Why Do Dogs Eat Grass? And How To Prevent It Leave a comment

Some dog owners and veterinarians assume that why dogs eat grass is a form of pica, or eating strange items, sometimes caused by a diet deficiency. Many diet deficiencies are rooted in missing vitamins, nutrients, or minerals absent from daily intake. For example, it could be your dog’s way of getting more fiber, which helps them pass gas and stools and assist other bodily functions.

But if a dog’s diet is complete and balanced, then why do dogs eat grass? Dogs’ digestive systems, dietary needs, and cravings have evolved to fit domesticated dogs’ lifestyles. While canines in the wild weren’t getting their primary source of nutrients from grass, eating an entire animal provided an optimal diet, primarily if the animal’s diet consisted of various plants.

Is Eating Grass Bad For Dogs?

The consumption of grass can sign that your dog is attempting to relieve an upset stomach, and some pups do vomit soon after eating it. That said, fewer than 25 percent of dogs vomit from eating grass, and only 10 percent show signs of illness before eating grass, meaning most are not likely to eat it because they’re sick.

But while it’s not typically harmful to dogs, eating grass can cause intestinal parasites that are easily picked up from animal droppings and stools. It’s also important to note that the herbicides and pesticides sprayed on your lawn can be harmful to your pup. If you are worried about why dogs eat grass, you can visit a veterinary clinic to determine any underlying illness behind this behavior.

When Should You Take Action?

If you notice them eating grass more frequently or excessively, be alert of potential underlying illnesses, your dog attempts to self-treat. Also, look for vomiting, diarrhea, weight loss, decreased appetite, blood in the stool, lethargy, or lip licking.

Always monitor your dog when there are house plants nearby, as certain varieties can cause toxicity if they’re chewed or ingested. While chewing on the lawn is a standard behavioral action in many canines, you can train your dog out of the behavior to help provide peace of mind.

It’s always best to consult with your vet if you think your dog has chewed on a toxic house plant or possibly ingested too much grass or small amounts of chemicals. The vet will perform assessments like fecal samples, blood tests, or even physical exams to determine underlying conditions.

If your dog doesn’t exhibit any symptoms, but you feel that they may have ingested too much grass, keep them hydrated and allow time for potty breaks. Have your dog fast 8-12 hours before introducing food slowly. After 12 hours, if your dog continues to show signs, check in with your veterinarian.

Unless they’re doing it excessively, it can be useful for them! It adds a little fiber to their diet and helps with their digestion. Some dogs like it as a little springtime snack. However, if they overeat, they’ll vomit, which is another way they regulate their digestion by eating grass.

Dogs do this when they’re just a little sick or have eaten something off. Of course, if they are actively poisoned or too sick, they won’t need any help to vomit. Eating grass is just something dogs do, and it has the bonus of small digestive benefits.

Interestingly, eating cicadas is also suitable for a dog. It’s a nice boost in protein and an excellent little crunch. Still, anything in excess is wrong. Dogs are reasonably good about grass, though, and it’s hard to overeat grass when you have teeth that are not meant for chopping things.
