Why dogs eating grass?

All dog owners can attest to having witnessed their dogs eat grass before. In fact, this is such a common occurrence in dogs that vets generally consider it a normal behaviour. But just what is the reason for this? Is it because, as the widespread myth suggests, they are sick? Or do they just dig the taste of grass? This is one question for which there is no conclusive answer.

The general theory is that a dog that eats grass is sick and needs to vomit. But studies have debunked this myth, showing that the majority of dogs who consume grass are well and do not vomit after doing so. Benjamin Hart, a vet who has studied animal behaviour for nearly 50 years says, “We believe it’s a trait they inherited from their wild ancestors. We know that wolves and cougars eat grass. That’s because they carry intestinal parasites. That’s just part and parcel of being in nature. Wild animals don’t have anything like the medicines we have for controlling worms. But by eating grass on a regular basis, they can prevent a buildup by purging their systems of these parasites.”

Unlike cats, dogs are not carnivores; they require vegetables in their diet to meet their nutritional needs. Experts speculate that a possible reason why dogs eat grass is to compensate for their dietary deficiency. It is reported that owners who incorporate vegetables like spinach, broccoli and carrots to their dog’s diet saw a reduction in their dog’s grazing.

While eating grass poses no serious problems, you should be careful to keep your dog away from lawns that have been chemically treated or that contain toxic plants. No one knows for sure why dogs find grass so appealing but since it is generally harmless, there is no need to panic whenever you catch Fido munching on some grass.
