Why Do Dogs Eat Grass?



Many dog owners wonder why their dog is eating grass. Eating grass in and of itself is not a sign of anything, as many dogs like the taste and enjoy a little vegetation to munch on. While it is common for dogs to eat grass, the reasons for dogs eating grass can differ between healthy and sick dogs. After years of working alongside veterinarians at VCA hospitals, Pet Nutritionist Susan Davis has valuable insight on when grass eating is harmless, and when to be concerned. Based on years of research, she has developed a holistic treatment plan for helping dogs who are eating grass due to an underlying condition.

Reasons Why Your Dog May Be Eating Grass
  • Some dogs just like the taste of grass.
  • Eating grass may be a way to fulfill an unmet nutritional need, such as fiber, vitamins or minerals.
  • Eating grass may be a dog's attempt to induce vomit or calm an upset stomach.
Signs Your Dog is Eating Grass Because of an Underlying Condition

To better understand why your dog is eating grass, ask yourself the following questions:

  1. Is your dog "drawn" to the grass, or showing signs of needing to get to the grass such as whining or pulling toward it?
  2. Does your dog eat grass and then vomit afterward? Is your dog vomiting frequently, or is your dog vomiting grass and bile?
  3. Is your dog eating large amounts of grass? Is your dog routinely wanting to eat grass?

Some grazing on grass is natural for a dog, but when they are eating grass frantically this can be a sign of acid stomach or digestive problems. Many times dogs eat grass as a way to make themselves vomit too. If you notice your dog eating grass frequently or eating a lot of grass, then it's important to watch for other signs of digestive problems. Many pet owners don't realize that their pets may be in pain from acid stomach.

Restoring the gut flora that leads to a healthy digestive tract is key to relieving your pet’s painful symptoms. Using gentle yet effective all natural supplements can help your dog and eventually stop them from eating grass. We’ve broken down the signs of acid stomach and acid reflux in dogs and what you can do to provide relief for your pet.

“My 9 year old Welsh Springer Spaniel mix, Max, didn't have much of an appetite and would frequently vomit. He would often rush out to eat grass and then vomit afterwards. I was worried because he was thin and seemed so uncomfortable. I followed the Ask Ariel program and changed his diet while using supplements such as Gastro ULC and Power Probiotic. l really wasn't expecting much because I had made prior changes before that hadn’t worked. Within just a few days, Max improved. He no longer was interested in eating grass and his vomiting stopped. Max is now at a healthy weight and it is so nice to see him so happy to see his meals.”

Stomach Acid and Acid Reflux in Dogs


Acid reflux and acid stomach in dogs are painful conditions. Acid collects in the stomach and irritates the stomach lining and esophagus. Over time, the stomach acid can wear away tissue in the esophagus, causing open sores or ulcers, which can bleed and make swallowing difficult and painful.

Common symptoms of acid reflux in dogs may include the following:


  • Lack of appetite, especially in the morning
  • Vomiting of bile
  • Throwing up undigested food shortly after its consumed
  • Coughing (pets with collapsed trachea often have acid reflux)
  • Regurgitation noises, burping and gagging
  • Hunching over after eating
  • Gulping or loud gurgling noises
  • Licking or smacking of the lips
  • Panting a few hours after meals
  • Lick Fits (frantic licking of floors, walls, grass, dirt)
  • Restlessness or pacing after eating

What To Do When Your Dog Vomits Yellow Bile After Eating Grass
Some dogs eat grass and vomit yellow bile and foam. Bile is acidic and can irritate the stomach. It appears as a yellowish foamy substance. Bile is produced by the liver and is squirted into the intestines to help with digestion of fats and protein. Bile can end up in the stomach, causing irritation, especially if a pet has an empty stomach.

If your dog eats grass and then vomits yellow bile afterward regularly, please take your dog to the veterinarian for a diagnosis. Finding the root cause of why your dog is eating grass and vomiting yellow bile can bring your pet fast relief.

Try to look for the signs to understand the reasons behind your dog's grass eating. Vomiting grass and bile regularly, are clear signs that something else may be going on. If you notice your dog has rumbling tummy noises after eating grass or after eating meals, loose stool, gas, vomiting, diarrhea, bad breath or other signs of digestive discomfort, it is important to bring this to the attention of your veterinarian. Basic laboratory tests for your dog (e.g., blood panel and urine analysis) will provide valuable information, as acid stomach can be a symptom of a more serious health condition such as kidney or liver disease, seizure activity or inflammatory bowel disease (IBD) in your dog.

The Best Diet for a Dog That Eats Grass and Vomits

Take a moment to look at the diet you are feeding your dog. One reason dogs eat grass is because they are typically eating foods and treats that contain grains, food allergens and starchy carbohydrates that they are having trouble digesting. For example, small bites of cheese or peanut butter may not seem like much, but they are high in fat and are huge allergens that can cause digestive discomfort. Many of the best-selling premium brands contain allergens or starchy carbohydrates that can cause a variety of digestive problems and lead to a weakened immune system. Many dogs that are eating grass to throw up have heartburn and acid reflux. These dogs do well eating a hypoallergenic, high-moisture diet and consuming several small meals spaced throughout the day. Once your pet's stomach feels more comfortable, the symptoms should be greatly reduced.

A holistic approach with supplements and diet changes (FREE diet tips on the packing slip with your order) can give your pet much needed relief.
