Why Do Dogs Eat Poop? The Disgusting Truth & How to Stop It Fast
Jump to
Welcome to the most disgusting, embarrassing, and surprisingly common dog behavior that nobody wants to talk about at dinner parties: poop eating.
If you've ever caught your dog in the act and immediately Googled "why do dogs eat poop" with a mixture of horror and desperation, you're not alone. This behavior—called coprophagia in the veterinary world—is shockingly normal. But that doesn't make it any less gross.
Here's what you need to know: your dog isn't broken, sick, or weird. But they might be trying to tell you something. And yes, there are ways to make it stop.
If you’ve been going down the same dog-behavior rabbit hole I do, there’s a lot more like this over on the GREET Dog blog.
of dogs are classified as "serious" poop eaters
That means they've been caught eating poop 5+ times. Even more dogs have done it at least once.
Key Takeaways
- Poop eating is common but not normal—16% of dogs do it regularly, but it usually signals an underlying issue
- It's rarely dangerous unless the poop contains parasites, toxins, or medications
- Different types of poop mean different things—eating their own vs. cat poop vs. other dogs' poop have different causes
- Puppies do it more than adult dogs—many grow out of it naturally
- It CAN be stopped with the right combination of diet changes, training, and environmental management
Understanding Why Dogs Eat Poop: It's Actually Complex
Let's start with the uncomfortable truth: from a dog's perspective, poop is not disgusting. They don't have the same "eww that's gross" response we do. To them, it's just... information and potential calories.
But here's where it gets interesting: not all poop-eating is created equal. The reason your dog eats their own poop is completely different from why they raid the litter box or snack on rabbit droppings at the park.
The Evolutionary Explanation (Why It's Hardwired)
Dogs evolved from wolves who were opportunistic scavengers. In the wild, when food was scarce, nothing went to waste—including feces. Herbivore poop (like rabbit or deer) was actually a decent source of partially digested plant matter and nutrients.
Mother dogs instinctively eat their puppies' poop to keep the den clean and hide the scent from predators. This behavior is completely normal in nursing mothers and isn't something you need to stop.
The problem? Some dogs never turn off this instinct, or they develop it for other reasons as they age.
Why Do Dogs Eat Their Own Poop? The 7 Real Reasons
When Luna ate her own poop that day, I thought she was just being gross. Turns out, she was actually showing signs of a nutritional deficiency from her cheap puppy food. Once I switched her to higher-quality food, the behavior stopped within a week.
Here are the real reasons dogs eat their own feces:
1. Nutritional Deficiencies or Poor Diet Quality
This is the big one. If your dog's food isn't nutritionally complete, or if they're not properly digesting and absorbing nutrients, their poop still smells like food to them.
Low-quality dog foods with lots of fillers (corn, wheat, soy) pass through the digestive system partially undigested. To your dog's nose, that poop is basically "food part 2."
Signs this might be the issue:
- You're feeding a budget or low-quality food brand
- Your dog is always hungry despite eating recommended portions
- Their poop is large in volume (sign of poor nutrient absorption)
- They're eating poop consistently, not just occasionally
The fix: Upgrade to a higher-quality dog food with better digestibility. Look for foods with named meat proteins as the first ingredient and minimal fillers. If I were starting there, this is one of the first places I’d look → Vital Essentials Dog Food
2. Hunger or Inadequate Feeding
Sometimes it's simpler than diet quality—your dog is just hungry.
This is common in:
- Puppies going through growth spurts
- Active or working dogs not getting enough calories
- Dogs on weight-loss diets that are too restrictive
- Dogs with parasites stealing nutrients (more on that below)
3. Digestive Disorders and Malabsorption Issues
If your dog has an underlying digestive problem—like exocrine pancreatic insufficiency (EPI), inflammatory bowel disease, or intestinal parasites—they're not absorbing nutrients properly. Their poop literally still has nutritional value because they didn't digest it the first time.
Red flags that it's medical:
- Sudden onset in an adult dog who never did this before
- Weight loss despite eating normally
- Diarrhea or soft stool consistently
- Increased appetite but no weight gain
- Greasy or foul-smelling poop
If you're seeing these signs, vet visit ASAP. EPI and similar conditions are serious but treatable. And if you want a simple place to start browsing digestive support and general health stuff, I’d check here → Nutramax healthy dog supplements
4. Parasites (The Hidden Culprit)
Intestinal parasites like roundworms, hookworms, and giardia steal nutrients from your dog's digestive system. This creates both hunger and nutrient-rich poop—a perfect storm for coprophagia.
The cruel irony? Eating poop can reinfect them with parasites, creating a vicious cycle.
