Is It Normal for Puppies to Eat Grass?
Yes, it’s completely normal for puppies to eat grass. In fact, studies show that around 70-80% of dogs eat grass at some point in their lives. It’s a natural behavior that usually doesn’t indicate anything serious. While it can seem strange to us, dogs are omnivores by nature and sometimes crave plant material—even if their regular diet is meat-based kibble or canned food.
Top Reasons Puppies Eat Grass
Puppies may chew on grass for several reasons, some behavioral and some physical. Here are the most common explanations:
1. Curiosity and Exploration
Puppies are naturally curious. They use their mouths to explore the world, and grass is often just another texture and taste to sample.
2. Boredom or Playfulness
If your puppy isn’t mentally stimulated, they may turn to chewing on grass out of boredom. It becomes a form of play or entertainment.
3. Instinctual Behavior
Some dogs may eat grass instinctively due to their wild ancestors occasionally ingesting plant matter found in prey animals’ stomachs.
4. Upset Stomach
This is one of the most common theories. Some puppies may eat grass to induce vomiting if they have an upset stomach. However, not all grass-eating is followed by vomiting.
5. Nutritional Deficiencies
A puppy lacking fiber or certain nutrients in its diet may be drawn to grass as a supplement. However, this is relatively rare if your dog is eating a balanced commercial diet.
6. Attention-Seeking
If you react strongly every time your puppy eats grass, they may repeat the behavior just to get your attention—even if it’s negative.
Is Eating Grass Safe for Puppies?
In most cases, yes. Eating grass is generally considered safe for puppies—provided the grass hasn’t been treated with pesticides, herbicides, or fertilizers. These substances are toxic and can cause serious health problems.
Always be cautious about where your puppy roams and avoid letting them eat grass in public parks or landscaped areas unless you’re certain the area is chemical-free.
Can Eating Grass Make a Puppy Sick?
Grass itself typically won’t make a puppy sick, but there are exceptions:
- Vomiting: Some puppies vomit after eating grass, especially if they consume large amounts quickly.
- Parasites: Grass can carry parasites like roundworms or giardia if contaminated with other animals’ feces.
- Toxins: Lawn chemicals or poisonous plants can pose serious risks if ingested along with grass.
If your puppy eats grass frequently and vomits every time, or if you notice other symptoms like lethargy, diarrhea, or loss of appetite, it’s best to contact your veterinarian.
How to Stop a Puppy from Eating Grass
Here are a few tips if your goal is to curb your puppy’s grass-chewing habit:
- Redirect with toys: Carry a toy on walks and use it to distract your puppy from grass.
- Use commands: Teach basic commands like “leave it” or “no” to stop grass eating on cue.
- Increase mental stimulation: Puzzle toys, obedience training, and interactive games can reduce boredom-driven behavior.
- Review diet: Ensure your puppy’s food contains sufficient fiber and nutrients. Consult your vet for dietary adjustments if needed.
- Walk in clean areas: Avoid lawns treated with chemicals or areas frequented by many other animals.
When to Be Concerned
Grass eating in puppies is usually harmless, but contact your vet if:
- Your puppy vomits repeatedly after eating grass
- There are signs of gastrointestinal distress (diarrhea, gas, bloating)
- They’re eating large amounts of grass every day
- You suspect exposure to toxic substances or plants
Persistent or compulsive grass eating may be a sign of an underlying medical or behavioral issue worth investigating.
Frequently Asked Questions (FAQ)
Why do puppies eat grass and then throw up?
Some puppies may use grass to self-induce vomiting if they have an upset stomach, but not all grass-eating leads to throwing up. It could also be coincidental.
Should I stop my puppy from eating grass?
If the behavior is occasional and doesn’t result in vomiting or illness, it’s probably fine. However, if it’s excessive or compulsive, consult your vet.
Can eating grass cause worms in puppies?
Grass itself doesn’t cause worms, but it can be contaminated with parasite eggs or larvae from other animals. Always deworm your puppy as recommended.
Is it a sign of a dietary deficiency?
Possibly, but not commonly. Most puppies on a balanced diet won’t need extra fiber. Your vet can recommend tests if a deficiency is suspected.
What kind of grass is dangerous for puppies?
Any grass treated with fertilizers, weed killers, or pesticides is potentially toxic. Avoid allowing your puppy to graze in chemically-treated areas.
Final Thoughts
Why do puppies eat grass? It turns out the answer varies. Most of the time, it’s perfectly normal behavior caused by curiosity or habit. But in certain cases, it can signal boredom, dietary issues, or gastrointestinal discomfort. The key is to monitor how often it happens, check for signs of illness, and make sure your puppy’s environment is safe.
If in doubt, your veterinarian is the best resource to help determine whether your puppy’s grass-eating is harmless or needs further attention. With the right care and awareness, you’ll keep your furry friend happy, healthy—and out of the garden.
