Why Do Dogs Eat Grass?

Are you worried that your adorable pup is always nibbling grass on your lawn? You aren’t alone. Grass eating is a common behaviour in dogs. In fact, surveys indicate that grass is the most commonly consumed plant by dogs. So, why does your pup seem to like eating grass so much? Let’s find out.

The behavior in animals and humans of eating things other than food is known as pica. There isn’t a single documented cause of pica, but in some cases, it may indicate that your dog has a nutritional deficiency. However, some dogs may eat non-food items because they are bored while others just like the taste. Most pet owners assume that dogs eat grass to induce vomit when they have an upset stomach. This is because some dogs quickly vomit immediately after eating grass. 

However, experts seem to refute this claim, noting that dogs aren’t smart enough to induce vomit as a solution to an upset stomach.  Besides, not all dogs that eat grass vomit afterward. A study done by researchers from the school of veterinary medicine at the University of California indicated that only 10% of dogs who ate grass had stomach problems before eating grass. About 90% of the other dogs surveyed didn’t have any stomach issues. This is evidence that dogs don’t eat grass to induce vomit.

Many vets agree that grass-eating is a normal behaviour in dogs. A close look at the anatomy of a dog shows that they are omnivorous. This means they derive their nutrition from both animal and plant food sources. They are also scavengers and will consume anything that helps meet their dietary needs. Thus, next time you see your pup eating grass, maybe they’re just following their natural instinct to scavenge. 

Furthermore, dogs need fibre in their diet if digestion is to occur smoothly. If your dog’s diet is low on roughage, they may be inclined to munch on grass as it’s a good source of fibre. 

Researchers did a study on a poodle dog who had a long term grass-eating behavior. They substituted the dog’s non-fiber diet with a high-fiber one. The poodle’s owner observed that the dog stopped the grass eating behavior after feeding on the high-fiber diet.

Dogs also eat grass due to psychological reasons. It’s just like people who bite their nails when bored or anxious. Dogs that suffer from separation anxiety may opt to eat grass to draw their owner’s attention or just to kill time. 

A simple explanation as to why your pup may like ingesting grass so much is maybe because they like it. They may enjoy the way the grass feels on their mouth. It isn’t uncommon to find dogs happily munching on the grass immediately when it emerges in spring.

Is Eating Grass Harmful?

Although grass may not add any nutritional value to your dog, the pet experts at We’re All About Pets told us it isn’t harmful. However, they stated that there is the danger that your dog may ingest toxic pesticides and herbicides sprayed on the grass. Dogs can also ingest worms and other intestinal parasites if they ingest grass that is contaminated with fecal matter. 

Dogs that like to munch on grass may also like to sample other plants and dirt. Always be on the lookout for any poisonous plants on your lawn as some, when ingested by your dog or cat, may be fatal. You should also give your dog their recommended dose of dewormers to keep them healthy.

Don’t confuse your pup’s grass munching with digging. Your dog will use their nose if they are digging and will often do this in your back garden.

How Can You Stop Your Dog From Eating Grass?

If there is a danger that your pup may ingest grass that’s contaminated with harmful herbicides, or fertilisers, you should encourage them to stop. If your dog responds to treats, discourage them from eating the grass in exchange for treats. You can also distract your pup every time they try to nibble grass with a verbal command. 

Supplementing your pup’s diet with high fibre food can also discourage this behaviour if they’re doing it due to nutritional deficiency. Dogs that eat grass due to boredom should be well-exercised and given enough time to interact with humans. Ensure you walk your dog and spend enough time with him. You can also buy them a play toy to keep them busy. When leaving your dog alone, leave them behind an old cloth that has your scent as this can be a good source of comfort.

Conclusion

In conclusion, grass eating is a common behavior in dogs. It’s more common in puppies as they love to explore everything with their mouth. However, they often outgrow this behaviour, especially if training is offered. If you’re worried that your pet is eating grass excessively, you should take them to the vet. If your dog is showing any unusual signs after eating grass, visit the vet as soon as possible as they may have ingested something toxic.
