A popularly held belief is that that when dogs have upset stomachs, they eat grass to induce vomiting and purge their stomachs of whatever is making their tummies feel upset. Turns out, that idea is closer to myth than it is truth.
Though it is true that wild canines will eat grass to help purge their digestive systems of harmful parasites, that is not necessarily the case with your pet dog at home. Researchers from University of California, Davis debunked this popular theory with a simple study.
UC Davis conducted a survey using 25 veterinary students who happened to be dog owners, and 47 regular dog owners who happened to bring their pet dogs to the UC Davis teaching hospital for outpatient medical care. The survey concluded that it’s very common to see dogs eating grass since 79% of those surveyed had observed their dogs doing just that. However, when questioned further bout how their dog felt, whether they showed signs of illness or if there vomiting after eating the grass, only 4 dogs showed signs of illness before or after eating the grass and only 6 of the dogs were seen vomiting after eating grass.
That means that about 8% of dog owners in the study said their dog seemed ill before eating grass and 22% claimed their dogs got sick and vomited after eating grass. That’s a small percentage of the dogs in the study and the findings seem to debunk the whole “dogs eating grass mainly to cure illness or upset stomach” theory.
So why does your dog like to eat grass?
Well, since dogs will eat just about anything they can get their paws or mouth on, they are more than likely just chewing on or eating the grass because they like it. It’s closer to the truth to say that grass is just one of the many things dogs simply enjoy nibbling on.
So that’s why your dog likes to eat grass.
