Are dogs allergic to bread?
Many believe it's instinctual behavior, harkening back to the days when your dog's wild ancestors would mask their scent to help them sneak up on their prey.
Wolves, for example, have been observed rolling in animal carcasses or the droppings of plant-eating animals, to cover up their own smell during the hunt.
Safe: Some Vegetables.
Your dog can have a healthy snack of carrot sticks, green beans, cucumber slices, or zucchini slices.
Even a plain baked potato is OK.
Don't let your dog eat any raw potatoes or any potato plants from your pantry or garden.
Plain white and wheat bread is generally safe for dogs to eat, provided they don't have any allergies, and it usually does not cause any stomach upset.
Feeding your dog bread as a treat now and then won't hurt her, as long as she is also fed a complete and balanced diet and gets plenty of exercise.
