Watching your dog eat feces — either their own or another animal’s — is frustrating, concerning, and understandably gross. This behavior, known as coprophagia, is often linked to digestive enzyme deficiencies, poor nutrient absorption, or simply a stubborn habit. Addressing the root cause through diet and targeted supplementation is the most effective path to stopping it for good.
I’m Mohammad Maruf — the founder and writer behind WellFizz. I’ve spent hundreds of hours analyzing veterinary nutritional guidelines, studying canine digestive biochemistry, and researching the real-world performance of stool-eating deterrent supplements so you can skip the trial and error.
Whether you are looking for a probiotic-packed soft chew, a vet-backed supplement powder, or a daily deterrent treat, this guide cuts through the marketing to reveal the best dog food for dogs that eat poop.
How To Choose The Best Dog Food for Dogs That Eat Poop
Not all stool-eating deterrents are created equal. The most effective products tackle the behavior from the inside out — by changing the taste of the stool itself or by fixing the digestive deficiency that drives the craving. Here is what matters most.
Digestive Enzymes and Probiotics
Many dogs eat feces because their digestive system is not fully breaking down food, leaving undigested nutrients in the stool. A supplement rich in probiotics (beneficial bacteria) and digestive enzymes (amylase, lipase, cellulase) helps improve nutrient absorption and reduces stool appeal. Products with at least 1 billion CFU of probiotics per serving offer meaningful gut support.
Capsicum Extract and Taste Deterrents
For dogs that eat stool despite proper digestion, changing the taste of the feces itself is the most direct approach. Capsicum extract (chili pepper derivative) in controlled-release form like Capsimax makes the stool taste unpleasant without causing stomach upset. Look for this ingredient listed explicitly in the active ingredients.
Consistency and Multi-Dog Households
Coprophagia deterrents require daily, consistent use — usually for 7–30 days before results appear. In homes with multiple dogs, treating every dog is essential, because an untreated dog’s stool remains appealing to the treated dog. Products that work in under two weeks are the most practical for real-world use.

In‑Depth Reviews
1. Zesty Paws Chew No Poo Bites (Bison)
This bison-flavored formula is the most sophisticated deterrent on the market, combining a clinically studied Bacillus subtilis probiotic (DE111) with Capsimax — a controlled-release capsicum extract that makes feces taste unpleasant for hours. Owners of stubborn stool eaters report visible behavioral change within the first week, with many noting their dog starts sniffing then walking away instead of consuming.
The ancient grain base and corn-free allergen profile make this suitable for dogs with sensitive digestion. Each soft chew also includes a proprietary periodontal blend with parsley and peppermint, which helps manage the foul breath that often accompanies coprophagia. The 90-count supply covers one dog for a full month at the standard serving.
Some users found inconsistent results when only one dog in a multi-pet home was treated, reinforcing that all household dogs must take the chew for the deterrent to work fully. A minority of owners saw no change after 60 days, though the brand offers a satisfaction guarantee for those cases.
Why it’s great
- Dual-action: DE111 probiotic rebuilds gut flora while Capsimax taste-deters stool eating
- Corn-free formula with ancient grain base supports sensitive digestion
- Includes oral care blend for fresher breath alongside behavioral correction
Good to know
- Requires consistent daily use for 7–10 days before results become visible
- Less effective if not all dogs in the household are treated simultaneously
2. PRN Pharmacal CoproBan Anti-Coprophagia Soft Chews
CoproBan is one of the oldest and most veterinarian-recommended solutions for coprophagia, having been on the market since 1978. Its mechanism is straightforward — MSG and cellulose make the texture and taste of stool unpleasant to the dog. Many owners report an immediate 80–90 percent reduction in stool-eating behavior after starting this supplement, especially in young dogs still developing the habit.
The roast beef flavor is palatable to most dogs, and the soft chew format works for both dogs and cats — an important distinction if your dog is raiding the litter box. The dosing is weight-based: one chew per meal for dogs under 40 lbs, and an additional chew for every extra 40 lbs of body weight.
