Dogs Eating Grass: Why Do They Do It?

Dogs Eating Grass: Why Do They Do It?

Many dog owners wonder why their companions seem to enjoy eating grass. Today, our Hohenwald vets discuss some reasons why your dog may be eating grass and the effects it will have.

Why Dogs Eat Grass

Pet owners are frequently left scratching their heads, unsure why their dogs seem to enjoy eating grass. Many dogs will eat grass, vomit, and then return to eating grass.

Could this be an indication that something in the dog's stomach needs to be brought to the surface? Is there anything poisonous in the dog's stomach? Is the dog self-treating a medical condition that has yet to be diagnosed?

Some dogs do vomit after eating grass, but this isn't true for all of them. The vast majority of dogs eat grass with no signs or symptoms of stomach upset. As a result, it appears that dogs do not eat grass to induce vomiting. Why do they do it, then?

Physical Reasons Why Dogs Eat Grass

Dogs, like people, require fiber to maintain a healthy digestive system. Dogs, after all, are omnivores. This means that plant foods, as well as high-quality meat, are essential for good health. The grass is a simple way for your dog to get more roughage in their diet, which can help keep things moving through their digestive tract.

However, if your dog is eating grass but also displaying symptoms of stomach upset, there could be a medical issue. Dogs can develop a variety of stomach and gastrointestinal problems, including pancreatitis and inflammatory bowel disease. If your dog is eating grass and has other symptoms like a lack of appetite, low energy, diarrhea, or constipation, you should take them to the vet for an examination.

Psychological Reasons Why Dogs Eat Grass

Dogs will frequently eat grass out of boredom or anxiety, similar to how people bite their nails. Consider psychological reasons for your dog's behavior if they aren't showing any signs of digestive problems but are constantly munching on grass.

If your dog is simply bored, increasing the length, distance, or intensity of his walks could help him stop eating grass.

Separation anxiety may also be the cause of your dog's grass-eating. When you leave the house, leave an old blanket or t-shirt with your scent on it with your dog. Your dog may find the familiar scent reassuring, which will help them stop eating grass.

Some dogs show obsessive behaviors. If your dog is obsessively eating grass, your vet will be able to advise you on how to help your pup reduce obsessive behaviors.

How Eating Grass Effects Dogs

If your dog is otherwise healthy and on regular parasite prevention medication, eating grass is considered to be a safe behavior.

To help keep your grass-nibbling pooch healthy, make sure that there are no herbicides, pesticides, or fertilizers on the grass your dog decides to snack on.
