Understanding the reasons for eating grass by pet dogs

Dogs have always been relying on and have soft corners for meats and bones. As dog parents, you might have often noticed that your pet quite often goes outdoors or on the lawn and enjoys his time while eating grass. It is an intriguing scene as they are not herbivores, and neither is a usual item to eat. Let us discuss a few factors that shall guide you, clear your mind and help you identify the reasons behind this behavior.


Since dogs are natural omnivores and eat both meat and plants, eating grass comes instinctively to them. Any eatables that would soothe their taste buds and fill up their stomach, they would eat it. Previously, before domestication, they would rely on both plants and animals to fulfill their basic food requirements. This behavior has hereditarily transferred through generations and still prevails. It is one of the reasons because of which you might often notice that they are grazing in the grass and happily munches on it.

Inducing to vomit

It is a common observation that some pets after eating grass vomit out the meal eaten previously. Vomiting helps in relieving specific distress, which is just temporary. In cases when there is an issue of digestion and wants to throw up, they are often seen eating grass. Ingesting grass induces puke and gets rid of the undigested food. Although there is no proper evidence behind this, if eating grass helps them relax, there is nothing to worry about. However, once a while throwing up is okay, if this behavior continues for long and regularly, you must seek a doctor’s advice.

Nutritional deficiency

Often the urge to eat some other food, apart from regular meals, can indicate a nutritional deficiency. In the case of dogs, the need for more nutrients like vitamins, minerals, and roughage in their daily diet may urge them to eat grasses high on fiber. This condition in dogs is known as pica.

Gastrointestinal disease

Ingesting grass due to discomfort in digesting other food can also be a symptom of underlying issues like the gastrointestinal disease. In such cases, the digestive tract swells up and may also lead to blood loss in severe cases. Besides, there may be instances of diarrhea, weight loss, and laziness. To relieve themselves from it, pet dogs often eat grasses, which induce them to vomit.

Taste of grass

Apart from the health reasons, you may observe your pet inclined towards eating grass might be due to its taste. The preferable tastes and smell for particular objects in dogs are very different from their human counterparts. They generally like the smell of shoes, dirty laundry, and mud, which are among the dislikes in the case of humans. Similarly, some dogs eat grass only because of its taste.


There are certain breeds of self-reliable dogs and do not mind when left alone at home for a specified period. They manage to keep themselves busy and engaged in their activities. However, some do not like to stay alone. Loneliness often leads to unnatural behavior, which is mostly destructive. To calm themselves down and keep distracted from loneliness, nibbling on the grass is readily available on the lawn or outdoors. It helps them pass their time while waiting for their pet parents to return home and accompany them.

Parasites like roundworms and hookworms live in infected areas and lay eggs there. Grazing in the grass may result in infection with such worms in their digestive tract and their fur.
