Dogs eat grass for several common reasons. They may simply like the taste or texture, especially since dogs are omnivores and sometimes enjoy plants. Some dogs eat grass because they are bored and seek mental stimulation. Others might eat grass to get more fiber in their diet, helping digestion and stool passage. Contrary to popular belief, dogs do not usually eat grass to intentionally make themselves sick, as only a small percentage vomit afterward. Occasionally, eating grass could be related to dietary deficiencies or a medical need like flushing out parasites, but in most cases, it is a normal behavior with multiple reasons including enjoyment, boredom, and fiber intake.
