Dogs can have some curious habits, and eating grass is one that often puzzles pet owners. You might be at the park, on a nature hike, or watching your dog explore the backyard when suddenly, they pause, head down in a patch of long grass, and start munching on it. While some dogs will eat and digest it without issue, others might vomit it up—sometimes on your freshly cleaned floor! So, why do they do it, and is it a sign of something wrong? Let’s dig into some theories.
Plant Material In A Dog’s Diet
Most important of all, dogs are omnivorous. Although essentially carnivorous, recent evidence indicates that they do well on a mixture of plants and animal tissues. Fiber obtained from the plant material, such as bran and grains, is just as important for the function of their digestion. It helps in the regulation of blood sugar and aids in the maintenance of the balance of organisms in the gut. Fiber promotes proper function of the colon.
There are sources that lay claims on dogs eating grass primarily because of a lack of fiber, but most dogs that eat grass have what is referred to as a balanced diet. Therefore, fiber deficiency may not be the cause. Also, it is known that a small number of dogs develop pica, which is the drive to swallow or consume non-food items and it could explain grass eating, even though the evidence remains unclear.
Roots and Ancient Instincts
Dogs’ wild ancestors were hunters and scavengers who ate whatever they found. They consumed whole animals, including stomach contents, often filled with grasses. While today’s dogs get all their nutrients from pet foods, grass eating might be an instinct inherited from their wild roots. Wild dogs have been observed nibbling on grass too, which hints that this behavior is a natural part of dog life—even if we’re still left wondering about the specific reasons.
Possible Reasons for Eating Grass
Despite being natural, grass-eating remains mysterious. Here are some theories that could explain this behavior:
Intestinal Parasites
Some experts suggest that wild dogs eat grass to eliminate parasites in their intestines. However, since domestic dogs rarely need to worry about parasites due to regular vet care, this explanation is more relevant to wild animals.
Boredom
Many veterinarians and animal behaviorists agree that boredom can lead to grass-eating. Dogs might chew on grass for entertainment, especially if they lack mental and physical stimulation. Giving your dog a new toy or engaging them in play can often curb this habit. High-energy breeds, in particular, may need more activities to stay occupied.
Anxiety
Just as people may bite their nails when anxious, some dogs chew on grass to ease their nerves. Life changes like moving, a family member leaving, or even minor shifts in routine can trigger this reaction. Offering reassurance and maintaining a stable routine can help soothe an anxious dog.
Attention-Seeking
Some dogs may eat grass to get your attention, especially if they notice that it prompts a reaction from you. Dogs that crave interaction will find ways to be the center of attention, so be mindful of whether your response to this behavior reinforces it.
Immaturity
Younger dogs are more likely to explore the world by chewing on anything, including grass. Puppies are naturally curious and experiment with their environment, so this behavior is often seen in younger dogs.
Enjoying the Texture
Sometimes, it’s as simple as taste and texture. Grass could just be enjoyable for some dogs. Studies show only a small percentage of dogs vomit after eating grass, so for many, it’s a harmless activity.
Can Eating Grass Be Harmful to Dogs?
Eating grass, in small amounts and on occasion is not dangerous as a rule. But if your dog is constantly eating grass, it may be a symptom of something more serious. Grass is the only worry because of pesticides and herbicides, which can be toxic. You control what is sprayed on that beautiful lawn of yours. If you do use pest control products, choosing non-toxic alternatives can help keep your pets safe.
The threat increases the farther from your real estate If you have walked near treated fields or areas where pest control is used, your dogs may become exposed to harmful chemicals. Public parks as or in other communal lands can require herbicide use, both for restoration of native vegetation and aesthetics. Some areas may also restrict the types used due to health concerns.
Remember to watch what your dog chews on when you are out. The pesticide content in a few blades of grass is likely not to do any lasting harm, but it can make them temporarily ill. It is always a good idea to talk with your veterinarian if you have an inkling that something might be wrong after a walk.
Conclusion
In the grand scheme of things, grass-eating is usually a harmless quirk. If your pet is feeling alright otherwise and not vomiting profusely, you can probably allow him/her to crunch on their occasional greenery.
