Our Picks at a Glance
How To Choose The Best Deterrent for Dogs Eating Poop
Not every dog eats poop for the same reason. Some are missing nutrients, some have an upset digestive system, and some simply picked up a habit that’s hard to break. Some chews use taste-aversion ingredients like yucca to make stool unappealing, while others add probiotics and enzymes to address digestive root causes. Start by identifying whether your dog’s habit stems from taste preference or digestive issues.
Look at the active ingredients first
The most effective formulas rely on ingredients like yucca schidigera, chamomile, and parsley. Yucca works by making the stool taste bitter and unappealing, while parsley and chamomile freshen breath and support calm digestion. Probiotics and digestive enzymes are the other half of the equation, helping your dog absorb nutrients properly so the urge to scavenge fades. Check the ingredient list to see if a chew addresses both the behavior and the digestion.
Match the dose to your dog’s weight
Most chews come with clear dosing based on your dog’s weight, like one chew for dogs under 40 pounds and two for larger pups. Giving less than the recommended dose can slow results, while overfeeding can upset a sensitive stomach. Follow the serving instructions on the label rather than guessing, and give the chew with a meal so it becomes part of the daily routine.
Factor in how long it takes to work
Some chews show results within a week, while others ask for two to four weeks of consistent use. A formula that works overnight is rare, so patience matters. If your dog has eaten poop for months, the habit may need several weeks of daily chews before you see a real change. Skim the product descriptions to understand the expected timeline before you commit.

In‑Depth Reviews
1. BARK&SPARK No Poo Chews
Our pick — over 4★ from 5,000+ verified ratings; the strongest balance of quality and price.
The crowd favorite that pairs habit-breaking chews with digestion support in one tasty chicken bite.
This pick leads the list because it tackles both sides of the poop-eating problem at once. Each chew combines probiotics and digestive enzymes to support gut health, which helps your dog absorb nutrients better and reduces the urge to scavenge. The vet-formulated blend uses natural premium ingredients, so the stool becomes less appealing while your dog’s digestion gets a steady boost.
The 120-count jar gives you a solid four-month supply for most dogs, and the chicken flavor has owners reporting that their dogs take it without hesitation. Buyers report that the chews are stress-free to give daily, and several mention that their dog’s skin and coat looked better after a few weeks of consistent use. The generous 90-day guarantee means you can try it without risk.
What wins people over is the balance of effectiveness and palatability. Dogs actually want to eat these, which removes the daily battle of prying open a pill bottle or hiding a tablet in food. Unlike the Pet MD drops that some dogs reject, the BARK&SPARK chews feel like a treat rather than a medicine.
What owners love
- Dogs love the chicken flavor and eat the chews willingly
- Probiotics and enzymes support healthy digestion and nutrient absorption
- Backed by a 90-day no-questions-asked guarantee
What to watch
- Some owners mention the chew often goes out of stock on subscribe and save
- A few picky dogs lose interest after the first week
Reach for this if: you want a vet-formulated, great-tasting chew that supports digestion while curbing the habit.
Look elsewhere if: your dog refuses treats with a strong flavor or you need a formula without chicken.
2. Pawsential No Poo Chews
A beef liver chew that works so well customers note firmer stools and better joint mobility in senior dogs.
This formula skips the gimmicks and goes straight to a potent mix of active ingredients. The probiotic blend works alongside a proprietary enzyme blend, while parsley leaf, chamomile, and yucca schidigera handle the taste-aversion side of the equation. The yucca makes the stool taste bitter, and the chamomile supports a calm, healthy digestive tract.
The beef liver flavor is the standout feature here, making this an easy daily add for even the pickiest eaters. Reviewers point out their Chug has much firmer bowel movements while on these chews, and the results hold up day after day. The 120-count supply means you won’t be reordering every few weeks, and the formula works for all dog breed sizes.
Note that some owners pair this with joint supplements and see combined mobility benefits, though the product itself is marketed strictly as a stool-eating deterrent. Shoppers say that it has been helping their dog and working very well for both digestion and the coprophagia habit.
