Grass Grazing and Dogs


“Chewing, chewing, chewing all day long.” For most of us, we associate this little chant with Violet Beauregarde, an iconic antagonist from Charlie and the Chocolate factory. Here, at Bullyfambam, we like to associate things with dogs, though. So, without further ado, the above chant might more accurately describe the life of our dogs. You might notice that your dog likes to chew– a lot. Many dogs especially like to chew on grass, and, if your dog is one who does, then you probably find yourself questioning it– a lot. In this post, we’ll discuss a couple theories about why dogs like grass so much.

There’s a lot of speculation with not a lot of research to back it up about why dogs eat grass. Even the few studies that have been conducted have left us with inconclusive answers. As a curious dog owner myself, I have heard a myriad of reasons why dogs might be eating grass.

One of the main contenders is that dogs who eat grass do not derive enough nutrients from their dog food. Thus, the dogs look elsewhere for these vitamins– your shoes, random household items, and the grass. However, this theory fails to recognize that many pet owners thoroughly investigate dog food brands. Most pet owners select food that will give their dogs all of the core nutrients that dogs need. Veterinarians even recommend specific dog food brands that ensure a well-balanced diet, geared towards your specific pet. With that being said, the above theory that dogs who eat grass lack vitamins doesn’t seem to make much sense.

People also believe that dogs eat grass when they have a stomach ache. But, there is not much proof that grass actually relieves stomach aches. In fact, it could be the opposite, and that eating grass causes the stomach aches. The truth is that the testing that has been done has yet to advance enough to determine which is the case. 

With that being said, grass is a good source of fiber and can aid in your dog’s digestion.

There are still more theories that postulate that dogs graze on grass as an ancestral instinct. Because dogs weren’t always domesticated, they did their own hunting and grazing, and many people believe that some of those inclinations continue to linger. So, perhaps when your dog eats grass, it is more of an innate impulse, than a behavioral issue. 

In reality, though, it could be as simple as your dog likes to eat grass. Sometimes we bite our finger nails. It’s not an inherently bad habit and it doesn’t necessarily add up to anything more than the act itself. 

The only concern is if chemical pesticides are used on your dog’s chomping grounds. If that’s the case, use treats to distract your pet from eating the grass. If you feel as though your pet has ingested pesticide or is over eating the grass contact your vet immediately. The former can lead to internal issues. The latter may be a sign of something else, ranging in severity from anxiety to pancreatitis.
