Did You know one of the most asked dog related questions out there is “Why do dogs eat grass?” Well, I think it’s safe to say most if not all dog owners have witnessed their pooch eating grass at one time or another only to see them heave it back up.
I have one dog in particular who is a grass eater and we never know whether to really be concerned. I have gathered some explanations from around the web and compiled them, but remember I am not a medical professional.
“Evidence suggests that most dogs that eat grass aren’t unwell beforehand, or at least they don’t seem so. In fact, fewer than 10% of dogs seem to be sick before eating grass, according to their owners. And grass-eating doesn’t usually lead to throwing up, as less than 25% of dogs that eat grass vomit regularly after grazing.”

“Dogs do not have the means to digest grass, as they lack the enzymes needed to break down the fibres. Thus, there is little nutritional value in it for them. One reason for eating grass may be due to a feeling of nausea. It is possible that dogs learn this is a temporary solution for stomach irritation”. – See more at: https://moderndogmagazine.com/articles/vet-s-take-why-dogs-eat-grass/297#sthash.5dVEg019.dpuf
“The most common explanation for grass-eating is that it helps
dogs purge their systems. Like humans, dogs can suffer from gastrointestinal issues including upset stomach, nausea, bloating and illness from pathogenic microbes.”

Veterinarians speculate that dogs eat grass for a variety of reasons, from attempting to quell nausea to reducing bloating. While dogs are unable to digest grass, the practice is largely harmless. It is relatively common for dogs to eat grass.

It seems that everywhere I look the answer is basically the same, it is a normal act that helps your dog when they have an upset tummy. However if your dog is doing this more than a couple times a week, it may be a good idea to discuss this with your vet. You always want to play it safe as there may be an underlying problem.
