Why does my dog have soft stools? Causes, solutions, and diet

Why does my dog have soft stools? The complete veterinary guide to understanding, acting on, and permanently preventing digestive issues

Why is this article essential?

Your dog's stools are a true indicator of their digestive health. A change in their appearance, frequency, or consistency may sometimes be benign, but it can also reveal a dietary imbalance, a change in routine, a parasite, an intolerance, or an illness requiring veterinary advice.

Many owners immediately look to change their kibble when they notice soft stools. However, the reality is often more complex. Understanding the causes allows you to act appropriately and avoid constant dietary changes, which can sometimes aggravate the situation.

In this complete guide, we will explain:

• why a dog has soft stools;
• how to distinguish a normal situation from a problem requiring a veterinary consultation;
• which dietary errors are most common;
• how to promote good digestion through a balanced diet;
• how to prevent recurrences.

Our goal is to help you make the best decisions for your companion by relying on canine nutrition principles recommended by leading veterinary organizations.

 

 

What exactly are soft stools?

A dog’s normal stools are generally:

• well-formed;
• easy to pick up;
• medium to dark brown in color;
• not very odorous;
• regular.

Conversely, soft stools are less compact, wetter, and may lose their shape. They are not always synonymous with diarrhea.

We generally distinguish between:

• Slightly soft stools: still formed but less firm.
• Very soft stools: difficult to pick up.
• Diarrhea: liquid, frequent stools, sometimes accompanied by mucus or blood.

This distinction is important because the causes and the necessary steps to take can differ.

Why are stools an excellent indicator of health?

The dog’s digestive tract plays several essential roles:

• digesting food;
• absorbing nutrients;
• hosting a complex intestinal microbiota;
• contributing to the proper functioning of the immune system.

When digestive balance is disturbed, stools are often the first visible sign.

This is why veterinarians almost always ask about:

• how long the problem has been occurring;
• how often the dog defecates;
• the color of the stools;
• their texture;
• the possible presence of mucus or blood;
• recent changes in diet.

The 12 most common causes of soft stools in dogs

1. A dietary transition that is too fast

This is likely the most common cause.

The intestinal microbiota needs several days to adapt to a new recipe.

Changing kibble abruptly can cause:

• soft stools;
• gas;
• bloating;
• a decrease in appetite in some dogs.

A gradual transition over several days is generally recommended to give the digestive system time to adapt.

 

 

2. A diet that is not very digestible

Not all kibble has the same level of digestibility.

A quality recipe is based on:

• quality animal proteins;
• a good nutritional balance;
• carefully selected raw materials;
• rigorous manufacturing.

Low digestibility can lead to a larger quantity of residue in the stools.

At Pavllove®, our recipes are developed in Auvergne with carefully selected ingredients, controlled cooking, and animal proteins that remain the primary ingredient after cooking. Our goal is to offer a naturally palatable diet, adapted from puppy to senior dog, promoting good digestibility as part of a balanced diet.

 

3. Excess treats

Even quality treats should be given in moderation.

Common mistakes are:

• giving too many rewards;
• frequently giving table scraps;
• offering several different products in the same day.

The digestive system appreciates consistency.

 

4. Repeated dietary changes

Switching from one brand to another every week is rarely a good idea.

Each recipe has its own nutritional balance.

The intestinal microbiota may need time to regain its stability.

5. Stress

Moving, traveling, staying at a kennel, the arrival of a new animal, or a change in habits can disrupt transit.

In some dogs, stress directly influences intestinal motility.

6. Digestive parasites

Intestinal parasites can cause:

• soft stools;
• diarrhea;
• weight loss;
• sometimes vomiting.

A veterinary diagnosis is necessary to identify the cause and implement appropriate treatment.

 

 

When should you consult a veterinarian quickly?

Even if isolated soft stools can sometimes be linked to a temporary dietary mistake, certain signs should prompt a quick consultation:

• presence of blood in the stools;
• significant diarrhea lasting more than 24 to 48 hours in an adult dog;
• a puppy with diarrhea;
• associated vomiting;
• severe fatigue;
• refusal to eat;
• abdominal pain;
• dehydration.

These situations require a clinical examination to determine the cause.

Things to remember

Soft stools are not a disease in themselves. They are a symptom that deserves to be interpreted in context. An adapted diet, a gradual transition, a healthy lifestyle, and veterinary follow-up when necessary are the best foundations for preserving a dog’s digestive health.