Quality control has been flagged by some buyers, with occasional reports of the chews arriving rock-hard in certain batches rather than soft. The chew is less effective in multi-pet homes unless every animal is dosed, and some owners found the single-dose approach insufficient for extreme cases of coprophagia.
Why it’s great
- Decades-proven MSG-based formula with strong reduction in stool eating
- Works for both dogs and cats — ideal for litter box raiding issues
- Vet-recommended and widely available at a reasonable per-dose cost
Good to know
- Inconsistent chew texture between batches reported by some users
- Full effectiveness requires dosing every dog in a multi-pet household
3. Zesty Paws Chew No Poo Bites (Chicken)
The chicken-flavored version of Zesty Paws’ stool deterrent formula packs 1 billion CFU of probiotics and seven different digestive enzymes into each soft chew. This product is designed for multi-dog homes where all dogs need to be treated to make the stool unappealing across the board. The “Too Cool For Stool” formula focuses on improving gut health to reduce the underlying drive to eat feces.
The oral care blend of parsley, apple cider vinegar, Ceylon cinnamon, and peppermint helps manage the foul breath that often accompanies stool-eating behavior, making post-chew cuddle time more pleasant. Many owners found the chicken flavor more palatable to picky eaters compared to other protein bases, and the soft texture allows for easy crumbling over dry food.
Results are gradual and not immediate — some dogs take up to two weeks before their feces becomes unappealing. A subset of owners with small puppies noted the chew size caused vomiting, suggesting it may need to be broken into smaller pieces for toy breeds. Success depends heavily on addressing the underlying cause of the behavior rather than relying solely on the supplement.
Why it’s great
- High probiotic and enzyme count supports comprehensive digestive health
- Chicken flavor is well-accepted by picky eaters and soft enough to crumble
- Multi-enzyme approach targets root cause rather than just masking the behavior
Good to know
- Results can take 7–14 days of consistent daily use
- Chew size may be too large for very small puppies or toy breeds
4. PawBliss No Poo Chews for Dogs
PawBliss approaches coprophagia as a digestive reset, packing each bacon-flavored soft chew with 1 billion CFU of probiotics from five bacterial strains plus six digestive enzymes including amylase, lipase, and cellulase. The addition of capsicum extract serves as a natural taste deterrent by making the stool unpalatable, while pumpkin and papaya soothe the digestive tract and help produce firmer, less odorous stools.
The formula goes beyond stool eating by including parsley, peppermint, and apple cider vinegar for fresh breath and gum health — a thoughtful addition for owners dealing with the breath consequences of the habit. The 120-count supply provides exceptional value, covering two months of daily use for a single dog or one month for two dogs in a household.
A small percentage of dogs experienced diarrhea during the adjustment period as their gut flora shifted. The chicken flavor listed in specifications conflicts with the bacon flavor in the marketing copy, which may confuse buyers comparing options. Results were inconsistent for some dogs, with no noticeable change after finishing the entire package for certain users.
Why it’s great
- Comprehensive formula with 5 probiotic strains and 6 digestive enzymes
- High 120-count value with capsicum extract for natural taste deterrence
- Includes breath-freshening ingredients to manage odor from the habit
Good to know
- Some dogs experience diarrhea during the initial gut adjustment phase
- Flavor labeling discrepancy between chicken (specs) and bacon (marketing)
5. Vet Classics Stop Stool Eating Pet Health Supplement
Vet Classics has been manufacturing pet supplements since 1994, and their Stop Stool Eating formula relies on a straightforward approach: glutamic acid changes the taste of the stool itself, while enzymes and probiotics support digestive health to address the underlying craving. The 90-count bottle at this price point makes it one of the most budget-friendly options for owners who want a vet-formulated product without the premium price tag.
