What Causes Loose Stool In Dogs?

During these times, it is best to change your fur baby’s diet. Looking for the best dog food for firmer poop is a must if you want to save your pup from having runny, loose stool.

Neglecting to give your dog a healthier diet can lead to parasitic attacks that can potentially cause a loose stool. An allergic reaction from food can also lead down that path. Though most allergic reactions affect the eyes, nose, and skin, they can still also affect a dog’s digestive tract.

To give you more idea, here is a list of additional causes that can loosen your dog’s stool:

Dietary Changes

If you recently switched your dog’s food to a new type, their digestive system might need time to adjust and get used to it. It can result in a loose stool.

Poor Food Choices

Dogs eating dirty food or leftovers from strangers can increase the risk of loose stool. They could either rampage the trash for scraps or eat leftovers that someone played with within a nearby stall or restaurant.

Eating Poisonous Materials

Another likelihood for loose stools and upset stomachs is eating or ingesting poisonous materials like insecticides or toxic plants.


Diseases are another common cause of loose stools in dogs. Several digestive ailments and conditions can lead to diarrhea.


As implied, diarrhea is correlated to loose stools. Certain medications can induce diarrhea as part of their side effects. You must strictly follow the vet’s medical advice and prescription.

Emotional Upsets

Lastly, dogs are similar to humans in several ways. One such likeness is the ability to feel and express emotions. Dogs can also suffer from stress, depression, and anxiety. In some cases, emotional distress and problems are associated with loose stools and constipation. 

What To Consider When Buying Dog Food For Firmer Stool

The moment you notice that your dog is experiencing a loose stool, you must take urgent action. In most instances, you can address this issue by giving them the right dog food to firm up their stool.

Here is a brief outline and overview of what you need to consider if you are looking for dog food for firm stools.

Natural Ingredients

The secret to a healthy and happy pup is giving them food with natural ingredients. Dogs do not have an evolved enough digestive system (neither do humans, frankly) to break down large amounts of man-made and processed food without any issue. Unnatural fillers like artificial flavors and preservatives can increase undigested residue and gas.

Go for No or Quality Grains

Consider no grain dog food to help firm your dog’s stool fast. Although, most brands today contain some level of grains that are used to give additional carbohydrates, so it can’t be avoided completely. In those cases, go for whole-grain-based foods for easy digestion.

Fiber Components

Fiber is a crucial ingredient you need to seek out since it is technically the building block of the digestive system. It also promotes the absorption of excess water. Ensure that the dog food you plan to buy has high fiber content to encourage better nutrient absorption and digestion.

Low-Fat Content

Fats are complex ingredients that are hard to break down and digest, especially if they come in large quantities. Therefore, look for food that uses low or average fat content. 20% is the acceptable ratio.

Vitamins and Minerals

Loose stool and stomach problems can root in diseases. If that were the case with your dog, aim to strengthen their immune system and ability to fight off infections and viruses.

Look for food with essential vitamins and minerals. Enough supply of these can improve their ligaments, bones, and teeth. Certain minerals, especially magnesium and phosphorus, must be carefully balanced since high quantities may lead to bladder stones.


A canine’s digestive system contains several helpful bacteria that aid food digestion. Dog food rich in probiotics can add beneficial bacteria, which will help maintain a healthier gastrointestinal tract.

Other Enrichments

Aside from the ingredients above, there are other enrichments you need to consider for your pet’s food. Taurine, for example, can help the development of the brain and eye cells.
