Other people think that dogs eat grass when they are looking for nutrients. However, studies have shown that this is not the case.

Please read on and discover the common reasons for this behavior.

They Need To Be Sick:

There isn’t a definite answer yet as to why dogs eat grass and experts are still researching the issue, However, it seems that some people think that if their dog feels uneasy, they’ll eat grass in order to clear up their stomachs.

It might be a natural reaction and a kind of instinctive behavior from them.

Diet is Lacking:

Dogs may eat grass because they don’t get enough nutrients or minerals in their food. The plants in the ground might be filling the void left by the lack of nutrition in their diet.

One theory on why dogs eat grass is to do with their evolutionary path. Dogs used to eat “the whole animal” but can’t anymore. On average these were typically high in plant material which can turn them into herbivores too.


If your dog is the only one that’s getting any attention and they’re not getting enough mental or physical stimulation, then their tendency to eat grass might just be because of boredom. Chews are good for helping fight boredom between meal times plus a game of fetch with the ball.

Love The Taste:

Dogs may seem like natural scavengers, but they’re descended from wolves who were known for scavenging. The fact that they’re grazing in your garden is because it’s an area for them to do some foraging.


Research has suggested that some dogs may eat grass in order to help flush out any parasites in their intestine. The undigested grass could help the gut by enveloping the parasite with it and carrying it out as it does during digestion.





Dogs love a good meal of fresh grass, but it’s important to keep them safe in the process. It’s crucial to check for any fertilizers or herbicides that could be harmful to your pet. Your vet can also provide treatments for protection from lungworm, which your pet will get from snacking on lawns containing fertilizers and herbicides.
