Why does my dog eat grass?

Many dogs love to smell, dig in, and eat grass. But should you be concerned if your dog is regularly dining on your lawn? Here, our Tucson vets discuss why dogs may habitually eat grass, and whether it is safe to do, in this post. 

Why do dogs eat grass?

Whether your dog eats grass on occasion or every time you leave the house, many dog owners are familiar with this behavior. But why does a dog eat grass? Some dogs will eat grass, vomit it up, and then continue to eat grass.

Should you be worried that your dog might have gastrointestinal issues? Perhaps you're wondering if they've consumed a poisonous substance, or if this is a sign that they have an underlying health condition that requires diagnosis. 

While a dog may vomit after they eat grass, this is relatively uncommon. Most dogs eat grass without showing any signs or symptoms of tummy issues. So, it seems unlikely that dogs eat grass to induce vomiting. Then why do they do it?

Physical Reasons A Dog Eats Grass 

Type 'why my dog eats grass' into your favorite search engine and you'll likely find that you are among many pet parents who deal with this issue. Reasons for this habit may vary. A nutritional deficiency may be one of the simplest explanations for why a dog eats grass. A dog that eats grass might be attempting to add more fiber to their diet to help them digest their food. 

After all, since dogs are omnivores, they need to dine on high-quality plants and meat to maintain their health. Eating grass may be an easy way for your dog to add roughage to their diet, helping to keep things moving through their digestive tract. 

Your dog may also be eating grass due to a gastrointestinal issue. Dogs can develop a variety of stomach and gastrointestinal issues, including gastroenteritis and pancreatitis. If your dog is eating grass and exhibiting other symptoms such as constipation, decreased energy, loss of appetite, or diarrhea, it's time to take him to the veterinarian for a checkup.

Psychological Reasons A Dog Eats Grass 

Just as people can have feelings of anxiety or boredom, so can dogs. If your dog doesn't exhibit any signs of digestive issues but devours grass, psychological reasons may be the culprit. 

For example, your dog may simply be suffering from boredom. If this is the case, increasing the intensity or distance of their walks may help to cut back on their grass eating habit. 

Separation anxiety may also be the reason your dog is eating grass. When you leave the house, consider leaving an old blanket or t-shirt with your scent on it for your dog. The familiar scent may reassure your dog, reducing their desire to eat 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 pooch reduce obsessive behaviors.
