It is not unusual to see a dog acting like a little cow, standing in the grass and eating it. But why do dogs do that? Are they sick? Are they bored? Is it just a natural instinct? There can be several different reasons why a dog might eat grass, and if we are not familiar with it, we might get confused and frustrated.

It would be a good idea to check out whether this behavior is something we should worry about or is it just natural behavior we can expect from our dogs. So let’s check it out.

An eating disorder called pica

Maybe the reason your dog is eating grass is a condition called „pica. “ Pica is a disease that compels the eating of non-food objects such as dirt, toys, and grass. Both humans and animals can suffer from pica.

Sign of illness or stomach problems?

Many dog owners believe that grass eating is a sign of illness, and sometimes that's true. Dogs can eat grass to induce vomit; it is believed that long, unchewed pieces of grass tickle dogs' throats and stimulate vomiting. They want to make themselves throw up because their stomach is irritated.

Some researchers have shown that most dogs that eat grass slowly rarely vomit afterward, but dogs that eat grass more rapidly almost always vomit. This finding raised the question of whether dogs that eat grass rapidly are doing so to relieve stomach discomfort after eating something that makes their stomach hurt. According to this theory, dogs don't eat grass in normal circumstances, but only when they need stomach relief.

Improved digestion

Other people believe that dogs eat grass to improve their digestion, treat intestinal worms, or fulfill some unmet nutritional need. Dogs' bodies have certain dietary needs, and when those needs have not been fulfilled, some functions are not going to perform normally.

Grass provides fibers that sometimes are missing from a dog’s diet, and in these cases, dogs eat grass to supplement those fibers, making it easier for them to pass gas and stool. That said, grass may actually help their bodily functions run more smoothly. Consult with your veterinarian, and if this is the most probable reason your dog is eating grass, make some diet changes - add more vegetables to your dogs' diet and increase fiber content.

Natural instincts

A lot of people believe that dogs eat grass because it is their natural instinct. Before dogs became so domesticated, they fed naturally on anything that they could find, and primitive dogs were natural omnivores, which means they were meat and plant-eaters. Modern dogs' ancestors used to eat their prey entirely, including the stomach content of plant-eating animals. Therefore, domesticated dogs instinctively include plant material in their diet.

Dogs and other canids in the wild consume anything that helps fulfill their basic dietary requirements. Examining stool samples shows that 11 - 47% of wolves eat grass.

Behavioral reasons

Another common assumption is that sometimes dogs can eat grass just to gain attention or out of boredom. If the owner is not providing the dog with enough interaction, the dog may try to interact with the owner by engaging in unusual or even forbidden behaviors.

Many people believe that dogs eat grass simply because it tastes good to them and they enjoy it.
