Why dogs eat grass is a common question of many pet owners with no easy go-to answer. Eating grass is a fairly typical condition of dogs and cats. Many experts theorize it is a trait inherited from our pets’ wild ancestors. Dogs used to eat entire animals and would get plant sources from the stomachs of these rodents or other small animals. Wild dogs would also scavenge for berries, fruits, and other plant materials.
Eating grass is not associated with any known gastrointestinal sickness or underlying illness. Most experts agree that it is alright to let your dog eat grass as long as it is not causing any major problems. Always keep your pets away from any lawns that may have been chemically treated or have toxic plants that could cause your pet to become sick.
