It is perfectly normal behavior for dogs to eat grass, according to a study carried out by researchers from the University of California. The behavior has even been observed among wild dogs.
In the above study, the researchers asked 47 owners of healthy dogs who had daily access to plants whether their dogs routinely ate plants. Close to 80% of the participants reported that their canine companions regularly ate grass or other plants.
The researchers then carried out another survey over the internet, asking dog owners with dogs that routinely ate plants to provide information about the kind of plants their dogs ate, as well as the frequency with which they ate plants.
The results of the survey showed that 79% of the dogs ate grass. Reports by the participants also showed that 68% of the dogs ate grass or other plants at least once a week. The findings of these two studies show that it is totally normal for your dog to eat grass all the time.
That said, it’s also good to note that dogs will sometimes eat grass when they are unwell. If your dog suddenly starts eating grass, observe them more keenly.
If you notice any signs of discomfort, or any symptoms like diarrhea, vomiting, loss of appetite, weight loss, lethargy, or bloody stool, quickly have your canine buddy checked out by a vet. Some illnesses that could cause your dog to eat grass include pancreatitis, inflammatory bowel disease, and gastric reflux.
