One minute, your dog’s happily chasing butterflies in the backyard, and the next—there they are, munching away on your perfectly trimmed lawn like a miniature cow. Sound familiar? If you’ve caught your pup indulging in this unexpected salad bar more than once, you’re definitely not alone. But is this behavior normal, or should you be worried? Let’s dig into the grassy truth!

Is It Normal for Dogs to Eat Grass?

Yes, it’s surprisingly normal! Studies show that nearly 80% of dogs nibble on grass occasionally, and for most, it’s perfectly harmless. But why do they do it? Let’s explore!


The Curious Case of Grass-Eating Dogs

“Dogs eat grass for many reasons, and most of them have nothing to do with health issues,” explains Dr. Jane Barker, a canine behaviorist at the Canine Wellness Institute. “It’s often just part of their natural instincts or curiosity.”

Here are the most common reasons why your dog might turn your lawn into their personal buffet:

Pro Tip: If you notice your pup consistently heads for the same patch of grass, it might be about the specific taste or scent of that area!


Is It a Sign of an Upset Stomach?

One of the most popular myths is that dogs eat grass to make themselves vomit. While it’s true that some dogs vomit after eating grass, research suggests that only about 25% of dogs vomit after grazing, and most show no signs of stomach distress beforehand.

“Occasional grass-eating isn’t usually linked to nausea,” says Dr. Barker. “However, if you notice your dog heading straight for the grass after a meal and vomiting frequently, it’s worth consulting your vet.”

Friendly Tip: If it’s just an occasional nibble, relax! But if you’re starting to wonder if your pup thinks he’s a sheep, read on…
