Why do dogs eat grass?

All of us have seen our dogs happily grazing in our gardens, especially enjoying the uncut long grass on the edges.

  • Instinct. Dogs are omnivors, meaning they eat meat and plants. Although your dog shouldn’t need extra nutrients if he is eating a balanced diet, he might eat grass for its nutritional value.
  • Dogs eat grass to vomit. Many times you will note that your dog vomits after eating grass. But, veterinarians still aren't sure if dogs eat grass because their stomachs are upset or if their stomachs get upset after they eat grass. However, many vets suspect it's because their stomachs are upset, because dogs who are energetic and perky seem to be able to eat grass without getting sick afterward. It seems likely that there is something in grass that does stimulate the urge to vomit. If your dog eats grass then vomits and seems fine, he’s probably taken care of whatever was bothering him. If he keeps retching and is unable to throw up or keeps eating grass and carries on vomiting, you should take him to the vet.
  • Some dogs eat grass because they like the taste.

Is it harmful?

  • Grass is harmless unless consumed excessively.
  • Don’t let your dog eat grass that has been treated with pesticides, fertilisers or any chemicals. Most lawn-care products will indicate whether or not they’re safe for pets. Even if using “pet friendly” products you should keep your dog away from the grass soon after chemicals have been applied. Most products break down fairly quickly, but they can be quite dangerous if your dog eats them while they are fresh.
