Few things test a pet parent’s resolve quite like watching your dog snack on their own stool. The frustration isn’t just the gross-out factor — it’s the worry that something is off with their nutrition or gut health. The habit, formally called coprophagia, often stems from digestive inefficiency or a simple nutrient imbalance that makes the stool smell or taste appealing to your dog.
I’m Mo Mahin — the founder and writer behind Furric. I’ve spent hundreds of hours studying pet supplement formulations, cross-referencing ingredient lists with veterinary data on enzyme activity, probiotic CFU counts, and stool-odor reduction mechanisms to find what actually breaks this behavior.
Below, I’ve assembled the most effective options on the market. After comparing enzyme profiles, palatability ratings, and real owner results, the following list represents the best supplement to stop dogs from eating poop that targets the root cause of the behavior rather than just masking the habit.
How To Choose The Best Supplement To Stop Dogs From Eating Poop
Not all poop-eating deterrents are created equal. Some rely on a single ingredient to make stool taste bitter, while others address the digestive imbalance that drives the behavior in the first place. Understanding what to look for on the label separates a short-term fix from a lasting solution.
Enzyme Profile and Probiotic Potency
The most effective formulas include a blend of digestive enzymes—amylase for carbohydrates, lipase for fats, and cellulase for plant fiber. These enzymes help your dog extract more nutrients from their food, leaving less undigested material in the stool that might smell appealing. Probiotic potency, measured in CFUs (colony-forming units), should be in the billions to meaningfully shift gut flora balance. A higher CFU count typically leads to faster odor reduction in the stool.
Key Deterrent Ingredients: Yucca and Capsicum
Yucca schidigera works by breaking down the compounds that cause fecal odor, making the stool less attractive to your dog. Capsicum extract takes a different approach — it creates a mildly irritating sensation when consumed, which discourages repeat attempts. Formulas that combine both tend to show results faster, often within the first week.
Palatability and Delivery Method
A supplement only works if your dog actually eats it. Soft chews are the most accepted format across breeds and ages, with bacon, chicken, and duck flavors leading in palatability scores. Harder chews may require soaking or crumbling for acceptance, especially in smaller dogs or those with dental sensitivities. The daily serving size also matters — a 120-count supply at one chew per day stretches further than a 60-count at two chews per day.

In‑Depth Reviews
1. NaturVet Scoopables Coprophagia for Dogs
The NaturVet Scoopables formula stands out for its 25-year manufacturing pedigree and veterinarian-grade approach to coprophagia. Each scoop contains 70 mg of active ingredients including yucca schidigera, chamomile, and a proprietary enzyme blend that works at the digestive level to reduce stool odor and appeal. The hickory smoked bacon flavor uses a flavor-packed delivery method that dogs find irresistible, eliminating the struggle of getting a finicky eater to take their supplement.
Owners report that results take time — typically two to four weeks before a noticeable reduction in stool-eating behavior. The enzyme blend maintains proper gut flora while the yucca works to neutralize the compounds that make stool smell attractive. Breath freshening is a secondary benefit that owners consistently note, with improvements visible as early as three weeks into use.
The 11-ounce bag provides a solid supply for single-dog households. Some users found they needed to pair it with pumpkin purée in the early weeks for dogs with persistent habits. The formula is safe for dogs over 12 weeks and can be given to multiple dogs in the same home if they all share a yard.
Why we love it
- Trusted brand with over two decades in the pet supplement space
- Comprehensive blend of yucca, chamomile, and digestive enzymes
- No stomach upset reported even in sensitive dogs
Good to know
- Results may take 2-4 weeks of consistent use
- Must give to all dogs in multi-dog households for full effectiveness
2. PawBliss No Poo Chews for Dogs
The PawBliss formula is built around a high-potency digestive reset approach, packing 1 billion CFU of probiotics per chew alongside six distinct digestive enzymes—amylase, lipase, and cellulase among them. This is one of the most aggressive enzyme profiles you will find in a coprophagia deterrent, targeting the core trigger of stool eating: incomplete digestion that leaves nutrient-rich material in the waste.
The inclusion of capsicum extract takes a dual-action approach by making the stool taste unappealing while the probiotics and enzymes work on the digestive side. Organic pumpkin and papaya soothe the digestive tract and support regular, less odorous stools. The bacon flavor is consistently rated as highly palatable by owners of picky eaters, with soft chew texture that requires no crumbling or soaking.
Additional ingredients like parsley, peppermint, and apple cider vinegar target bad breath from the source, addressing the secondary frustration of stool-breath that often follows the primary habit. The 120-count supply at one chew per day offers roughly four months of coverage for a single dog, making it a strong value proposition.