If you’re seeing other weird health stuff too, I’d rather overreact than ignore it. This is another solid place to browse the basics while you’re figuring things out → Pet MD
5. Boredom and Lack of Mental Stimulation
A bored dog is a creative dog—and not in good ways. Poop eating can become a self-entertaining behavior for under-stimulated dogs, especially those left alone in yards for long periods.
It's like the dog equivalent of scrolling TikTok for hours. They're not doing it because it's nutritious—they're doing it because there's literally nothing else interesting happening.
Signs it's boredom:
- Happens most when you're not around or not paying attention
- Your dog has limited toys, walks, or mental enrichment
- Other destructive behaviors are present (digging, chewing furniture)
- They seem to do it for attention or reaction
This is usually where I start thinking less about “bad behavior” and more about boredom, routine, and enrichment. If that sounds familiar, these are the kinds of things I’d look at first → KONG Dog Toys and Outward Hound dog puzzles and toys
A lot of this overlaps with other weird dog behaviors too. I got into that side of things more here → Why Do Dogs Fall Asleep So Fast?
6. Attention-Seeking Behavior
Here's the messed up psychology: if you freak out every time your dog eats poop, you're actually rewarding the behavior with attention.
Dogs don't differentiate between positive and negative attention. To them, your horrified "OH MY GOD NO STOP THAT" is still engagement and interaction.
Some dogs figure this out fast and use poop-eating as a guaranteed way to get you to pay attention to them. It's manipulative genius, honestly.
7. Stress, Anxiety, or Punishment-Based History
This one breaks my heart. Dogs who were punished for accidents in the house sometimes eat their poop to "hide the evidence."
They learned: Poop in house = yelling and punishment. Solution? Eat the poop so there's no evidence.
This is most common in dogs who:
- Came from puppy mills or hoarding situations
- Were harshly punished during house training
- Have generalized anxiety or fear-based behaviors
- Are in high-stress environments
If your dog already leans anxious or attached, this usually connects to a bunch of other behaviors too. This one pairs well with it → Why Do Dogs Love You So Much?
Why Do Dogs Eat Cat Poop? (The Litter Box Delicacy)
Okay, here's where we need to address the elephant—or rather, the litter box—in the room. Cat poop is like caviar to dogs.
And I hate that I have to explain why: cats are obligate carnivores with high-protein diets. Their poop is basically concentrated protein. To a dog, it smells like a premium treat.
This is less about nutritional deficiency and more about opportunity and taste preference. It's gross, it's embarrassing, but it's also incredibly common.
of dogs will eat cat poop if given access
This is the most commonly consumed "other animal" poop. It's not a behavior problem—it's an access problem.
Why cat poop specifically?
- High protein content from cat's carnivorous diet
- Strong smell that's attractive to dogs
- Conveniently located in an accessible box (like a buffet)
- Cats bury it partially, which triggers dogs' scavenging instinct
The solution? Physical barriers. Put the litter box somewhere your dog can't reach—baby gates, elevated platforms, or covered boxes with cat-sized entrances. You can't train this away; you have to remove access.
Why Do Dogs Eat Other Dogs' Poop?
When dogs eat other dogs' poop (especially in dog parks or multi-dog households), it's usually one of these reasons:
1. Social Learning and Hierarchy - Submissive dogs sometimes eat dominant dogs' feces as an appeasement behavior. It's weird, but it's rooted in pack dynamics.
2. Information Gathering - Dogs learn a LOT from other dogs' poop—diet, health status, reproductive state. Eating it is extreme "research," but some dogs do it.
3. Cleaning Behavior - In multi-dog homes, one dog may take on the role of "cleaner" and eat other dogs' accidents. This is especially common if they witnessed a mother dog cleaning up after puppies.
4. Same Nutritional Reasons - If another dog is eating low-quality food, their poop still smells like food to your dog.
Why Do Dogs Eat Rabbit Poop (and Other Wild Animal Feces)?
Rabbit poop, deer droppings, goose poop—if it's from an herbivore, many dogs consider it a snack.
Why? Herbivore poop is partially digested plant matter and can contain nutrients, especially for dogs who are instinctive scavengers. It's evolutionary behavior—wild canines ate this stuff all the time.
Is it harmful? Usually not, but it can carry parasites (especially rabbit and deer poop). It's gross and can cause upset stomach, but it's rarely dangerous.
Can you stop it? Good luck. This is one of the hardest behaviors to train away because it's so instinctive. Best bet: keep your dog on leash in areas with lots of wildlife poop and redirect before they get to it.
Why Do Dogs Eat Their Own Vomit? (Yes, We're Going There)
Since we're already deep in the gross zone, let's address this: dogs eating their vomit is actually more normal than poop eating.
Mother dogs in the wild regurgitate partially digested food to feed their puppies. When a dog vomits and re-eats it, they're following the same instinct: "This is still food, just... pre-processed."