What stands out
- Beef liver flavor that dogs genuinely enjoy
- Yucca schidigera provides natural taste aversion
- Supports firmer bowel movements with consistent use
Keep in mind
- Results can vary if your dog’s coprophagia stems from behavior rather than digestion
- Requires daily feeding to maintain the effect
Perfect for: dogs that turn their nose up at chicken flavors and need a liver-based chew they will actually eat.
Not ideal for: owners who want a quick fix and aren’t prepared to give the chew daily for several weeks.
3. Pet MD Stool Eating Deterrent
A budget-friendly chamomile chew that freshens breath while working to make droppings taste unappetizing.
This 60-count option uses taste-aversion chews to make droppings smell unappetizing to your dog, whether it’s their own stool or another dog’s. The formula pairs parsley and chamomile to freshen breath while digestive enzymes and a FOS prebiotic support gut health and immune function. It’s designed for all breeds over 12 weeks old, making it a flexible entry-level choice.
The price point makes this an easy first try if you’re not sure whether a chew will work for your dog. The chamomile flavor gets mixed reactions, though some buyers report their dogs genuinely like it and take it without fuss. If you have a puppy, the manufacturer suggests allowing two to four weeks for the droppings to become unappealing to your pup.
Effectiveness varies: some dogs stop within days, others see no change. While some owners mention it worked within days for a Great Dane puppy, others found it ineffective after two weeks with a poop-eating beagle. The smaller 60-count bottle also means you’ll need to reorder sooner than with the 120-count competitors, so factor that into your monthly routine.
Why it’s a value pick
- Entry-level price makes it easy to test effectiveness
- Parsley and chamomile help freshen breath
- Digestive enzymes and FOS prebiotic support gut health
The trade-off
- Effectiveness varies significantly between dogs
- 60-count supply runs out faster than 120-count jars
Best for: pet parents on a budget who want to test whether a chew-based deterrent works for their dog.
Think twice if: you have a large dog that needs a higher daily dose, as the supply will run out quickly.
4. Good Growlies Chew No Poo
An allergen-conscious chicken chew that pairs probiotics and enzymes to break the poop habit gently.
This formula takes a gentle approach, free of sugar, dairy, corn, and soy-derived products, which makes it a strong option for dogs with food sensitivities. The chicken flavor keeps it palatable, and the soft chew format means no struggling with pills or tablets. Customers note their Yorkies and rescue dogs take it happily as a daily treat.
The manufacturer promises a four-month supply from the 120-soft-chew jar, which works out to excellent value if your dog stays on the recommended one-a-day dose. The probiotics firm things up while the parsley and chamomile freshen breath, and the formula is suitable for both puppies and senior dogs of all breeds. At 11.68 ounces, this jar is noticeably heavier than the BARK&SPARK option at 8 ounces, giving you more product per jar.
The catch is that a few reviewers point out the chews are hard as rocks, which can be a problem for older dogs with dental issues. There’s also a small minority that saw digestive upset, though most dogs handle it without issues. If you have a sensitive-stomach dog, introduce the chew slowly and watch for changes.
What makes it premium
- Free of sugar, dairy, corn, and soy-derived ingredients
- Soft chew format is easy to give daily
- 120-count jar provides a four-month supply
Consider this
- An occasional unit arrives with very hard chews
- A small number of dogs experienced digestive upset
Choose this if: your dog has food allergies and you want an allergen-conscious formula from a US-based brand.
skip it if: your dog has dental issues that make hard chews difficult to manage.
5. TTIXRL 200 Chews No Poo
The biggest jar on the list at 200 chews, with owners reporting the habit stopped within a week.
If you’re tired of reordering every few weeks, this 200-count jar stretches further than any other pick on this list. The formula tackles the problem from the root by regulating the digestive system and supplementing multiple nutrients, which changes the smell of the poop and gradually reduces the urge. Bromelain, pumpkin, and glutamic acid make up the natural ingredient base.
