Why Does My Dog Eat Grass?

by | Sep 7, 2023

Why does my dog eat grass?


Dogs eating grass is a relatively common behaviour, and while the exact reasons for this behaviour aren’t fully understood, several theories exist to explain why dogs might consume grass:



  1. Digestive Upset: One of the most widely accepted theories is that dogs may eat grass when they have an upset stomach. Grass could induce vomiting, helping them expel something that’s bothering their digestive system.


  1. Dietary Instinct: Dogs’ ancestors, such as wolves, were omnivores and might have consumed plants as part of their diet. This instinct could lead some dogs to consume grass, even though they are primarily carnivores.


  1. Fibre Intake: Dogs might eat grass to add more fibre to their diet. If they are lacking fibre, they might be instinctively drawn to consuming plants like grass to compensate.


  1. Boredom or Anxiety: Dogs might eat grass out of boredom or anxiety. Chewing on something can be a way for them to alleviate stress or occupy themselves.


  1. Pica Behaviour: Pica is a term used to describe the consumption of non-food items. Some dogs might exhibit pica behaviour, which could lead them to eat grass or other non-edible objects.


  1. Taste and Texture: Grass might simply taste good to some dogs, or they might be attracted to the texture. Dogs explore the world through their mouths, so it’s possible that grass appeals to their senses.


  1. Nutritional Deficiency: In some cases, dogs might eat grass if they’re lacking certain nutrients in their diet. They may be trying to supplement their nutritional needs by consuming plant material.


  1. Medical Reasons: Sometimes, underlying medical issues like gastrointestinal disorders or parasites can cause dogs to eat grass as a response to discomfort.


It’s important to note that occasional grass consumption might not be a cause for concern. However, if your dog is eating large amounts of grass frequently or exhibits other unusual symptoms, it’s recommended to consult with a veterinarian. If the behaviour is a result of a medical issue or dietary imbalance, the vet can provide appropriate guidance and treatment.
