Few things are more frustrating than watching your dog sneak a bite of something they shouldn’t: their own stool. This behavior, known as coprophagia, is not just unpleasant for you—it can point to underlying digestive imbalances that need addressing at the source. A targeted supplement can help break the cycle by making the stool taste unappealing while also supporting your dog’s gut health from the inside out.
I’m Mohammad Maruf — the founder and writer behind WellFizz. I’ve spent months analyzing the formulation science behind dog supplements, comparing the specific enzyme blends, probiotic strains, and ingredient sourcing across dozens of brands to identify which products actually deliver results for this tricky behavioral issue.
This guide breaks down the five most effective options currently available for deterrent for dogs eating poop, helping you pick the right formula based on your dog’s size, taste preferences, and specific digestive needs.
How To Choose The Best Deterrent For Dogs Eating Poop
Selecting a coprophagia deterrent isn’t about finding the cheapest bag of treats. The most effective products work by making the stool itself taste bad through digestive enzymes and probiotics that alter the gut environment. Here are the three most important factors to consider.
Enzyme and Probiotic Blend
The core mechanism of a quality deterrent is its ability to break down proteins and starches in the gut, leaving waste less appealing. Look for formulas that clearly list specific enzymes like bromelain (from pineapple) or papain (from papaya), alongside multiple probiotic strains such as Lactobacillus acidophilus or Bacillus subtilis. A single-strain product rarely achieves the same results as a multi-strain formula with at least 1 billion CFUs per serving.
Chew Count and Daily Serving
Consistency is everything with behavior-modifying supplements. A bottle of 30 chews that lasts only two weeks will not give you enough time to see meaningful behavioral change. Look for counts of 120 or higher to ensure at least a one-month trial period. Also check whether the serving size scales by weight: a small dog may only need half a chew per day, while a large breed may need two or more.
Natural Ingredient Profile
Avoid products loaded with artificial fillers, corn syrup, or chemical preservatives. The best deterrents use natural carriers like pumpkin powder, sweet potato, or wild yam—ingredients that double as prebiotics to feed the good bacteria. Beef liver or chicken flavoring helps with palatability, but ensure the active ingredients aren’t buried at the bottom of the label.

In‑Depth Reviews
1. No Poo Chews – Pawsential
Pawsential’s No Poo Chews hit the sweet spot between formulation quality and everyday practicality. Each chew combines probiotics and digestive enzymes in a beef liver base that most dogs accept eagerly—even picky eaters and seniors. The 120-count bottle provides a full month-plus supply for smaller dogs, giving you enough time to assess behavioral changes without constant reordering.
Customer feedback highlights noticeably firmer stool within the first week, along with reduced sulfur-like odor from the anal glands. The chew format eliminates the mess of powders or capsules, and the American-made, GMP-certified production adds a layer of trust. A small caveat: the included scoop is generous for toy breeds (under 10 pounds), so you’ll want to split the indicated serving to extend the bottle’s life.
For pet owners wanting a direct, no-fuss coprophagia deterrent that also supports digestion, this is the most balanced pick on the market. The formulation directly addresses the root cause—gut imbalance—rather than just masking stool odor with temporary additives.
Why it’s great
- Veterinarian-formulated enzyme and probiotic blend targets stool eating.
- Beef liver flavor makes daily dosing effortless for most dogs.
- 120-count bottle provides consistent, long-term use value.
Good to know
- Serving scoop is oversized for dogs under 10 pounds.
- Some reviews report it didn’t work for every dog—results vary by gut condition.
2. No Poo Chews – CHEWIA
CHEWIA’s No Poo Chews take a more ingredient-focused approach, featuring pumpkin powder and wild yam as natural prebiotic fibers that feed beneficial gut bacteria. The 180-count bottle is the highest volume among the dedicated deterrent-specific products here, meaning you pay less per chew while getting a longer runway to correct the behavior.
The formulation is notably clean—allergen-free and free of artificial additives—and the soft texture is suitable for both puppies and senior dogs with dental sensitivity. Early user reports indicate the chews help reduce stool-eating behavior by improving overall digestion and nutrient absorption rather than relying on a secondary bitter taste. A small number of reviewers also noted fresher breath as a welcome side benefit.
One consideration: these chews require refrigeration to maintain freshness, which is common with high-moisture soft chews. If you travel frequently with your dog, this may be less convenient than a shelf-stable alternative. Still, for owners looking for a premium, natural formula backed by real ingredients and a generous count, this is a strong contender.
Why it’s great
- 180-count provides the highest chew count for dedicated stool-deterrent formulas.
- Natural pumpkin and wild yam support digestive health and gut motility.
