Why Your Dog Eats Grass: Common Reasons and What It Means

Why Your Dog Eats Grass: Common Reasons and What It Means

A very common question that many pet owners ask is “why does my dog eat grass?” which can be quite distressing; with many people assuming the worst or that their beloved four-legged friend might be sick.

Here at Pet Tags UK, we love dogs just as much as you do. We don’t just sell engraved dog tags; we hope to be a place you can visit to get to know more about your pets, their health, their habits and ways to make life a pet owner more interesting, too, as well as spoiling them!

Today, we’re going to look at exactly why so many dogs eat grass and what it means for you.

First and foremost, it’s important to understand that this is very common, across all dogs, all ages, sizes and breeds.

Secondly, there is a medical name for it: Pica, which means eating something that isn’t food. While this could be an indication that something awry is up with your pooch, this isn’t always the case.

The eating and chewing of grass is thought to be a natural habit that dogs have, particularly since such a large percentage of pups and dogs have a good old chew in the garden.

However, there are a number of other possibilities, too.

  1. Many cats eat grass as a means of making them vomit. This is often done to evacuate the stomach of fur, feathers, bones and more. Some people believe that dogs eat grass for a similar reason – like when they have a stomach ache.
  2. Another suggestion for dogs eating grass is that it improves digestion by being an additional source of fibre in their diet. If your dog eating grass upsets you, you could try putting them on a diet with higher amounts of fibre than previously.
  3. Another reason your dog could be eating grass is that they like the way it tastes.

Many other people believe that dogs eat grass out of boredom, with a need to chew. If you think this is the case, why not invest in some chew toys and spend more time being active with your pet.

While it can be distressing, especially if eating grass does make your dog sick, it is important to note that it isn’t causing any harm to your pet. However, if you treat your lawn with pesticides or other chemicals, then we would recommend you keep your dog safely out of reach.

Whether your pampered pooch is poorly or not, treat them to something extra special – our range of engraved dog tags are the perfect addition to your dog’s collar. 

When Should You Worry?

  • Excessive grazing

  • Frequent vomiting

  • Signs like lethargy, appetite loss, diarrhea, or constipation

These may signal digestive, nutritional, or behavioural issues. Consult your veterinarian for personalised guidance .


Supporting a Healthy Balance

  • Provide a high-fibre, balanced diet or add safe options like pumpkin

  • Increase play and mental enrichment with walks, toys, puzzle feeders

  • Offer personal wheatgrass indoors as a clean, appealing alternative

  • Supervise outdoor time; keep dogs off chemically treated grass and avoid seed hazards

Final Thought

Grass-eating is typically innocent—but it can reveal your dog’s instincts, dietary needs, or boredom. With nutritious food, engaging activities, and vet checks when needed, you can keep your companion healthy and happy—without worry.
