Why do dogs eat grass?

July 15, 2017

I’m am going to try and answer the age-old question. Why do dogs eat grass?

The common answer is they eat grass because of intestinal disturbances. To prove that, researchers in Australia compared two sets of dogs. The test group had a food additive that caused loose stools. The researchers observed that the control group ate more grass.

These researchers also tested the theory that dogs eat grass to induce vomiting. They concluded that grass eating is a common behavior in apparently normal dogs that is unrelated to illness or vomiting.

Another theory is dogs eat grass because they’re fulfilling some unmet nutritional need. Researchers reported on a miniature poodle who ate grass and then vomited every day for seven years. Three days after putting the dog on a high-fiber diet, the dog stopped eating grass.

I treated a middle-aged dog who insisted on eating dirt and grass. In Eastern medicine, there is an imbalance called stomach heat. We cured this dog by switching his diet to cooling foods.

Some suggest that grass eating helped canine ancestors purge intestinal parasites by increasing bowel motility and by essentially lassoing the worms and flushing them out.

Some think dogs eat grass because they’re bored. If so, exercise and a stimulating environment may be the cure.

I don’t know maybe dogs eat grass because they like to.
