Can Probiotics Help Stop Dogs From Eating Poop?

If your dog eats poop, you are definitely not alone. Coprophagia—the veterinary term for eating feces—is surprisingly common in dogs. And yes, it can be one of those habits that leaves pet parents wondering, “Why on earth does my dog think that’s a snack?” There are plenty of products, supplements, and home remedies marketed as ways to stop dogs from eating poop. Probiotics often come up in that conversation because gut health and digestion are closely connected to what happens in your dog's stool. But can probiotics actually make a dog stop eating poop?

Possibly in some situations, but there isn't strong scientific evidence that probiotics directly stop coprophagia. Probiotics may support digestive and gastrointestinal health, especially when a dog has certain digestive issues, but poop eating can have many different causes. That distinction matters.

Let's look at where probiotics might fit—and where they probably won't.

Why Do Dogs Eat Poop in the First Place?

Before reaching for a probiotic chew, it helps to think about why your dog is eating poop. Sometimes the reason is simply behavioral. Puppies, for example, naturally investigate the world with their mouths. Some dogs are also enthusiastic scavengers and learn that grabbing something from the ground gets them a rewarding experience. Other dogs may eat feces because of boredom, lack of stimulation, habit, or competition around food. There can also be medical reasons. Veterinary sources note that gastrointestinal problems, poor nutrient absorption, parasites, underfeeding, and other conditions that affect appetite or digestion can contribute to coprophagia. That's why persistent or sudden poop eating shouldn't automatically be treated as a behavioral quirk.

Merck Veterinary Manual also recommends ruling out medical causes before assuming a dog's feces-eating behavior is purely behavioral. So the first question isn't necessarily, “Which supplement stops my dog from eating poop?”

It may be: “Why did my dog start eating poop?” That question can lead you toward a much more useful solution.

Where Do Probiotics Come Into the Picture?

Probiotics are live microorganisms intended to provide a health benefit when consumed in adequate amounts. In dogs, researchers have studied probiotics for different gastrointestinal concerns, including stool quality, diarrhea, and changes in the intestinal microbiota. And there is some evidence that particular probiotic strains or combinations can influence canine gut health. For example, a randomized, placebo-controlled study involving dogs with acute diarrhea found that a specific probiotic combination helped normalize stool consistency and was associated with changes in certain bacteria found in feces. Another study found that a probiotic and prebiotic combination could influence fecal microbial populations in healthy dogs. That sounds promising, but there's an important catch:

Improving digestive health is not the same thing as stopping poop eating.

The evidence for probiotics in canine gastrointestinal health is still mixed, and researchers have emphasized that probiotic effects can vary considerably depending on the specific strain, formulation, condition, and dog being studied. A systematic review of probiotics for gastrointestinal disease in dogs found limitations in the available research, including small sample sizes and moderate-to-high risk of bias in many studies.

In other words, you shouldn't expect a probiotic chew to magically switch off a dog's interest in poop.

Can Better Gut Health Make a Difference?

This is where probiotics may have a reasonable role. A dog with digestive upset may have changes in stool consistency, appetite, digestion, or intestinal bacteria. If an underlying digestive problem is contributing to unusual eating behavior, addressing that problem could potentially help. There is also a practical reason pet parents consider probiotics: they can be part of a broader approach to maintaining normal digestive function.

Some canine studies have found that probiotic supplementation can affect fecal microbiota or stool characteristics. For instance, research on fiber, prebiotic, and probiotic blends has reported changes in stool quality and fecal microbial populations in healthy dogs. But it's important not to jump from that finding to “probiotics stop coprophagia.” The research doesn't establish that connection. Think of probiotics as gut-support tools, rather than poop-eating cures. That distinction keeps expectations realistic.

What About Kaiivo Probiotic Herbal Chews?

This is where a product like Kaiivo probiotic herbal chews can naturally fit into a dog's everyday wellness routine. Kaiivo's positioning centers on plant-powered daily wellness, with an emphasis on natural ingredients, gentle herbal support, and everyday pet care. The probiotic herbal chews are specifically positioned around gut health and digestion, with the tagline “Herbs in, tummy troubles out!”