The soft chews are palatable enough that most dogs eat them willingly, eliminating the need for hiding in food or force-feeding. Many owners report seeing results immediately — their dog begins sniffing then walking away from feces within a day or two of starting the supplement. The formula also helps reduce excess gas and urine odor, which adds a secondary benefit for households with multiple pets.
Effectiveness tends to drop off if the supplement is discontinued, meaning this is a long-term commitment rather than a permanent fix. A subset of dogs showed no response even after one month of daily use, and the manufacturer acknowledges that not every dog responds to the formula. The tablet form may be less convenient for owners accustomed to softer, treat-like chews.
Why it’s great
- Vet-formulated with glutamic acid for direct stool taste alteration
- Unbeatable per-chew value for long-term daily use
- Dogs eat willingly as a treat — no force-feeding or powder mixing required
Good to know
- Requires continuous use — behavior often returns when supplement is stopped
- Does not work for every dog; individual results vary significantly
6. Happy Paws No Poo Chews
Happy Paws differentiates itself with a fully vegan, organic, non-GMO formula that uses pumpkin, bromelain probiotics, and plant-based enzymes to support digestive balance and stool quality. This is the cleanest ingredient profile among the products reviewed, appealing to owners who prioritize plant-based supplementation for ethical or allergen reasons. The beef flavor is derived from natural sources and is well-accepted by most dogs.
The formula is designed for gradual, consistent use — the manufacturer recommends a 30-day minimum to see results, with many dogs adjusting within the first 7–10 days as digestive support builds. Owners who persisted through the adjustment period often reported that their dog stopped eating feces entirely, with some noting the treats themselves were so palatable that their dog looked forward to them as a daily reward.
Results were inconsistent across multi-dog households, with the supplement working well for one dog but not another within the same home. A significant concern reported by some users was diarrhea in their dogs during the first week of use, which required dosage adjustment or discontinuation. The 100-count supply at this price falls into the mid-range, but the smaller per-chew value compared to bulk options may be a consideration for long-term use.
Why it’s great
- Fully vegan, organic, non-GMO formula with cleanest ingredient profile
- Pumpkin and bromelain support gentle digestive adjustment
- Highly palatable beef flavor that dogs actively enjoy as a daily treat
Good to know
- Requires 30-day minimum commitment for best results
- Some dogs experience diarrhea during the first week of use
7. Purina Pro Plan FortiFlora Dog Probiotic Supplement
FortiFlora is the probiotic supplement most frequently recommended by veterinarians for digestive health, according to a 2020 Kantar Veterinary Tracker. While it is not a dedicated stool-eating deterrent, its mechanism directly addresses one of the root causes of coprophagia — poor digestion and nutrient malabsorption. Each 1-gram sachet delivers 1×10^8 CFU of Enterococcus faecium SF68, a probiotic strain proven to promote intestinal health and balance.
The powder format is easy to sprinkle over any food, and the liver flavor makes it highly palatable even for picky dogs. Owners of dogs with sensitive stomachs and intermittent loose stools frequently report dramatic improvements in stool firmness and overall gut health within just a few days. These firmer, better-digested stools are naturally less appealing for a dog to consume, which helps reduce coprophagia behavior indirectly.
FortiFlora is not a direct deterrent — it will not make the stool taste unpleasant through ingredients like glutamic acid or capsicum. Dogs that eat feces for behavioral or habit-driven reasons, rather than digestive deficiency, may not respond to this product alone. The 30-sachet box provides only one month of daily use, and owners with large dogs may need to double the dose for effective probiotic support, increasing the ongoing cost.
Why it’s great
- Vet-recommended probiotic strain with proven digestive health benefits
- Easy powder format that mixes seamlessly with any food
- Addresses root cause by improving stool quality and nutrient absorption
Good to know
- Not a direct stool taste deterrent — may not work for habit-driven coprophagia
- 30-count supply is less economical for ongoing daily use in larger dogs