Unless they're vomiting constantly or showing signs of illness, re-eating vomit isn't usually a health concern. It's just another charming dog behavior that reminds us they're not humans in fur suits.
Is It Unhealthy for Dogs to Eat Their Own Poop?
The question everyone wants answered: is this actually dangerous?
The honest answer: Usually no, but sometimes yes.
When It's (Relatively) Harmless:
- Eating their own fresh poop - Gross but not particularly dangerous (they're re-ingesting their own bacteria)
- Herbivore poop (rabbit, deer) - Low risk, though parasites are possible
- Their own vomit - Usually fine unless vomiting is excessive
When It's Potentially Dangerous:
- Other dogs' poop - Can spread parasites, viruses (parvo), bacteria
- Cat poop - Can contain Toxoplasma and other parasites, plus litter ingestion risk
- Wild animal poop - Parasites, bacteria, potential toxins
- Poop from dogs on medication - Can ingest harmful drug residues
- Poop that's been outside for days - Bacterial overgrowth, mold, parasites
⚠️ Real Health Risks from Poop Eating:
- Parasites: Roundworms, hookworms, giardia, coccidia
- Bacterial infections: Salmonella, E. coli, Campylobacter
- Viral diseases: Parvovirus (especially in unvaccinated puppies)
- Intestinal blockage: From ingesting cat litter along with feces
- Toxins: If the other animal ate something poisonous
- Drug exposure: Medications passing through another dog's system
Bottom line: While eating their own fresh poop is low-risk, eating other animals' feces can absolutely make your dog sick. It needs to stop.
Coprophagia in Puppies: Why They Do It More
If you have a puppy who eats poop, there's actually some good news: they'll probably grow out of it.
Puppies are:
- Oral explorers - They investigate the world by putting things in their mouths (including poop)
- Imitating mom - They watched their mother clean up after them and think it's normal
- Developmentally curious - Everything is new and interesting, including bathroom habits
- Teething - Sometimes seeking different textures to chew
Most puppies stop this behavior naturally by 9-12 months old as they mature. But if you make a huge deal about it, you can accidentally reinforce it (attention-seeking behavior).
✅ How to Handle Puppy Poop-Eating:
- Don't freak out - Calm, neutral reaction only
- Clean up immediately - Remove temptation before they can get to it
- Supervise bathroom breaks - Redirect before it happens
- Reward elimination, then immediate recall - "Good potty! Come here!" with treat
- Feed high-quality puppy food - Reduces nutritional motivation
How to Stop Your Dog From Eating Poop: Methods That Actually Work
Alright, enough explaining WHY—let's talk about how to make it STOP.
I'm going to be real with you: there's no magic bullet. But there ARE proven strategies that work when combined properly.
Method 1: Immediate Cleanup (The Most Effective)
This is boring but true: the single most effective way to stop poop eating is to not let poop exist around your dog.
- Pick up poop immediately after your dog goes
- Supervise all bathroom breaks (yes, even in your fenced yard)
- Use a leash in the yard if necessary to control access
- Clean up other animals' poop from your property
Is it annoying? Yes. Does it work? 100%.
And if you’re constantly cleaning accidents or yard messes anyway, this is one of those brands that genuinely makes that part easier → Pooph Pet Cleaner
Method 2: Diet Upgrade
Switch to a high-quality, highly digestible dog food with:
- Named meat protein as first ingredient (chicken, beef, fish—not "meat meal")
- Minimal fillers (no corn, wheat, soy as primary ingredients)
- Added digestive enzymes or probiotics
- Appropriate calorie content for your dog's activity level
When food is properly digested and absorbed, poop is less "nutritionally interesting" to your dog.
Expect results in: 1-2 weeks of consistent feeding
If you’re still figuring out what direction to go, I’d start with a cleaner food option and see how your dog responds → Vital Essentials Dog Food
Method 3: Deterrent Products (Hit or Miss)
There are supplements you add to your dog's food that are supposed to make their poop taste terrible. Popular brands include For-Bid, Deter, and CoproBan.
Do they work? Sometimes. Results are inconsistent because:
- They only work on your dog's own poop, not other animals'
- Some dogs don't care about the taste change
- They require consistent daily use
- They don't address underlying causes
Worth trying as part of a multi-pronged approach, but don't rely on them alone.
Method 4: Pineapple or Pumpkin (The Home Remedy)
The internet swears by adding pineapple or meat tenderizer to dog food to make poop taste bad.
Does it work? Anecdotally, sometimes. Scientifically, there's no strong evidence. But it's safe to try (in moderation) and might help with some dogs.
