Dog's Stomach Making Noises and Eating Grass: 5 Problems You Could Face

icon May 10, 2023

If you are a dog owner, you may have noticed your furry friend's stomach making loud, gurgling noises from time to time. It's not uncommon for dogs to experience stomach noises, but when combined with a sudden urge to eat grass, it can be a sign of an underlying issue.

In this article, we'll explore why dogs' stomachs make noises and why they may turn to grass for relief.

Why Is My Dog's Stomach Making Noises? Common Causes

A dog's stomach making noises often referred to as "stomach rumbling," is a common occurrence and is typically not a cause for immediate concern. However, persistent or excessive stomach noises may indicate an underlying issue. Here are some common causes of stomach noises in dogs:


  • The most common reason for stomach noises in dogs is hunger. When the stomach is empty, the digestive system produces sounds as it prepares for food intake.


  • Dogs can sometimes swallow air while eating or drinking quickly, leading to the formation of gas in the stomach and intestines. This can result in audible stomach noises.

Digestive Processes

  • The normal digestion and movement of food through the digestive tract can produce noises. These sounds are more noticeable when the dog's stomach is empty, during periods of digestion, or after eating certain types of food.

Dietary Changes or Intolerance

  • If you recently changed your dog's diet or introduced a new food, the stomach may produce noises as it adjusts to the change. Additionally, some dogs may have dietary intolerances or sensitivities that can cause increased digestive sounds.

Many dog owners find that when the dog's stomach grumbles, it likes to eat grass.

Is Eating Grass a Sign of Pica?
