Why Do Dogs Eat Grass? Understanding Your Pet’s Behaviour

As someone who has worked in the pet industry for years and frequently consults with veterinarians, I’ve come across countless pet parents puzzled by their dog’s behaviour—especially when their dog suddenly starts eating grass like crazy. While occasional grass-eating is common and typically harmless, a sudden increase can raise concerns. Let’s explore why dogs eat grass, when it could signal a problem, and what you can do to manage this behaviour.

Why Do Dogs Eat Grass?

Grass-eating, or "pica" (the consumption of non-food items), is a behaviour observed in many dogs. While there isn’t one definitive answer, here are a few popular theories:

  • Dietary Deficiencies

Some experts believe that dogs eat grass to compensate for a lack of nutrients in their diet, such as fibre. However, dogs on well-balanced, commercial diets should not be nutritionally deficient (VCA Hospitals).

  • Digestive Relief

It’s a common belief that dogs consume grass to induce vomiting and relieve gastrointestinal discomfort. Interestingly, less than 25% of dogs vomit after eating grass, making this theory less conclusive. If your dog eats grass and throws up, it might not be intentional but could indicate an upset stomach (The Kennel Club).

  • Boredom or Anxiety

Dogs may eat grass out of boredom or as a coping mechanism for anxiety. Similar to how humans chew their nails, grass-eating can become a repetitive, self-soothing behaviour for dogs.

  • Instinctual Behaviour

Some researchers suggest that grass-eating is a natural behaviour inherited from wild canines, who consumed plant material to aid digestion or eliminate parasites. Even if your dog is well-fed, this instinct might persist.

Is It Bad for Dogs to Eat Grass?

In most cases, grass-eating isn’t harmful. However, it can become problematic if:

  1. The grass has been treated with pesticides, herbicides, or fertilizers.
  2. Your dog consumes excessive amounts and experiences side effects like vomiting or diarrheal.
  3. Grass-eating is accompanied by symptoms such as lethargy, loss of appetite, or signs of pain, which could indicate an underlying health issue.

If your dog eats grass and throws up frequently, it’s worth consulting your veterinarian to rule out any serious concerns.

Why Is My Dog Eating Grass and Throwing Up?

If your dog ate grass and threw up, it could mean they’re trying to relieve an upset stomach. Vomiting occasionally after eating grass isn’t unusual, but persistent vomiting or other symptoms like diarrheal and lethargy could indicate conditions such as:

  • Gastrointestinal inflammation
  • Parasites
  • Pancreatitis
  • Inflammatory bowel disease (IBD)

A veterinarian can perform tests to diagnose the issue and recommend appropriate treatment.

Preventive Measures and Management

To manage and reduce grass-eating behaviour in your dog, consider these steps:

  1. Schedule Regular Vet Visits: Routine check-ups can help identify and address any underlying health issues early, ensuring your dog stays healthy and happy.
  2. Evaluate Their Diet: Ensure your dog’s diet is well-balanced and meets their nutritional needs. If you’re unsure, consult with your veterinarian to assess whether dietary adjustments are necessary.
  3. Increase Physical Activity: Provide regular exercise to keep your dog physically and mentally stimulated. A tired dog is less likely to engage in undesirable behaviors like grass-eating.
  4. Offer Mental Stimulation: Interactive toys, puzzle feeders, and training sessions can help keep your dog’s mind active and reduce boredom-induced grass-eating.
  5. Create a Safe Environment: Ensure your dog’s outdoor areas are free from treated grass or toxic plants. Always supervise your dog when they’re outside to monitor their behavior.

When to Worry

While grass-eating is typically harmless, consult your vet if your dog displays any of these symptoms:

  • Frequent vomiting after eating grass
  • Persistent diarrhea
  • Lethargy or loss of energy
  • Loss of appetite
  • Signs of pain or discomfort

Your vet can perform tests to determine the cause and provide appropriate treatment to address the issue.

Conclusion

Grass-eating is a common behaviour in dogs, but a sudden increase or accompanying symptoms like vomiting or lethargy could signal a deeper issue. As someone who has spent years in the pet industry and frequently worked alongside veterinarians, I always recommend staying observant and proactive. If your dog is eating grass excessively, consult your vet to ensure their well-being.
Understanding why dogs eat grass can help you better support your furry friend. By providing a balanced diet, regular exercise, and plenty of mental stimulation, you can minimize this behaviour and keep your dog happy and healthy. Remember, every dog is unique, so it’s essential to tailor your approach to their specific needs.
