Because every dog deserves the chance to feel better—and every pet parent deserves a simple place to start.
Why We Created Perfect Poop
Bernie’s Diarrhea Story: Why We Created Perfect Poop
When our dog Bernie struggled with loose, watery stools, we knew firsthand how stressful—and honestly, embarrassing—it could be. Wiping his fluffy fur, dealing with ruined rugs, and worrying about whether he felt okay became part of daily life.
We tried the digestive products available to us, but nothing felt simple or complete. Keeping up with multiple supplements and opening bottle after bottle at every meal was costly and frustrating. Many powders stuck to Bernie’s bowl, leaving much of the product uneaten and wasted.
Why Quick Fixes—and Medication Alone—Weren’t Enough for Bernie
For Bernie, some quick fixes helped in the moment, but they did not give him the consistent digestive support he needed day after day. His loose stools kept coming back.
Medication can be important when a veterinarian identifies an underlying issue. But we learned that Bernie also needed daily support for the foundation of his digestion—not just a temporary answer to a recurring problem.
Why Bernie’s Diarrhea Kept Coming Back
As we searched for answers, we found products with individual ingredients that seemed to help: fiber for stool consistency, probiotics for gut balance, or enzymes for digestion. But on their own, those products did not provide the lasting support Bernie needed.
We partnered with Ph.D. veterinary science researchers, formulation experts, and ingredient specialists to create a more complete solution. The turning point in Bernie’s diarrhea journey came from combining four key digestive essentials in one easy daily topper: fiber, prebiotics, probiotics, and digestive enzymes.
Perfect Poop is the product we wished we could have found for Bernie—thoughtfully made to support healthy digestion and more consistent stools, every day.
What Ingredients Can Help Diarrhea?
Why Fiber Can Help Dogs Suffering From Diarrhea
Fiber is helpful when trying to help your dog’s diarrhea because it can bulk up his stool up and absorb excess liquid in the colon. This may prevent the onset of diarrhea in a couple of ways. The insoluble fiber in Bernie’s is what bulks the poop up and helps give it a firmer shape. The soluble fiber helps slow digestion of food down in your dog and this is important because it allows your dog to get the full benefit from the nutrients and vitamins you’re giving them. Not only does the right combination of insoluble and soluble fiber help prevent diarrhea, constipation and slow digestion, but it also lowers the pH level in your dog’s gut and stimulates the growth of beneficial bacteria. Fiber fermentation in your dog’s gut produces beneficial fatty acids that supplies energy to every cell in your dog’s body, and is a frontrunner when it comes to stopping the runs.
Why Do Pet Parents Look for Both Prebiotics & Probiotics for Diarrhea
Prebiotics and probiotics are key supplements to helping your dog’s gut health be at its best. Prebiotics and probiotics balance out your dog’s digestive tract bacteria and microbiome. This means your dog is able to produce firmer, less stinky poop. The prebiotic in Bernie’s is Inulin, which acts as a fertilizer to feed the good bacteria in your dog’s lower digestive tract. Working with the power of fiber reducing your dog’s gut pH level, the Inulin helps offer good bacteria nutrition they need to thrive. When they thrive and keep your dog’s gut healthy and balanced, you may see the end of diarrhea.
Probiotics are the good bacteria in your dog’s gut. When you add good bacteria through supplementation, you’re helping your dog achieve good dog gut health by getting rid of the bad bacteria that causes colitis, leaky gut and diarrhea. With proper nutrition from probiotics, the good bacteria probiotics also flourish and may help keep your dog’s gut able to fight off virus, allergens, inflammation and poor nutrient absorption. , When we add good bacteria with Bernie’s, we help achieve good dog gut health, which lends itself to helping prevent diarrhea.
Why Do Enzymes Matter for Dogs With Diarrhea?
Enzymes in Bernie’s Perfect Poop will help your dog’s digestive tract break food down better. Your dog’s digestive system is detailed and involves several organs. But, the most important reason you want to be sure your dog has good enzymes is that that’s what keeps the good bacteria in their gut fed well too. The healthier that system, the better your dog’s digestion will be and the better able he’ll be to create the perfect poop.

Why Dog Parents Choose Perfect Poop for Digestive Support
Our Golden has had many gastro issues since we got him. At least once or twice a week he’d have horribly liquid stools, but no other issues. We’ve done numerous food changes, probiotics, dehydrated carrots, pumpkin…..everything we or the vet could think of to try. It’s been a month since we tried this stuff and as they say……Perfect Poop! It’s been magic so far! – Jeanine

Warning: If Your Dog Has Diarrhea
If your dog has diarrhea, it’s important to monitor it closely and help prevent dehydration. Occasional mild diarrhea may resolve on its own, but ongoing diarrhea can lead to fluid loss, discomfort, and more serious complications—especially in puppies, senior dogs, or dogs with existing health conditions.
Contact your veterinarian promptly if diarrhea lasts more than 24–48 hours, is frequent or severe, contains blood, is accompanied by vomiting, lethargy, loss of appetite, or signs of dehydration, or if your dog seems to be in pain. Persistent diarrhea can signal an underlying issue that needs veterinary care.
