dog. Love them as much as you want, but you can't stop them from rampaging all kinds of mud, slugs, stones, non-existent homework, and yes, poop. But have you ever wondered why do they eat anything? For example, why do dogs eat grass?

I'm glad you asked. This canine conundrum has some interesting answers. Well, at least in theory. Canine neuroscience is a growing field of research, but scientists have yet to uncover the exact motivation behind this mysterious behavior.

Dr Emily Blackwell, lecturer in companion animal behavior and welfare at the University of Bristol, explains: “The few studies that have investigated this question are inconclusive.'' “There are many possible reasons for dog herding, and there is more than one correct answer.”

That being said, what are the valid explanations for why dogs eat grass? Here's everything you need to know.

Why do dogs eat grass?

First, it is thought that eating grass can be a sign of anxiety or conflict in dogs, perhaps suppressing the urge to perform another behavior.

“It could be migratory behavior, which is what happens when animals have conflicting motivations,” Blackwell explains. “It's like when we're sitting in the dentist's waiting room. We might really want to escape, so we do something else, like bite our nails, to relieve our anxiety.”

However, for many dogs, eating grass can be a way to chase you for affection.

“If the owner responds to this behavior, the dog quickly learns that it's a good way to get attention,” Blackwell says.

“Admittedly, this is not one of the most common attention-seeking behaviors, but it can develop for that reason. And if they don't get a response from you, they'll look elsewhere.” They may just be grazing because they don't have much to do.”

But what if your dog is feasting on your front lawn when you're not around? Surely that's not howling for attention, right? In fact, it could be because your dog is trying to supplement his diet.

“Some people have theorized that dogs do this to get more fiber in their diets,” Blackwell says. “But this is just a theory; it has not been tested whether dogs with less fiber are more likely to eat grass.”

What about the most worrying possibility? Is your pup guzzling grass with an upset stomach?Again, potentially. After all, there's a theory that wolves also eat grass to get rid of parasites in their intestines.

But grass is unlikely cause Your dog gets sick. One 2008 study found that while 68% of dogs ate grass regularly; Only 22 percent of them subsequently become ill.. All in all, there's a pretty good chance you'll never have to remove dog vomit from your lawn.

And what if they were sick? Well, be thankful they didn't eat something even worse…

Why do dogs eat poop?

We are all friends here. It's okay to admit that you've seen your dog eat its own poop or the poop of other animals.

Fortunately, Blackwell says feces are unlikely to harm puppies unless they come from an animal with a serious illness.

But, unfortunately, just like with grass, we don't know exactly why dogs want to crawl into feces. However, dog behavior experts believe that doo-doo dining may be due to a dog's curiosity at a young age.

“Puppies are naturally exploratory and will taste everything,” Blackwell says. “Puppies don't find the taste or smell of feces as unpleasant as we do.”

But even if the taste isn't the selling point, you can inadvertently encourage your dog to eat feces when you're trying to prevent the behavior itself.

“Usually, this behavior results in the dog owner running up to the fecal area during a walk and trying to get there first to stop the dog. However, this is a signal that the fecal matter is important to the owner. “And that may make the dog more determined to get there before the owner.”

“So many dogs actually eat poop because it's mostly trained by their owners. It's all about how you react.”

Bottom line: If you spot an unsuspecting number two while walking in the park, the most important reaction is not to rush towards him. Especially if you don't have a dog (which will look really weird).