The results are surprisingly fast for many owners. Shoppers say that a German Shepherd and Yorkie stopped eating cat and rabbit poo within a week, and another owner saw their dog’s own-poop habit stop completely. The chicken flavor is a hit with most dogs, though a few owners needed to hide the chews in peanut butter to get past an initial hesitation.
This is also a great option if you’ve tried sprays and training without success. One owner notes the chews worked after other methods failed, which speaks to the digestive-first approach. Just be aware that this brand has a smaller review base, so long-term reliability is less proven than the top picks.
Why it’s a value standout
- 200-count jar means fewer reorders and better cost per chew
- Natural ingredients including bromelain and pumpkin
- Free of GMOs, artificial preservatives, and colors
Know before you buy
- Smaller review base makes long-term reliability less certain
- A few dogs dislike the taste and need a disguise
Grab this if: you want maximum supply per purchase and your dog responds well to digestive-focused formulas.
Pass if: you prefer a more established brand with a larger owner base behind it.
6. STRELLALAB No Poo Chews
A poultry liver chew with a mild formula that owners say stops the habit completely if given daily.
This formula leans on digestive enzymes, yucca, and chamomile to support intestinal microbiota, which means steady digestive support for sensitive stomachs. The yucca gives the stool an unpleasant taste, while the chamomile and parsley blend freshens breath for better kisses. The natural chicken and liver flavoring makes it a soft chew most dogs take willingly.
The manufacturer suggests using the chews regularly to reduce coprophagia behavior in two to four weeks, and buyers report the soft texture is easy to serve next to a meal. One owner notes their 7.5-month-old puppy reduced poop eating from 50 percent to about 90 percent over several months, showing the formula works as a steady aid rather than an instant fix. Daily feeding is essential; skipping doses can bring the habit back.
Effectiveness is mixed: some dogs stop completely, others show no change. While many owners see complete results, a notable group reports the chews don’t deter the behavior at all. Some also mention a possible stronger urine smell and a slight increase in flatulence, which is a trade-off worth knowing. The mild formula is gentle on digestion, but it’s not the most potent option on this list.
What owners praise
- Soft texture that’s easy for picky and senior dogs to eat
- Digestive enzymes and yucca support sensitive stomachs
- Natural breath-freshening blend of parsley and chamomile
The honest catch
- Effectiveness is split, with some dogs showing no change
- Must be given daily or the habit returns
Best suited for: owners willing to stay consistent with daily feeding and who want a gentle, stomach-friendly formula.
Look elsewhere if: you need a deterrent that works fast and don’t want to risk mixed results.
7. LEGITPET Probiotics for Dogs
A probiotic powerhouse with 3 billion CFUs that owners say stops poop eating and itchy paws in days.
This isn’t just a stool-eating deterrent; it’s a full gut-health supplement that happens to solve the poop problem as a side effect. The 120 soft chews pack 3 billion CFUs per chew, using a premium probiotic lineup that includes Lactobacillus Fermentum, Brevis, Acidohilus, Plantarum, and Lactococcus Lactis. The powerful mix helps reduce gas, bloating, constipation, and diarrhea.
Owners mention impressive improvements across the board, with one noting itchy red paws resolved in five days, softer fur in three, and litter cravings stopped in seven. Another owner reports their dogs stopped eating poop within days, and the habit stayed gone through three weeks of daily use. The chew also works as an anti-itch supplement, making it a versatile addition to any dog’s routine.
Where this differs from the BARK&SPARK and Pawsential picks is its dual purpose. If your dog eats poop because of an imbalanced gut rather than a behavioral habit, the high CFU count addresses the root cause directly. The main holdback is that some picky dogs refuse the chew, though customer service is quick to offer a refund if your dog won’t take it. At 12.3 ounces, the jar is one of the heavier options on the list.
Why it’s a multi-tasker
- 3 billion CFUs per chew supports serious gut health
- Customers note itch relief and softer fur alongside poop-eating prevention
- Made in USA with sustainably sourced ingredients
Be aware
- Picky dogs may refuse the chew and need a disguise
- Success depends on underlying gut health issues
Pick this if: your dog also struggles with itching, paw licking, or digestive discomfort alongside the poop habit.
