Bread is safe for dogs
Bread is safe to feed to your dog. However, it should only be fed to your dog occasionally as it has very little nutritional value and is high in carbohydrates. Plain white bread, whole-wheat, and whole-grain breads are generally safe. Breads such as rye and pumpernickel are also safe unless your dog is sensitive to certain grains.
Bread with added ingredients requires extra caution. Some ingredients, such as garlic, onion, macadamia nuts, chocolate, and raisins, can be toxic to dogs and any bread containing these ingredients needs to be avoided.
Bread dough is also toxic to dogs as it will continue to rise in a dog’s stomach if it is eaten. The expanding dough can cause bloat and the fermenting yeast releases ethanol which can cause alcohol poisoning.
