Observing your dog munching on grass can be a perplexing sight, leaving many pet parents to wonder: is this normal, a sign of illness, or just a quirky habit? While many dogs occasionally snack on grass, a dog that keeps eating grass, especially excessively or with accompanying symptoms, might be trying to tell you something. Understanding the common reasons behind this behavior and knowing what you should do if your dog keeps eating grass is crucial for ensuring their health and well-being.
Understanding Why Your Dog Eats Grass: Is It Normal?
Eating grass is a surprisingly common and natural behavior for dogs, observed in both domesticated pets and their wild counterparts. It’s often considered normal, but the underlying reasons can vary.
Common Reasons Dogs Eat Grass
There are several theories as to why your canine companion might be grazing. It’s not always a cause for alarm, but recognizing the potential motivations can help you determine the best course of action.
- They simply enjoy it: Despite their carnivorous reputation, dogs are omnivores and often enjoy the taste and texture of grass. The seasonality can even play a role, with some dogs showing a preference during specific times of the year, possibly due to changes in grass palatability.
- Boredom or anxiety: A dog that isn’t receiving enough mental stimulation or physical exercise might turn to behaviors like eating grass, digging, or excessive chewing. It can be a self-soothing mechanism or a way to pass the time. If your dog starts eating grass more frequently and shows other signs of restlessness, considering increased enrichment might be a good idea.
- Dietary fiber deficiency: Some research suggests dogs might eat grass to supplement their diet with fiber. A notable case study reported a dog that regularly ate grass and vomited for seven years, stopping the behavior when switched to a high-fiber diet. If you suspect your dog’s diet is lacking, consult your vet before making changes. For dogs that seem uninterested in their regular meals, finding out what to feed a dog not eating can be a related concern.
- Aid in expelling parasites: Another theory proposes that the undigested blades of grass can help dogs “clean out” their digestive tract. The fibrous material might wrap around intestinal parasites, aiding in their expulsion from the body.

The Normality of Grass Eating
Yes, for many dogs, eating grass is entirely normal. A survey involving 1,500 dog owners revealed that nearly 70% reported their dogs consuming plants daily or at least weekly, with younger dogs showing this behavior most frequently. As omnivores, dogs are naturally inclined to eat both meat and plant matter, making occasional grass consumption a part of their natural diet.
When to Be Concerned: Signs to Watch For
While occasional grass eating is generally benign, certain circumstances and accompanying symptoms warrant closer attention. Knowing when to worry and what should you do if your dog keeps eating grass excessively or gets sick is paramount.
Potential Dangers of Eating Grass
Even if the act itself is normal, the environment can pose risks:
- Treated grass: Never allow your dog to eat grass that has been treated with fertilizers, herbicides, or pesticides. These chemicals can be highly toxic and lead to serious health issues.
- Parasites: Slugs and snails that travel over grass can carry lungworm larvae. Ingesting these can infect your dog with lungworm, a serious parasitic disease. Regularly deworming your dog is crucial for prevention.
When to Contact Your Vet
If you notice any of the following, it’s time to consult your veterinarian:
- Excessive or obsessive grass eating: If your dog seems unusually preoccupied with eating grass, far more than an occasional nibble, it could signal an underlying issue.
- Eating grass and then vomiting frequently: While some dogs might eat grass to induce vomiting when they feel unwell, persistent vomiting after grass consumption (or any vomiting) needs veterinary attention.
- Appetite changes: If your dog is eating grass but not their regular food, or if they’re otherwise not eating what you typically give them, this is a significant red flag.
- Changes in energy levels or demeanor: If your dog appears unwell, lethargic, or significantly less active than usual.
- Gastrointestinal distress: Symptoms like diarrhea or constipation alongside grass eating indicate a potential digestive problem.
- Other concerning symptoms: Any new or worsening health signs should prompt a veterinary visit.
Practical Steps: What You Should Do
If you’re concerned about your dog’s grass-eating habits, there are several steps you can take, from observation to lifestyle adjustments, always with veterinary guidance.
Observe and Document
Begin by closely observing your dog’s behavior. Note down:
- How often they eat grass.
- The quantity of grass consumed.
- Whether it’s followed by vomiting or other symptoms.
- Any changes in appetite or energy.
- The type of grass they eat (if possible).
- Any recent changes in their diet, routine, or environment.
This information will be invaluable for your vet.
Address Boredom and Lack of Stimulation
If boredom seems to be a factor, enrich your dog’s daily life:
- Increase physical exercise: Longer, more varied walks can do wonders.
- Provide mental stimulation: Puzzle feeders, interactive toys, obedience training games, and new commands can engage their minds.
- Social interaction: More playtime with you or other dogs can reduce boredom and anxiety.
Review Their Diet
If a dietary deficiency, particularly fiber, is suspected, do not change your dog’s diet without consulting your vet. They can recommend appropriate adjustments, such as introducing a high-fiber dog food or specific supplements. If your dog is struggling with their appetite, understanding what you can give your dog to make her eat could also be discussed with your vet.
Protect from Environmental Hazards
Ensure your dog only has access to untreated grass. If you use lawn care products, keep your dog off the lawn for the recommended period. Consider creating a safe, designated outdoor space for them away from chemically treated areas.
Seeking Veterinary Advice
Ultimately, if you’re worried about your dog’s grass eating, or if it’s accompanied by any concerning symptoms, consulting your veterinarian is the most important step.
When to Call the Vet
Don’t hesitate to contact your vet if:
- Your dog suddenly starts eating grass excessively.
- They frequently vomit after eating grass.
- They show signs of illness like lethargy, diarrhea, constipation, or if they are sick and won’t eat.
- They are eating grass but refusing their regular food.
- You suspect they have ingested treated grass or are at risk for lungworm.
Your vet can perform a thorough examination, check for parasites, assess their diet, and rule out any underlying medical conditions. They are the best resource for tailored advice and treatment plans for your individual dog.
Conclusion
While your dog occasionally munching on grass is often a harmless and natural behavior, understanding the various reasons behind it and knowing what to do if your dog keeps eating grass is vital. Pay close attention to the frequency, quantity, and any accompanying symptoms. Most importantly, if you have any concerns about your dog’s health or their grass-eating habits, always consult your veterinarian. Their expertise can help you determine if it’s a benign quirk or a sign of an underlying issue, ensuring your beloved companion stays happy and healthy.