Skip if: your dog refuses new supplements and you want a simpler single-purpose chew.
8. Zesty Paws Chew No Poo
A premium bison-flavored chew that uses clinically studied DE111 bacteria and chili extract for a double-pronged approach.
Zesty Paws brings a science-forward angle to the poop-eating problem. The formula features DE111, a clinically studied Bacillus subtilis bacteria that supports gut health and immune function, plus Capsimax, a controlled-release form of Capsicum Extract that makes feces taste unpleasant. The ancient grain base adds a wholesome foundation that supports gut, periodontal, and immune health together.
Reviewers point out the 90-count jar of bison-flavored chews is a hit with dogs, with a 60-pound husky/pitt mix stopping coprophagia in about a week. The healthy teeth and gum proprietary blend adds oral care, and owners note firmer stools in dogs with sensitive stomachs. Digestive effects are a common point of praise, with the probiotics helping dogs feel balanced beyond just the poop habit.
This is the best choice if you want a brand with a strong reputation and a formula backed by clinically studied ingredients. The trade-off is the higher price point and the 90-count supply, which runs out faster than the 120-count jars. Effectiveness is also mixed for some dogs, so it’s not a guaranteed cure, but the digestive support makes it a worthwhile experiment for many owners.
What makes it premium
- Clinically studied DE111 bacteria supports gut health
- Capsimax chili extract adds taste aversion
- Supports periodontal health with a teeth and gum blend
Consider this
- Higher cost per chew than the 120-count competitors
- Effectiveness can be mixed for some dogs
Best for: owners who want a clinically studied formula from a trusted brand and don’t mind paying more per chew.
Pass if: you need a budget-friendly option or want a larger supply per jar.
9. PRN Pharmacal CoproBan
A veterinary-recommended roast beef chew with a since-1978 pedigree that also works for cats raiding the litter box.
This is the only pick on the list with a four-decade history behind it, and it’s the one most likely to be recommended by your vet. The roast beef flavored soft chew uses MSG and cellulose to make the stool taste and texture unpleasant, targeting the behavior directly. It’s safe for both dogs and cats, which makes it a unique solution if your dog raids the cat-litter box.
Shoppers say this reduces stool eating by about 90 percent when combined with training, and the benefit persists even two weeks after stopping. The pack of three gives you 120 total chews across three jars, though the per-pack 40-count format means more packaging to manage. The roast beef flavor is a hit with most dogs, and it’s easy to give with each meal.
The honest catch is that quality control has been inconsistent, with some owners receiving very hard, rock-like chews in the second box. Effectiveness is also mixed, with some dogs showing no change at all. It’s also the most expensive option on this list, so it makes sense for owners who want a vet-backed solution and can tolerate the premium cost.
Why vet-recommended
- Veterinary-recommended formula with a history since 1978
- Safe for both dogs and cats
- Benefit persists for weeks after stopping
Know the risks
- Quality control varies between boxes
- Effectiveness is mixed for some dogs
Reach for this if: your vet recommends it or you need a chew that also works for a cat-raiding dog.
Look elsewhere if: your budget is tight or you want a more reliable chew texture every time.
Understanding the Specs
Probiotics and Digestive Enzymes
These are the digestive support ingredients that address the root cause of many poop-eating habits. Probiotics are beneficial bacteria that help balance your dog’s gut flora, while digestive enzymes help break down food so your dog absorbs more nutrients. When your dog’s digestion improves, the urge to scavenge for missing nutrients often fades on its own.
Taste-Aversion Ingredients
Ingredients like yucca schidigera and capsicum extract work by making the stool taste bitter or unpleasant. Yucca is a natural plant extract that changes the flavor of the droppings, while capsicum is a chili-derived compound that adds a noticeable kick. These don’t harm your dog; they simply make the poop less appealing so your dog loses interest.
