Coprophagia — the scientific name for a dog eating its own or another animal’s stool — is one of the most frustrating and unhygienic habits a pet owner can face. While the behavior can stem from boredom, nutrient deficiency, or simple instinct, the fix isn’t a punishment, but a carefully formulated supplement that makes the stool itself taste and smell unappealing. The right blend of enzymes, probiotics, and natural deterrents can break the cycle without stress.
I’m Mohammad — the founder and writer behind ProteinJug. I have spent years analyzing pet supplement formulations, comparing enzyme concentrations, probiotic counts (CFUs), and natural deterrent ingredients like yucca schidigera to separate what actually works from what is just clever packaging.
After cross-referencing hundreds of verified buyer reports with ingredient lists and potency data, I have narrowed the market down to five leaders. If you are looking for a supplement to stop dog from eating poop, these chews represent the most effective strategies for breaking the stool-eating cycle.
How To Choose The Best Supplement To Stop Dog From Eating Poop
Not all poop-eating deterrents are formulated the same. Some rely on a single active ingredient, while others use a multi-pronged approach that addresses the root cause. Here are the three critical factors to evaluate before buying.
Enzyme & Probiotic Potency (CFU & Blend)
The most effective supplements don’t just mask the stool’s smell — they improve the dog’s digestion so the stool itself is less appealing. Look for a blend that includes protease, amylase, and lipase (digestive enzymes) alongside a high colony-forming unit (CFU) count of probiotics. A formula with 6 Billion CFU, as seen in premium options, provides a robust gut-health foundation that naturally reduces the urge to scavenge.
Natural Deodorizing & Deterrent Agents
Ingredients like yucca schidigera and pumpkin fiber work by reducing the odor of the stool from the inside. Since dogs are often attracted to the scent of partially digested proteins in feces, a supplement that neutralizes that smell makes the pile uninteresting. Parsley and chamomile are also common additions that help freshen the dog’s breath while contributing to the overall deterrent effect.
Chew Form & Palatability
If your dog refuses to eat the supplement, the formulation is useless. Soft chews with real meat flavors (chicken, beef liver, duck) are significantly easier to administer than hard tablets or powders that require mixing. The count per bottle (60 vs 120 vs 180 chews) also dictates how long one bottle lasts, which matters for a solution that often requires two to four weeks of consistent dosing to fully break the habit.

In‑Depth Reviews
1. YoYoBay No Poo Chews
This is the most generous bottle on the list, packing 180 soft chews in a single container — a full three-month supply for a medium-sized dog. The formulation goes beyond simple taste aversion by including a robust 6 Billion CFU probiotic blend alongside digestive enzymes and fiber sources like pumpkin and inulin. The goal here is not just to make stool less appealing today, but to build a healthier gut environment that naturally reduces the scavenging impulse over time.
The duck and pear flavor profile is unusual but effective; multiple reviewers noted their dogs actively looked forward to these soft nuggets. The inclusion of yucca schidigera works to deodorize the stool at its source, and calming herbs help soothe any underlying digestive discomfort that may trigger the behavior. With 180 chews in the bag and a strong probiotic backbone, this option favors owners who want a set-and-forget solution that addresses the root cause rather than just the symptom.
Some users reported that it took two to three weeks of consistent use before they saw a full behavioral shift, which aligns with how enzyme-based corrections work — the dog needs repeated negative reinforcement (unappealing stool) to unlearn the habit. A small number of dogs with extremely stubborn coprophagia still required additional management, but the overall success rate among reviewers was notably high.
Why it’s great
- Highest chew count (180) for longest supply
- 6 Billion CFU probiotics address gut health directly
- Duck & pear flavor is highly palatable
Good to know
- Requires 2-3 weeks of consistent dosing
- Not a magic bullet for every severely ingrained habit
2. Pet MD Stool Eating Deterrent
Pet MD takes a straightforward, veterinarian-formulated approach to coprophagia. These chewable tablets work through a taste-aversion mechanism: the blend of herbs, enzymes, and FOS prebiotic makes the dog’s own stool smell and taste unappealing after a few days of consistent dosing. The formula includes parsley and chamomile for breath freshening, which is a nice bonus for owners who cringe at doggy kisses from a poop-eating pup.
The chewable form is easy to administer, and most owners reported their dogs accepted the chamomile-flavored tablets without fuss. The dosage instructions are clear, and the product is designed for dogs over 12 weeks old. Several verified buyers with Great Danes and larger breeds noted visible improvements within the first week, with full habit cessation happening around the two-week mark.
