Dogs Can Eat Plain, White Bread in Moderation
Dogs are unlikely to get sick if you give them small pieces of plain, white bread from time to time. That said, there isn’t really a good reason to let them each white bread given the lack of nutrients. You also need to be aware that some dogs are allergic to wheat and grain, meaning foods like white bread would be an absolute no-go for some dogs.
If you do plan on letting your dog a few pieces of white bread then make sure it doesn’t contain any harmful ingredients. For example, some white breads may contain artificial sweeteners like xylitol, which are toxic to dogs. Other types of white bread may be heavy in ingredients like butter, which may cause problems with your dog’s stomach if it is ingested in large amounts.
Ideally, if there’s no good reason to feed your dog a certain food then don’t do it. Some types of white bread may also contain a relatively high amount of calories, which will only cause additional weight problems for dogs.
