Choosing the Best Dog Foods for Firm Stools: A Buyer's Guide

Using Natural Ingredients to Firm Up Dog Stools

Firm stools are a sign of a healthy dog, but not all dogs have the same digestive needs. Dogs with sensitive digestive systems require higher-quality foods that contain natural ingredients.

These ingredients are easier for a dog’s digestive system to process, as they are closer to what dogs would consume in the wild.

Avoiding Artificial Preservatives, Colors, and Additives

Artificial preservatives, colors, and additives can agitate sensitive dogs, so it’s important to avoid them. Ingredients such as butylated hydroxyanisole or ‘Blue 2’ or ‘Red 40’ should be avoided. Instead, look for kibbles with natural ingredients to promote a healthy digestive system.

Prebiotic Fibers and Probiotics

Prebiotic fibers add bulk to stools, which can help reduce diarrhea and promote firmer stools. They can be found in wholesome veggies, fruit, and grains, such as bananas, chickpeas, chicory root, and oatmeal.

Probiotics are beneficial microorganisms that consume prebiotic fiber and help promote healthy digestion. Look for kibbles that contain lactobacillus acidophilus and bifidobacterium animalis fermentation products, as they provide live yogurt cultures with every bite.

Finding the Right Amount of Fiber

Fiber is a key component in a dog’s diet, but it’s important to find the right amount for your dog. Too much or too little fiber can cause digestive issues.

If your dog has runny stools, consult with your veterinarian to determine if a higher fiber diet is appropriate. On average, most kibbles contain 2% to 5% fiber, while a high-fiber diet is anything between 6% and 12%.

Choosing the Right Protein

If your dog is allergic to certain proteins, it’s important to find a protein source that works best for them to avoid digestive issues.

Limited-ingredient diets that incorporate lamb can be a good option for dogs with sensitive digestive systems, as it is easier to digest. Additionally, dogs with difficulty digesting high-protein kibbles may benefit from kibbles with lower protein content.

Using Yucca Schidigera Extract to Reduce Odor

Yucca schidigera extract is a herbal plant that can help reduce the odor of dog waste in high-quality kibbles. It can reduce the odor by up to 26%. Look for kibbles that list this ingredient to help reduce the smell of your dog’s poop or gas.


1. What should I avoid when choosing dog food to prevent runny stools?

To prevent runny stools, it’s important to avoid foods that contain artificial ingredients, especially preservatives, colors, and additives.

These ingredients can irritate your dog’s digestive system and cause allergic reactions. Instead, look for foods that contain natural ingredients and avoid those that contain these ingredients.

2. Can a high-fiber diet help promote firm stools in dogs?

Yes, a high-fiber diet can help reduce diarrhea and promote firmer stools in dogs. Look for foods that are high in fiber, but do not overfeed your dog as this may cause bloating and indigestion.

3. Can switching to a limited-ingredient diet help with runny stools?

Yes, switching to a limited-ingredient diet can help reduce the occurrence of runny stools. If your dog is unable to digest certain ingredients, a limited-ingredient diet can help eliminate these triggers.

Choose foods with simple ingredients that do not contain ingredients that may cause allergic reactions.

4. Should I consult with my veterinarian before changing my dog’s diet to promote firm stools?

Yes, it’s important to consult with your veterinarian if your dog experiences runny stools. They can help you determine the best course of action for your dog’s health and well-being.

Your veterinarian may recommend specific foods or dietary changes that can help promote firmer stools in your dog.

5. Does eating bananas help to firm up dog stool?

Yes, bananas are high in fiber which can help with gastrointestinal issues in dogs and promote healthier bowel movements.

6. Can carrots contribute to firmer stool in dogs?

Yes, carrots are a good source of fiber and can help regulate your dog’s bowel movements, contributing to a healthy digestive system and firmer stools.
