Can Dogs Eat Greek Yogurt? 🚨 Xylitol Warning & Probiotic Benefits
Information synthesized from: American Kennel Club, Purina, JustFoodforDogs
Quick Answer
✅ YES - Plain Greek Yogurt Safe (IF Xylitol-Free)
Dogs can safely eat plain, unsweetened Greek yogurt that is xylitol-free. Greek yogurt has double the protein (10g vs 5g) and lower lactose than regular yogurt, making it easier to digest. Rich in probiotics and calcium, it supports digestive health. However, NEVER feed yogurt containing xylitol - even small amounts cause liver failure.
According to veterinary sources, Greek yogurt is a healthier choice for dogs due to lower lactose content from the straining process.
