From our point of view, dogs can be both weird and mind-blowing. Many of the things they do can be confusing, such as chasing their tails or sniffing butts. If you’ve had a dog, you know what we mean. In some cases, dogs will even eat grass. But why do dogs eat grass?

Essentially, dogs eat grass for a number of reasons, from digestion to plain boredom. If you’re worried about your dog’s health, don’t. Most of the time, grass is safe for dogs. However, there will be some safety concerns. 

With that, we’re here to tell you all about why dogs eat grass, as well as explanations about safety, management, and related concerns. 

Why Do Dogs Eat Grass?

Dogs don’t exactly tell us why they snack on the lawn, but vets have a few solid theories. The truth is, there are several reasons that can be considered. 

It’s Instinctual

Eating grass can be linked to a dog's behavioral instincts. Because their diet consists of animal and plant-based options, they instinctively eat grass as well. In essence, dogs eat grass because of their instincts. 

Grass Adds Fiber

Some dogs eat grass because of the fiber. Fiber helps dogs with digestion and bowel movements. Grass is sometimes an option for dogs that feel like they need more fiber. 

Soothes an Upset Stomach

One of the most popular theories is that dogs eat grass when they feel nauseous. While studies show that it’s mostly not the case, eating grass can help the stomach. It often works by either adding fiber or by helping expel something inside the stomach through vomiting. 

Boredom and Stress

Dogs may also eat grass as a way to pass the time or cope with anxiety. Just like people might snack when they’re restless, a dog might turn to grazing when they lack enough exercise, play, or mental stimulation.

Dogs Like the Taste

Believe it or not, some dogs just enjoy the taste or texture of grass. To them, it’s not that different from chewing on a toy, stick, or anything else interesting. Fresh, spring grass is especially tempting. 

Curiosity 

Some dogs eat grass mainly because they're curious about it. Usually, this includes puppies, as it might be their first time seeing and touching grass. Over time, this way of exploring can become a habit. 

Is It Ok for Dogs to Eat Grass?

The short answer is yes. It's okay for dogs to eat grass, and it's often safe for them. However, there are some things you should take note of. 

Chemicals and Pesticides

The biggest risk isn’t the grass itself, but the chemicals that might reside on it. Lawns that are regularly treated and maintained might have harmful pesticides, herbicides, or fertilizers. So if you keep your lawn treated, then be sure to keep your dog away from it. 

Sharp or Poisonous Plants

Grass can also have sharp seeds, foxtails, and other objects. These can easily get stuck in your dog's mouth, throat, or gastrointestinal system. This can result in coughing, pain, irritation, and infection. The grass itself can also come with poisonous plants.

Parasites and Bacteria

Grass can also be a carrier for parasites like roundworms or hookworms if contaminated by the fecal matter of other animals. While the risk isn’t extremely high, it’s another reason to make sure your dog is up to date on parasite prevention.

Why Do Dogs Eat Grass to Vomit? 

Generally, dogs don’t eat grass to vomit. This popular reason is largely a myth. Many studies suggest that only a very small percentage of dogs who eat grass vomit.

Grass is fibrous and hard to digest. The long and sharp blades can also tickle the intestinal lining of dogs, which may result in vomiting. In this sense, it’s more of a side effect rather than an intentional action.
