Will peppers hurt dogs?
Dogs are mainly carnivores, so they don't need too many veggies in their meals.
High quantities of any vegetable, bell peppers included, can upset your dog's digestive system and cause her diarrhea and, in some cases, vomiting.
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.
