Happy Pup, Happy Gut: Prebiotic Fiber for Dogs

What You Will Learn

• How fiber supports canine gut health.
• Why dogs need healthy gut bacteria.
• How fiber supports healthier poops.
• Ways to share just better.® with your pup.

August is National Dog Month, and the JUST BETTER BRANDS rescue pup C-Suite has an important announcement: Fiber is for dogs, too! 🐶🐾

Dogs have their own community of bacteria and other microorganisms living in the digestive tract. Together, these microorganisms form the canine gut microbiome. A balanced gut microbiome supports healthy digestion, immune function, nutrient metabolism, and the intestinal barrier.

Diet, age, stress, illness, medications, and other factors can influence this delicate community. Giving beneficial gut bacteria the nourishment they need is one way pet parents can support a happy pup gut.

Naturally, our favorite way to help is with prebiotic fiber!

What Does Prebiotic Fiber Do for Dogs?

Prebiotic fiber travels through the digestive system and becomes nourishment for beneficial bacteria in the colon. As these bacteria ferment fiber, they produce compounds called short-chain fatty acids that help nourish the cells lining the colon and support a healthy intestinal environment.

This activity can help support:

• A balanced canine gut microbiome

• Healthy digestion and regularity

• Stool quality and consistency

• The intestinal barrier

• Immune health

Research into canine nutrition continues to show the importance of dietary fiber and prebiotics for the gut microbiome. A recent study focused specifically on soluble corn fiber found improvements in canine fecal scores, along with changes in gut microbial composition and several short-chain fatty acids.

That is good news for pups, pet parents, and everyone assigned to poo patrol!

Healthy Gut, Healthier Poops

Your dog’s poop can reveal quite a bit about their digestive health. Ideally, bowel movements should be well-formed, consistent, and easy to pick up.

Fiber helps manage water in the digestive tract and supports healthy stool formation. The right amount can help create firmer, tidier bowel movements that are much easier to manage when cleanup time arrives.

We consider that a win for the entire household. 💚

Changes in your dog’s poop can have many possible causes. Frequent diarrhea, constipation, blood, mucus, straining, or sudden changes in bathroom habits deserve a conversation with your veterinarian.

Bring On the Anti-Scoot!

Every dog parent knows the move: backside on the floor, front paws in position, and away they go!

Scooting can happen when a dog experiences itching, irritation, parasites, allergies, or problems with the anal glands. It deserves veterinary attention when it happens frequently or comes with licking, swelling, odor, discomfort, or visible irritation.

Healthy, well-formed stools may help the anal glands empty naturally during bowel movements. Supporting healthy stool quality can make fiber a helpful part of an anti-scoot nutrition plan when approved by your veterinarian.

Here’s to happy bellies, healthier poops, and fewer surprise performances across the living room rug! 😉

Every Pup Deserves a Happy Belly

Our dogs give us unconditional love, joyful greetings, comforting cuddles, and plenty of reasons to laugh. Caring for their gut health is one meaningful way we can return some of that love.

During National Dog Month, consider adding just better.® prebiotic fiber to your pup’s meals or treats. A little extra support for their gut may lead to a happier belly, healthier poops, easier cleanup, and a stronger anti-scoot strategy. 

Life is just better.® with dogs! 🐶🐾💚
