Why Dogs Eat Grass & When to Worry


Normal Grass-Eating Behavior

For many dogs, eating grass is just a natural habit.

Wild dogs and wolves also eat plants occasionally.

Your dog might just like the taste and texture of grass.

It doesn’t always mean they are sick or lacking something.

  • Signs It’s Normal: If your dog eats grass sometimes, it’s likely a harmless habit. It’s normal if it doesn’t vomit or seem uncomfortable afterward. Dogs that chew grass without urgency, like they are grazing, are usually not sick.
  • Fun Fact: Grass-eating occurs in dogs of all breeds and ages. Even wild animals, like wolves and foxes, have been seen nibbling on plants.
  • Different Grazing Styles: Some dogs nibble slowly, savoring the taste. Others chew casually as they walk. These habits can show whether your dog is just curious or has a deeper need.
  • Seasonal Grazing: In spring and early summer, dogs eat more grass. The new grass is tender and smells fresh. Some dogs seem to enjoy the softer, sweeter grass during these seasons.

Real-Life Example: A Labrador owner saw her dog nibbling grass on walks.

It did not swallow it.

The dog seemed to enjoy the activity, like exploring, rather than needing to eat it.

Pro Tip: If your dog grazes on grass and has no symptoms, they may just find it fun.

Occasional grazing isn’t usually a problem.

Nutritional Deficiencies

Sometimes, dogs eat grass because they are missing something in their diet.

Grass has little nutrition.

Dogs may chew it for fiber or minerals.

This can happen more often if a dog’s diet is unbalanced.

  • Signs of Nutritional Deficiency: If your dog eats grass urgently, they may need a better diet. Dogs on diets low in fiber or missing key vitamins and minerals might feel the need to graze.
  • Diet and Grass-Eating: Dogs on high-protein, low-fiber diets may crave greens. They seek to balance their diet. Fiber helps with digestion, so a lack of it could make your dog more likely to eat grass.
  • Adding Fiber-Rich Foods: Talk to your vet about adding fiber-rich foods to your dog’s meals. Good options are carrots, apples (without seeds), and green beans. Balanced nutrition can help reduce the need for grazing.

Example: One dog owner noticed her dog chewing grass eagerly after meals. 

After adding more fiber to the dog’s diet, the grass-eating reduced.

Nutritional Supplements to Help with Grass-Eating

For dogs that graze due to nutritional needs, adding specific supplements can help.

These supplements can improve digestion.

They can provide missing nutrients and support health.

This reduces the need for grass.

  • Fiber Supplements: Fiber is important for digestion. If your dog isn’t getting enough fiber, they might turn to grass. Adding fiber-rich foods, like pumpkin and sweet potatoes, can help. You can also use a vet-recommended fiber supplement. They will support your dog’s digestion.
  • Probiotics support a healthy gut. They can reduce stomach upset. This might make your dog less likely to eat grass. These come in powders, capsules, or treats.
  • Omega-3 Fatty Acids: Omega-3s, in fish oil, reduce inflammation and support gut health. This may help nutrient absorption and stop discomfort that causes grass-eating.
  • Multivitamins: If your dog eats grass, they may lack vitamins. Daily multivitamins can help. Talk to your vet about the best options for your dog.

Example: One pet owner added fiber-rich pumpkin and probiotics to her dog’s diet.

She noticed the grass-eating habit significantly decreased.

Adding the right supplements and nutrition to your dog’s meals can help with some reasons for grass-eating.

Always check with your vet before adding new supplements.

They must be safe for your dog’s specific needs.

Digestive Upset or Nausea

One of the main reasons dogs eat grass is to ease stomach discomfort.

Dogs will sometimes eat grass to make themselves vomit if they are feeling nauseous.

The texture of grass irritates their stomachs, which can help them throw up and feel better.

  • Signs of Nausea: If your dog is nauseous, they may drool, lick their lips, pace, or seem restless. If they eat grass and vomit right after, they might be using the grass to settle their stomach.
  • What to Do If Your Dog Vomits After Eating Grass: If your dog vomits after eating grass, give them water. But, don’t feed them for a few hours. If the vomiting continues, or if your dog seems uncomfortable, contact your vet.
  • Alternative Greens: Some pet owners offer safe greens, like wheatgrass or parsley, as a substitute for grass. These can satisfy your dog’s urge to eat plants without causing vomiting. Always introduce new plants gradually.

Important Note: If your dog vomits often after eating grass, it’s a good idea to see your vet. 

Frequent vomiting could point to bigger health problems.

Anxiety or Boredom

Like humans, dogs can feel stress or boredom

Sometimes, this leads to behaviors like eating grass. 

If a dog lacks exercise or mental stimulation, it might eat grass to pass the time or relieve stress.

  • How to Recognize It: Dogs that graze because of stress or boredom may pace, pant, or whine. They might graze when they are alone or feeling under-stimulated. These dogs may not seem hungry but will still engage in grass-eating.
  • Boredom-Driven Grazing: If your dog lacks toys or mental stimulation, they might start grazing. Dogs often graze more when they are bored, especially if they are left alone in the yard without something to do.

Tips for Reducing Stress Grazing: Use toys, puzzle feeders, or exercise.

This can help reduce their stress and keep them busy, so they don’t turn to grass.

Pro Tip: If your dog’s eating grass due to stress, talk to your vet about calming supplements.

They might help.

When to Contact the Vet

It’s important to know when to call your vet.

While eating grass is usually harmless, there are times when it can be a sign of something more serious.

Persistent Symptoms: If your dog eats grass and vomits often, contact your vet.

If it seems uncomfortable, like having diarrhea, being tired, or losing its appetite, call your vet.

Grass-eating, plus these symptoms, might signal a bigger issue.

It could be gastrointestinal problems, allergies, or even parasites.

Red Flags:

  • Vomiting every time they eat grass
  • Diarrhea or blood in stools
  • Lethargy or weakness
  • Loss of appetite
  • Drooling or trouble chewing

Managing Grass-Eating Habits

While grass-eating is usually harmless, it can be managed.

  • Balanced Nutrition: Make sure your dog is getting a balanced diet. A good diet with the right amount of fiber can sometimes prevent the need for grass. Foods like pumpkin, carrots, and vet-approved supplements can be helpful.
  • Increase Mental Stimulation: More toys, puzzles, or playtime can reduce boredom. They will keep your dog occupied and stop grazing.
  • Create Grass-Free Zones: If your dog has a habit of grazing, consider creating a grass-free play area. Adding mulch or gravel in parts of your yard can reduce access to grass while still giving your dog a fun area to play.
  • Safe Grazing Alternatives: Give your dog safe, dog-friendly greens like lettuce or parsley. They will satisfy their grazing instincts.

Example: A pet owner created a grass-free section of her yard to limit her dog’s access to grass. 

This helped reduce her dog’s grass-eating habit.

Preventative Care for Grass-Eating Dogs

Grass-eating can expose your dog to parasites. 

This is especially true if they graze in public parks or areas with other animals.

  • Regular Fecal Exams: Schedule regular fecal exams with your vet if your dog eats grass often. This will help catch any parasites early.
  • Preventative Care: A dog that grazes often is more likely to catch bacteria or worms in the soil. Regular vet check-ups will help keep your dog safe and healthy.

Conclusion

Grass-eating is very common in dogs, and it’s usually nothing to worry about.
