[Food] Bread [Toxic?] Safe, but not recommended [Why?] 
Can you give your dog bread? Technically it's not toxic, but there is little nutritional value to a dog in bread. Feeding bread regularly is not a good idea. If a dog eats a large amount of bread it can cause stomach upset. It's important to note that bread dough (i.e. uncooked) can be quite toxic to dogs (see below)
