Why Dog’s Eat Grass

Remember, occasional grass eating is generally normal for dogs. However, if it’s excessive or accompanied by signs of illness, it’s important to seek veterinary advice.

Additionally, ensure the grass your dog has access to is free from harmful pesticides or chemicals.

Natural Instinct

  • Dogs may eat grass due to an innate instinct. Their ancestors, wolves, often consumed plant matter as a part of their diet. Dogs may retain this natural inclination.

Nutritional Need

  • Dogs might eat grass to fulfill a nutritional need, especially if their diet is lacking in certain nutrients. Grass can provide fiber, which aids in digestion.

Digestive Aid

  • Grass can act as a digestive aid. It can help induce vomiting to relieve an upset stomach, although not all dogs that eat grass vomit.

Boredom or Anxiety

  • Boredom or anxiety can lead dogs to eat grass. This behavior might be more common in dogs that are left alone for long periods or lack sufficient physical or mental stimulation.


  • Some dogs simply enjoy the texture or taste of grass. They may nibble on grass during walks or outdoor play without any underlying health issue.

Attention-Seeking Behavior

  • Dogs may learn to eat grass as a way to get attention from their owners, especially if they notice that it prompts a reaction.

Gastrointestinal Issues

  • In some cases, eating grass may be a sign of gastrointestinal issues. If a dog is frequently eating grass and showing signs of discomfort, it’s important to consult a veterinarian.

What To Do If Your Dog Is Eating Grass

  1. Monitor the Behavior: Observe how often your dog eats grass and whether there are any accompanying symptoms like vomiting, diarrhea, or signs of discomfort.
  2. Veterinary Check-Up: If your dog eats grass frequently or seems unwell, consult your veterinarian to rule out any underlying health issues.
  3. Ensure a Balanced Diet: Make sure your dog is eating a balanced diet appropriate for their age, size, and activity level.

  5. Mental and Physical Stimulation: Increase exercise and provide more toys or activities to reduce boredom.
  6. Avoid Pesticides and Chemicals: Ensure the grass your dog has access to is free from harmful pesticides, herbicides, or fertilizers that can be toxic.

When to Worry

  • Accompanied by Symptoms: If grass eating is accompanied by vomiting, diarrhea, weight loss, or lack of appetite, see your veterinarian.
  • Eating Toxic Plants: Make sure your dog is not eating plants that are toxic to dogs. Familiarize yourself with common toxic plants and keep your dog away from them.

Should You Stop a Dog That’s Eating Grass?

  1. Chemically Treated Grass: If the grass has been treated with pesticides, fertilizers, or other chemicals, prevent your dog from eating it to avoid poisoning.
  2. Excessive Eating: If your dog is eating large amounts of grass and especially if they are vomiting frequently after eating grass, it’s a good idea to stop them and consult your veterinarian.

Why is My Dog Frantically Licking Grass in the Middle of the Night?

If your dog is frantically eating grass in the middle of the night, it could be due to several reasons. Understanding this behavior involves considering both physical and psychological factors:

1. Gastrointestinal Discomfort

  • Your dog might be experiencing stomach upset or discomfort. Dogs often eat grass to induce vomiting when they feel unwell, as grass can irritate the throat and stomach lining.

2. Dietary Needs or Deficiencies

  • The dog may be trying to supplement its diet, especially if it’s lacking in certain nutrients. While grass isn’t particularly nutritious, dogs might instinctively seek it out if they feel their diet is inadequate.

3. Anxiety or Stress

  • Anxiety, stress, or boredom can manifest in unusual behaviors like eating grass. If this happens predominantly at night, it might be a response to anxiety or stressors that are more prominent during these hours.

4. Habit or Behavioral Issues

  • The behavior could have become a habit or an attention-seeking behavior, especially if the dog has learned that eating grass gets a reaction from you.

5. Nausea or Illness

  • Nausea can be more pronounced at night, leading to an increase in grass eating. This can be due to various underlying health issues.

6. Changes in Environment or Routine

  • Changes in the dog’s environment or routine can cause stress or anxiety, leading to unusual behaviors. This can include changes in the household, schedule changes, or even changes in the outside environment.

What to Do

  • Monitor the Behavior: Observe if there are any other signs of distress or illness, such as vomiting, diarrhea, lethargy, or changes in appetite.
  • Evaluate the Diet: Ensure your dog’s diet is balanced and meets all nutritional needs.
  • Environmental Enrichment: Provide adequate mental and physical stimulation.
  • Reduce Stress: Identify and mitigate potential stressors in your dog’s environment.
