My Dog Has Loose Stools and Smelly Gas: Causes and Solutions


If you’re a dog parent, you know that your furry friend’s digestive health is essential for their overall well-being.

So, when you notice that your dog has loose stools and smelly gas, it can be concerning.

In this blog post, we will explore the possible causes of these symptoms and provide you with some solutions to help your dog feel better.

Understanding Loose Stools and Smelly Gas in Dogs

Loose stools, also known as diarrhea, is a common problem in dogs. It is characterized by frequent bowel movements that are watery, soft, or unformed.

Smelly gas, on the other hand, is a result of the fermentation of undigested food in the intestines.

Both loose stools and smelly gas can be signs of an underlying issue in your dog’s digestive system.

Possible Causes of Loose Stools and Smelly Gas

  1. Dietary Changes: Abrupt changes in your dog’s diet can disrupt their digestive system, leading to loose stools and smelly gas. Introducing new food or treats too quickly can cause gastrointestinal upset.
  2. Food Intolerances or Allergies: Just like humans, dogs can develop intolerances or allergies to certain foods. Common culprits include grains, dairy products, and certain proteins. If your dog is sensitive to a particular ingredient, it can result in loose stools and smelly gas.
  3. Bacterial or Viral Infections: Infections caused by bacteria or viruses, such as Salmonella or Parvovirus, can lead to diarrhea and gas in dogs. These infections are often accompanied by other symptoms like vomiting and lethargy.
  4. Parasites: Intestinal parasites, such as worms or Giardia, can cause loose stools and smelly gas in dogs. Regular deworming and preventive measures can help keep these parasites at bay.
  5. Stress or Anxiety: Dogs are sensitive creatures, and stress or anxiety can affect their digestive health. Changes in routine, travel, or separation anxiety can lead to loose stools and smelly gas.

Solutions for Loose Stools and Smelly Gas

  1. Gradual Diet Transition: If you suspect that a sudden change in your dog’s diet is the cause of their digestive issues, try transitioning them to new food gradually. Mix a small amount of the new food with their current food and gradually increase the proportion over a week.
  2. Elimination Diet: If you suspect a food intolerance or allergy, consider putting your dog on an elimination diet. This involves feeding them a limited ingredient diet with novel proteins and carbohydrates to identify the trigger food. Consult with your veterinarian for guidance.
  3. Probiotics and Digestive Enzymes: Probiotics and digestive enzymes can help restore the balance of good bacteria in your dog’s gut and aid in digestion. These supplements can be beneficial in resolving loose stools and smelly gas.
  4. Medical Treatment: If your dog’s symptoms persist or worsen, it’s essential to consult with your veterinarian. They may recommend medication or further diagnostic tests to identify and treat the underlying cause.
  5. Stress Management: If stress or anxiety is the root cause of your dog’s digestive issues, try to identify and address the triggers. Providing a calm and secure environment, regular exercise, and positive reinforcement training can help alleviate stress in dogs.

Remember, every dog is unique, and what works for one may not work for another.

It’s crucial to work closely with your veterinarian to determine the best course of action for your furry friend.


Loose stools and smelly gas in dogs can be distressing for both you and your pet.

By understanding the possible causes and implementing appropriate solutions, you can help improve your dog’s digestive health.

Remember to consult with your veterinarian for personalized advice and guidance.