According to the product formulation provided, two soft chews contain a probiotic blend providing a minimum of 10 billion CFU, along with inulin, FOS, oligogalactose, pumpkin, papaya, omega-3, vitamin E, yucca, chamomile, yam, and calendula. That combination gives the product a much more natural connection to this topic than claiming it is specifically a “poop-eating stopper.” The better message is: If your dog eats poop and also has digestive concerns, supporting normal gut health may be worth discussing with your veterinarian.

Kaiivo's product information describes the probiotic herbal chews as supporting gut health and digestion rather than as a veterinary treatment. That's an important distinction.

Probiotics Aren't a Substitute for Finding the Cause

Imagine your dog suddenly starts eating poop after years of never doing it. Giving a probiotic might be part of the conversation, but it shouldn't be the whole conversation.

Your veterinarian may want to look at your dog's diet, stool quality, appetite, weight, digestive symptoms, parasite risk, and overall health. VCA specifically notes that stool testing for parasites is a minimum part of the evaluation when medical causes are suspected. This is especially important if poop eating comes with other changes such as:

• persistent diarrhea or unusually soft stools
• vomiting
• weight loss
• unusually strong hunger
• poor growth in puppies
• changes in appetite
• lethargy
• signs of abdominal discomfort

These aren't problems that should simply be covered up with a supplement. For example, Merck Veterinary Manual notes that malabsorption can cause weight loss and altered appetite, and some affected dogs can show excessive hunger or coprophagia. Treating the underlying problem is much more important than trying to make feces taste unpleasant.

What Else Can Help Stop a Dog From Eating Poop?

Even if you're using a probiotic for digestive support, you'll probably want to tackle the behavior itself. And honestly, management can be surprisingly effective.

Start by picking up poop quickly. If your dog can't get to it, your dog can't eat it. Merck Veterinary Manual recommends preventing access to things a dog is trying to ingest when the behavior cannot be actively supervised. During walks or backyard time, stay close enough to redirect your dog. A simple “leave it” cue can become incredibly useful when paired with a reward your dog actually cares about.

You can also make meals more mentally engaging. Food puzzles, interactive feeders, training games, sniffing activities, and regular play can give dogs something more interesting to do than searching the yard for questionable snacks. And try not to turn poop eating into a huge dramatic event.

Some dogs learn that grabbing something disgusting instantly gets their owner's full attention. Calmly interrupting the behavior and redirecting the dog is usually more useful than chasing them around the yard.

Do Commercial Products Actually Work?

This is another area where it's worth keeping expectations in check. A study published in Veterinary Medicine and Science evaluated commercial products and behavior modification approaches marketed for canine coprophagia. The researchers reported very low overall success rates for the products and behavioral approaches they evaluated. That doesn't mean every product is useless. It means there isn't good evidence that a single supplement or additive reliably solves coprophagia in every dog. That's why a combination approach makes more sense: investigate potential medical causes, support normal digestion when appropriate, manage access to feces, and work on the behavior itself.

So Can Probiotics Help Stop Dogs From Eating Poop?

The short answer is: Probiotics may support digestive health, but they have not been proven to directly stop dogs from eating poop.

If your dog's coprophagia is related to an underlying digestive problem, improving gastrointestinal health could potentially be one piece of the puzzle. But if the behavior is mainly driven by scavenging, boredom, habit, exploration, or learned behavior, a probiotic alone is unlikely to fix it. That's actually good news, because it means you have more than one tool available. A sensible approach might look like this:

Check the health side → support normal digestion when appropriate → manage access to poop → redirect the behavior → reward better choices.

For pet parents who want to add a daily digestive supplement, Kaiivo probiotic herbal chews provide a probiotic blend plus prebiotic ingredients such as inulin, FOS, and oligogalactose, along with pumpkin and selected botanical ingredients.  But the goal should be supporting your dog's everyday gut health, not promising that a chew will make poop suddenly irresistible to ignore.

And if your dog has suddenly developed a serious poop-eating habit, especially alongside digestive or appetite changes, a conversation with your veterinarian is a much better first step than simply adding another supplement. After all, sometimes the poop isn't really the problem. It's the clue.
