1. Because they like the taste
A simple – but often overlooked – explanation is that some dogs simply enjoy the taste of grass. If your dog seems to chew grass regularly but shows no negative symptoms, it could be as simple as them liking the taste.

2. Try to vomit or deal with stomach upset
Many people believe that dogs eat grass to vomit when they feel sick. However, research shows that very few dogs actually vomit afterwards. If the behavior occurs frequently, it may be linked to mild stomach upset. Read more under Stomach & Digestion .

3. Inherited behavior from ancestors
Wolves and wild dogs also eat grass sometimes. It may be a biological behavior to cleanse the intestines of parasites. Please see our range of Parasite Protection for Dogs .

4. Lack of fiber in the diet
Grass eating can also indicate a fiber deficiency. A high-fiber feed or supplement can reduce the need to eat grass. Explore our products in Supplements & Health and Dog Food & Feed .

5. Exploration and play
Puppies and young dogs often explore the world with their mouths. Grass can be a curiosity-driven discovery. You'll find great options for mental stimulation in our Dog Toys category.

6. Should I let my dog eat grass?
A little grass every now and then is usually harmless. But avoid it if your dog vomits frequently, if the grass is sprayed, or if the behavior is excessive. Have you ever had to pull a long blade of grass out of your dog's butt? Then you know what we mean!

7. What can I do?
Consider whether your dog's needs are being met: fiber, stimulation, and health. Adjust the diet, offer more activities, and observe symptoms. Contact your veterinarian if you are unsure.

10. When should you act?
If grass eating occurs frequently, causes vomiting, or seems compulsive – then it's time to take action. Start by reviewing the diet and contact a veterinarian if necessary.
