xylitol (1,4-anhydro-D-xylitol / Birch Sugar)
- Mechanism of Action: In canines, xylitol is absorbed rapidly and causes an immediate, dose-dependent release of insulin up to 6 times greater than an equivalent dose of glucose, collapsing systemic blood sugar within 30 to 60 minutes.
Clinical Signs & Staged Timeline
- Onset Time: Hypoglycemia within 30 to 60 minutes; Acute hepatic failure within 12 to 24 hours.
- Primary Symptoms: Vomiting, acute ataxia (drunken staggering), extreme lethargy, collapse, hypocalcemic tremors, seizures, and severe jaundice.
Emergency Triage Protocol
IMMEDIATE ER VISIT (Zero Delay)
Transport immediately to an emergency hospital. If the dog is already weak, lethargic, or disoriented, DO NOT induce vomiting at home (risk of aspiration). Immediate IV dextrose bolus and continuous glucose infusion are required.
Strict Rule S1 Warning
NEVER induce vomiting at home using hydrogen peroxide without direct instruction from a DVM. Inappropriate emesis can cause fatal aspiration pneumonia. Always seek professional veterinary diagnosis.