Why we love it
- Industry-leading 1 billion CFU probiotic potency
- Six-enzyme blend for comprehensive digestive support
- Capsicum extract adds an immediate taste deterrent layer
Good to know
- Results may vary in dogs with deeply ingrained habits
- Some buyers misattributed skin/ear benefits meant for a different formula
3. Chewia No Poo Chews for Dogs
The Chewia formula focuses on natural, allergen-free ingredient sourcing with a core blend of pumpkin, wild yam powder, digestive enzymes, and yeast powder. The duck flavor is a standout in a market dominated by bacon and chicken options, making it an excellent alternative for dogs with poultry sensitivities or those who reject standard flavors. The soft chew texture earns consistent praise for being easy to administer even to small breeds.
At 180 chews per jar, this is the highest-count supply in this lineup. For a single dog on a one-chew daily regimen, this stretches to six months of coverage — a significant convenience factor that reduces reorder frequency. The probiotics and enzyme blend are formulated to support gut health from the inside out, addressing the digestive root of coprophagia rather than just masking the behavior.
Owner feedback indicates that dogs treat these as regular treats, with no resistance to taking them daily. The natural ingredient profile — including Allergen-Free labeling — gives pet parents with sensitive dogs an option that won’t introduce new dietary triggers. Bad breath reduction is a reported secondary benefit, with the gut-health approach reducing oral odors at their digestive source.
Why we love it
- 180-count jar provides up to six months of daily use
- Unique duck flavor appeals to dogs with poultry sensitivities
- Allergen-free formula with natural pumpkin and wild yam
Good to know
- Results may vary as a standalone deterrent for strong habits
- Primarily designed as a probiotic supplement rather than aggressive deterrent
4. Vet Worthy Coprophagia Deterrent for Dogs
Vet Worthy takes a behavior-focused approach by combining yucca schidigera and parsley for stool odor reduction with chamomile for behavioral balance. The chamomile inclusion is distinctive — it helps calm the anxious or compulsive tendencies that often underlie coprophagia, particularly in dogs who eat stool due to stress or confinement. Glutamic acid and brewer’s yeast round out the formula to support digestive health and make stool taste undesirable.
Some owners report visible results in as little as three days, particularly in cases where the stool eating began after antibiotic use disrupted gut flora. The chews are soft and bacon-flavored, though a subset of users found them hard enough to require cutting into smaller pieces for small breeds. Soaking in water for a few minutes softens them sufficiently for dogs with dental sensitivity or smaller mouths.
The 60-count supply is best suited for single-dog households or as a trial period to gauge effectiveness before committing to a larger order. The NASC (National Animal Supplement Council) seal indicates third-party quality verification, and the made-in-USA manufacturing adds an extra layer of quality assurance. The formula includes canola and sunflower oil, which some owners prefer to note for dogs with specific oil sensitivities.
Why we love it
- Chamomile helps calm compulsive stool-eating behavior
- NASC seal and USA manufacturing for quality assurance
- Some owners report results within 3 days
Good to know
- 60-count supply is shorter duration than most competitors
- Chews can be hard; may require soaking for small dogs
5. Healthy Pup Stop Poop Eating for Dogs
The Healthy Pup formula relies on glutamic acid as its primary deterrent mechanism — an amino acid compound that makes stool taste bitter and disgusting to dogs. This chemical-taste approach is paired with yucca schidigera to neutralize stool odor, attacking the problem from both the taste and smell angles simultaneously. Chamomile, flaxseed, and a digestive enzyme blend support gut health and nutrient absorption on the backend.
Owner feedback reveals a split response based on dog size and digestive sensitivity. Larger dogs (40+ pounds) tolerate the formula well with no side effects, and many owners report months of clean behavior after starting the supplement. Smaller dogs and those with sensitive stomachs have experienced vomiting or illness in some cases, making this a formula that requires cautious introduction in toy breeds or dogs with known digestive fragility.
The 120-count supply is appropriately sized for multi-dog households, since effective coprophagia prevention requires giving the supplement to all dogs who share access to the same stool. The unflavored soft chews are accepted well by picky eaters who might reject bacon or chicken flavoring. The packaging has undergone an update, but the formula remains consistent with previous iterations.
Why we love it
- Glutamic acid provides a potent bittering agent for strong deterrence
- Dual approach targets both taste and smell of stool
- 120-count supply suits multi-dog households
Good to know
- May cause digestive upset in smaller or sensitive dogs
- Results are inconsistent across different breeds and body weights