Reviewers noted that the tablets were less effective for dogs that were eating other animals’ stool rather than their own, as the taste-aversion works best when the supplement is directly affecting the stool the dog is consuming. A small subset of users with extremely stubborn puppies found they still needed to combine the chews with environmental management, like prompt clean-up.
Why it’s great
- Veterinarian-formulated with a clean ingredient list
- FOS prebiotic supports immune function while deterring
- Quick results seen by many users within 7-14 days
Good to know
- 60-count bottle may require repurchasing for large breeds
- Less effective for dogs eating other animals’ stool
3. Pawsential No Poo Chews (Chicken)
Pawsential’s chicken-flavored soft chews are built around the concept of making stool less appealing through a proprietary enzyme blend. The 120-count bottle makes it a solid mid-range option, especially for multi-dog households where the per-dog cost becomes more attractive. These chews are formulated without GMOs, artificial preservatives, or synthetic fillers, which is a strong plus for owners who keep a clean diet for their pets.
The chicken flavor is a universal hit among dogs, making administration nearly effortless. Each 2-gram bite is sized appropriately for small, medium, and large breeds, so you don’t have to break tablets in half or adjust powder scoops. The product also claims breath-aid benefits thanks to natural herbs, which helps mitigate the odor that often comes with digestive imbalance.
While many users reported success, a notable minority found no effect at all, and some dogs experienced increased flatulence without any change in the stool-eating behavior. This suggests the formula may work best for dogs whose coprophagia is linked to incomplete digestion rather than pure habit or foraging instinct.
Why it’s great
- No GMOs, fillers, or synthetic additives
- Soft chews sized for all breeds, easy to give
- 120-count offers good value for multiple dogs
Good to know
- Inconsistent results reported by some users
- Can cause gas without stopping the behavior in sensitive dogs
4. Pawsential No Poo Chews (Beef Liver)
This is the same Pawsential base formula as the chicken-flavored version, but switched to a beef liver flavor that is often more appealing to picky eaters and small-breed dogs. The soft chew texture is consistent, and the 120-count bottle provides a full month of dosing for a small or medium dog, with enough leftover to confirm the habit is broken before deciding whether to reorder.
The key advantage here is the superior palatability of the beef liver flavor. Dogs that turned up their noses at chicken or chamomile-flavored tablets typically accepted these without hesitation. The veterinarian-formulated blend of probiotics and digestive enzymes targets the same core issue: improving digestion to make the stool less attractive. Several users with 10- to 20-pound breeds reported firmer stools and a noticeable drop in the scavenging behavior within two weeks.
As with the chicken variant, results were not universal. Some owners of particularly stubborn breeds or dogs with deeply ingrained coprophagia saw no improvement. The manufacturer’s dosing guidance also comes with a scoop that may be too large for very small dogs (under 15 lbs), requiring owners to halve or quarter the portions manually.
Why it’s great
- Beef liver flavor is highly palatable for picky eaters
- Soft chews are easy to portion for small breeds
- Same effective enzyme-probiotic base as chicken version
Good to know
- Included scoop is too large for toy breeds
- Effectiveness varies with stubborn coprophagia cases
5. NaturVet Coprophagia Stool Eating Deterrent
NaturVet is one of the most established names in the pet supplement space, and their Coprophagia tablet has been a go-to for years. The formula relies on a proprietary blend of yucca, parsley, chamomile, and enzymes designed to deodorize the stool and make it unpalatable. The wheat-free, chewable tablet format is easy to break in half for smaller dogs, and the 60-count bottle serves as an affordable entry point for owners new to this category.
The most compelling success stories come from owners who saw results within 48 to 72 hours of the first dose. A rescue shepherd owner reported a full stop in stool eating after just two days on the recommended dosage. The breath-aid claim is also legitimate — the parsley and chamomile combination does noticeably freshen your dog’s breath, which is a welcome side effect for any owner dealing with this messy habit.
On the downside, the tablet form is less palatable than soft chews, and some dogs refused to eat them outright, requiring owners to hide the pill in cheese or peanut butter. A significant number of negative reviews indicated that the product caused diarrhea or flatulence in sensitive dogs, and several users with German Shepherds and Beagles reported zero behavioral change even after finishing the entire bottle.
Why it’s great
- Fast results reported by many users within 2-3 days
- Breath-aid effect from parsley and chamomile
- Budget-friendly cost for a first-time trial
Good to know
- Tablet form is less palatable than soft chews
- Can cause loose stools or gas in sensitive dogs
