Dogs can eat bread, but only in moderation and only plain, fully baked bread without harmful ingredients. Small amounts of plain white or brown bread are generally safe as an occasional treat. However, bread has little nutritional value for dogs and should not be a regular part of their diet. It's important to avoid bread containing toxic ingredients such as nuts (especially macadamia nuts), garlic, onions, chocolate, raisins, or artificial sweeteners like xylitol. Raw bread dough or sourdough starter is dangerous because it can expand in the stomach and cause serious health issues. Overfeeding bread can lead to obesity, stomach upset, vomiting, and diarrhea. Always consult a vet if unsure or if your dog has allergies.
