You're enjoying a sunny afternoon when you spot your pup going to town on a patch of fresh grass. It's an all-too-familiar sight for many dog families, and you may be wondering why they do it. If you've ever caught your pup grazing on the lawn and wondered, "Why does my dog eat grass?", you're not alone. This behavior can puzzle even the most experienced dog families.
While it might seem odd (or even concerning), eating grass is actually quite common among dogs. Our SafetyPUP Luna is quite the grass connoisseur herself. But what does it mean? Is it safe? Should you try to stop it? In this Ultimate Guide to Why Dogs Eat Grass, we’ll break down the possible reasons behind this behavior, when to be concerned, and what you can do about it.
Why Do Dogs Eat Grass? 6 Common Reasons
While there’s no single answer to this question, experts and studies suggest several possible explanations:
1. Your PUP's DNA Contains Grassroots Behavior
Dogs are descendants of wild canines, like wolves and coyotes, who consume plants (including grass) as part of their natural diet. This behavior is believed to assist in purging intestinal parasites as the fibrous greens increase digestion speed and help eliminate worms. In the wild, dogs eat entire prey—including the stomach contents of herbivores—so they may have developed a taste for greens.
2. Ruff-age Intake - The Doggy Diet Hack
If your dog’s diet is running low on fiber, they might turn to nature’s salad bar—your lawn! Some veterinarians suggest that dogs may crave plant material when they’re lacking certain nutrients. A 2008 study published in the Journal of Veterinary Medical Science found that a poodle with a fiber-deficient diet stopped eating grass after switching to a high-fiber food.
3. Dogs Prefer Green Cure to the Pink Stuff
Are tummy troubles making your PUP reach for the green cure? One of the most common myths is that dogs eat grass to make themselves vomit. While some dogs do throw up after eating grass, studies show that only about 22% of dogs vomit after consuming it, and most don’t show signs of illness beforehand. This suggests that, while some dogs may eat grass when they feel nauseous, it’s not always an intentional remedy.
4. Mowing the Lawn to Pass the Time
Just like some dogs chew on shoes or dig holes when they’re bored, eating grass can be a way to pass the time. If your pup seems to graze when left alone or during quiet moments, they might need more stimulation through toys, playtime, or mental challenges.
5. A Taste for Turf
Some dogs just love grass! The texture, the smell, the freshness—it’s a sensory experience for them. Young, tender grass in spring can be slightly sweet, making it more appealing. If your dog is a grass connoisseur, they might simply be enjoying a light, leafy snack.
6. Keep Calm & Graze On
Eating grass could be your PUPs stress coping mechanism. Just like people bite their nails or tap their fingers, some dogs eat grass as a way to self-soothe. If your dog munches on grass after a stressful car ride or when there has been a lot of commotion at home, it might be a coping mechanism rather than a dietary need.
Is It Safe for Dogs to Eat Grass?
Most of the time, grass-eating is completely harmless, but persistent or excessive grazing could indicate an underlying issue that requires attention.
Lawns On Hulk Mode
Many lawns and parks are treated with pesticides, herbicides, or fertilizers that can be toxic if ingested. If your dog likes to graze, make sure they’re not eating from treated areas. While it would be cool, it is highly unlikely that your PUP will mutate into a world saving, evil banishing super hero. Although, they kind of naturally banish evil and save the world one human at a time.
Grass Buffet Comes with Free Germs
Public grass areas may be contaminated with feces from other animals, which can carry parasites like hookworms or roundworms. PUPs who have a balanced diet with probiotics and doggies well groomed with good hygiene in clean environments may be more protected. Be especially aware with puppies, senior dogs, or recently rescued dogs. Always supervise your dog and prevent them from grazing in high-traffic areas.
Digestive Blockages
Dogs can’t digest large amounts of grass easily, so excessive consumption may lead to digestive upset or, in rare cases, intestinal blockages. If your dog constantly eats grass and seems uncomfortable afterward, consult a veterinarian.
How to Stop Your Dog From Eating Grass
While grass-eating is usually normal, there are ways to curb the behavior if it’s excessive or unwanted:
-
Ensure a Balanced Diet: Talk to your vet about your dog’s food. If they’re lacking fiber or key nutrients, switching to a high-fiber diet might help reduce cravings.
-
Provide Mental & Physical Stimulation: More walks, playtime, and interactive toys can help prevent boredom and curb the urge to graze.
-
Train a Reliable “Leave It” Command: Teaching your dog to respond to “leave it” can prevent them from munching on grass during walks.
-
Offer Safe Alternatives: If your dog enjoys chewing plants, try providing dog-friendly veggies like carrot sticks, green beans, or lettuce as a safe alternative.
-
Monitor for Underlying Issues: If your dog obsessively eats grass, vomits frequently, or displays signs of illness, consult your veterinarian.
FAQ: Your Grass-Eating Questions Answered
Why is my dog eating grass all of a sudden?
If your dog suddenly starts eating grass more than usual, it could be due to dietary changes, boredom, stress, or mild digestive discomfort. If the behavior is excessive, check their diet and routine for changes.
Should I let my dog eat grass?
In most cases, yes! As long as the grass is free from pesticides and chemicals, occasional grazing is perfectly fine. However, if your dog eats large amounts or seems obsessive, it’s best to discourage it.
My dog is eating grass and throwing up—what should I do?
If your dog eats grass and vomits occasionally, it’s usually not a concern. However, frequent vomiting or signs of distress (like lethargy or diarrhea) could indicate an underlying issue. If this happens, consult a vet.
How do I stop my dog from eating grass on walks?
Try using a “leave it” command, keeping your dog engaged with treats or toys, and walking in areas with less grass. If they persist, check for possible dietary deficiencies.
Final Thoughts: Should You Worry About Grass-Eating?
For most dogs, eating grass is just another quirky habit—like rolling in the mud or chasing their tails. As long as they’re happy, healthy, and eating a balanced diet, the occasional grass snack is nothing to stress over. But if you’re ever in doubt, a quick chat with your vet can provide peace of mind.
