Can Dogs Eat Peanut Butter? XYLITOL Warning Guide
Information synthesized from: FDA, Pet Poison Helpline, ASPCA Animal Poison Control, Preventive Vet
🚨 CRITICAL WARNING: CHECK FOR XYLITOL
⚠️ DEADLY ARTIFICIAL SWEETENER
Many peanut butter brands now contain XYLITOL - an artificial sweetener that is EXTREMELY TOXIC to dogs. Even a small amount causes life-threatening hypoglycemia within 15-30 minutes and liver failure within 12-24 hours.
XYLITOL TOXICITY:
- Toxic Dose: 0.1g per kg body weight (0.045g/lb)
- Lethal Dose: 0.5-1.0g per kg causes liver failure
- Symptoms: 15-30 minutes (low blood sugar), 12-72 hours (liver damage)
- Fatality Rate: HIGH if untreated

- ✅ Check ingredients for xylitol, birch sugar, E967
- ✅ Avoid "sugar-free," "low-sugar," "keto," "diabetic-friendly" labels