- Allergen-free and suitable for puppies and seniors.
Good to know
- Requires refrigeration after opening.
- Primarily a probiotic chew—works best with consistent daily use over several weeks.
3. LEGITPET Probiotics
LEGITPET distinguishes itself through raw probiotic potency: 3 billion CFUs per chew across five targeted strains (Lactobacillus fermentum, brevis, acidophilus, plantarum, and Lactococcus lactis). This high-density dose makes it particularly effective for dogs whose coprophagia stems from chronic digestive upset, seasonal allergies, or a weak immune system that disrupts normal gut flora.
The all-natural, USA-made formula is a favorite among owners of allergy-prone breeds like German Shepherds and English Bulldogs. Several long-term users report that the chews helped eliminate the need for expensive veterinary anti-itch medications while simultaneously curbing stool-eating behavior. The soft texture makes dosing simple, and the 120-count bottle provides a solid month of daily treatment for a medium-sized dog.
It’s worth knowing that while the probiotic potency is excellent, the primary marketing focus is on digestive and immune support rather than strictly as a coprophagia deterrent. If your dog’s stool-eating is severe and not linked to allergies or gut inflammation, a more dedicated deterrent formula might produce faster behavioral results. For owners wanting dual benefits—allergy relief plus stool-eating reduction—this is a clever choice.
Why it’s great
- 3 billion CFUs per chew—the highest probiotic potency in this comparison.
- Helps with seasonal allergies, itching, and immune support alongside stool eating.
- Made in the USA using sustainably sourced ingredients.
Good to know
- Not marketed exclusively as a stool-eating deterrent; best for dogs with broader gut issues.
- Some owners dislike the smell of the soft chews.
4. Vetnique Glandex Probiotic Chews
Vetnique Glandex Daily Probiotic Chews are a veterinarian-founded formulation that includes five clinically-studied probiotic strains plus bromelain—a digestive enzyme that helps break down proteins for better absorption. This makes the product particularly useful for dogs with sensitive stomachs that experience loose stools, gas, or bloating, which can trigger the urge to eat waste.
While Glandex is best known in the pet community for its anal gland support line, these probiotic chews are marketed primarily for gut and immune health. The dual prebiotic blend of sweet potato and FOS feeds the live cultures and helps firm up stool consistency. Owners of large breeds like English Mastiffs report a noticeable reduction in the frequency of explosive diarrhea and gas. The bacon flavor is widely accepted, though some dogs may be indifferent.
The main limitation here is the 30-count bottle size—far smaller than the other products on this list. For a large dog requiring multiple chews daily, this bottle may last only two weeks. It is better suited as a shorter-term reset for acute digestive episodes than as a long-term, daily deterrent regimen. If you need a large-volume product for ongoing stool-eating prevention, consider one of the higher-count options above.
Why it’s great
- Vet-formulated with 5 clinically-studied probiotic strains and bromelain enzyme.
- Excellent for dogs with loose stools, gas, or sensitive stomachs.
- Pairs well with Glandex Anal Gland Chews for scent-related issues.
Good to know
- Only 30 chews per bottle—runs out quickly for multi-dog or large-breed homes.
- Not specifically formulated as a coprophagia deterrent; results may be indirect.
5. TTLXRL Probiotics 200 Count
TTLXRL Probiotics deliver the highest tablet count in this roundup at 200 per bottle, making it the most economical option for owners on a tight budget or those managing multiple dogs. The formula includes Bacillus subtilis, dried pumpkin, and papaya to support a healthy gut environment and relieve occasional diarrhea, constipation, and flatulence.
Dog owners report that the chicken-flavored soft chew is highly palatable, and the half-chew serving size for smaller breeds means a single bottle can stretch to cover two months or more. The product has successfully resolved sensitive-stomach issues like night-time waking due to gas, and several reviewers noted improvements in skin itching as a secondary benefit. For owners whose primary concern is overall digestive health rather than aggressive stool-eating intervention, this is a sensible starting point.
The trade-off is formulation depth. Unlike the dedicated deterrent products from Pawsential or CHEWIA, this is primarily a general probiotic supplement—it may not contain the specific enzyme profile needed to make stool distinctly unappealing to a determined coprophagia dog. For mild cases, it may be enough; for persistent stool eaters, you may need to step up to a more targeted formula.
Why it’s great
- 200-count bottle offers the best cost-per-chew value in this list.
- Chicken flavor is widely accepted and easy to administer daily.
- Helps with gas, loose stool, and general digestive maintenance.
Good to know
- Not specifically designed as a coprophagia deterrent—mild results for stool eating.
- Low-potency probiotic strain list compared to targeted formulas.