How to try it:
- Add 2-3 chunks of fresh pineapple to meals daily
- Or add 1-2 tablespoons canned pumpkin (not pie filling)
- Use for 2 weeks to see if behavior changes
❌ MYTH: Hot sauce or pepper on poop will stop them
Please don't do this. It can cause mouth and stomach irritation, doesn't address the root cause, and many dogs will eat it anyway. Plus, it's treating a symptom, not solving the problem.
Method 5: Training "Leave It" Command
Teach a rock-solid "leave it" command:
- Start with treats in your hand
- Say "leave it" and reward when they back away
- Graduate to treats on the floor
- Eventually practice with poop (on leash for control)
- Reward heavily for choosing to leave poop alone
Pro tip: Practice this command daily with various tempting objects, not just poop. The stronger the command in general, the more reliable it'll be for poop.
Good training gets a lot easier when your dog isn’t bored out of their mind too. That’s where I’d mix in puzzle toys and enrichment instead of relying on command work alone → Outward Hound dog puzzles and toys
Method 6: Keep Them Busy
For boredom-based poop eating:
- Increase daily exercise (tired dogs don't have energy for gross habits)
- Provide puzzle toys and food-dispensing toys
- Practice training sessions daily (mental stimulation)
- Don't leave them alone in the yard with poop for entertainment
- Rotate toys to keep things interesting
This is usually where I stop overthinking and go back to a few enrichment brands I already trust → KONG Dog Toys
Method 7: Veterinary Intervention
If nothing else works, or if your dog has other symptoms, see your vet to rule out:
- Parasites (fecal test)
- Digestive disorders (EPI, IBD, malabsorption)
- Enzyme deficiencies
- Behavioral disorders requiring medication
Your vet may prescribe digestive enzymes, probiotics, or other supplements to address underlying issues.
| Method | Effectiveness | Time to Results | Best For |
|---|---|---|---|
| Immediate Cleanup | 100% (if consistent) | Immediate | All cases |
| Diet Upgrade | 80-90% | 1-2 weeks | Nutritional deficiency cases |
| Deterrent Products | 40-60% | 1-2 weeks | Own poop eating only |
| Pineapple/Pumpkin | 30-50% | 2-3 weeks | Worth trying, low risk |
| "Leave It" Training | 70-80% | 2-4 weeks | Motivated, trainable dogs |
| Increased Enrichment | 60-70% | 1-3 weeks | Boredom-based cases |
| Vet Treatment | 90-100% | Varies by condition | Medical cause cases |
Why Is My Old Dog Eating Poop All of a Sudden?
Sudden onset in senior dogs is a red flag.
If your older dog never did this before and suddenly starts, it's usually medical:
- Cognitive dysfunction (dog dementia) - Confusion about appropriate behaviors
- Digestive disorders developing with age - Enzyme deficiencies, IBD
- Medications - Steroids increase hunger dramatically
- Diabetes - Increased hunger despite eating
- Cushing's disease - Causes increased appetite
- Parasites - Older dogs can get them too
Don't assume it's "just old age." Get a full senior wellness exam including bloodwork, fecal test, and potentially cognitive assessment.
When Is It Necessary to Seek Veterinary Advice?
See your vet if:
- It's a sudden new behavior in an adult or senior dog
- Your dog shows other symptoms - vomiting, diarrhea, weight loss, lethargy
- They're eating poop AND grass excessively - sign of nausea or digestive upset
- Standard prevention methods aren't working after 4-6 weeks
- Your dog seems compulsive about it - can't be redirected, gets frantic
- They're losing weight despite normal eating
- You suspect parasites - visible worms in stool, scooting, bloated belly
What Percentage of Dogs Eat Their Poop?
Here are the actual statistics from veterinary studies:
- 16% of dogs are classified as "serious" stool eaters (caught 5+ times)
- 24% of dogs have been observed doing it at least once
- 85% of poop-eating dogs prefer fresh feces (less than 2 days old)
- Puppies do it more - up to 40% of puppies under 6 months
- Female dogs do it slightly more than males
- Dogs in multi-dog homes are more likely to develop the behavior
So if you're dealing with this, you're definitely not alone. Roughly 1 in 4 dog owners has caught their dog eating poop at least once.
Why When a Dog Poops Inside Does It Eat It?
This specific scenario—eating indoor accidents—is almost always anxiety or punishment-based.
The psychology:
- Dog has accident indoors (maybe wasn't let out in time, or is sick)
- Owner discovers it and reacts with anger, yelling, or punishment
- Dog learns: Poop in house = bad things happen to me
- Next time: Dog tries to hide evidence by eating it
- Owner finds no poop, so no punishment occurs
- Behavior is reinforced—eating poop = avoid punishment
This is heartbreaking because it's human-created. The dog isn't being gross—they're trying to avoid punishment.
✅ How to Fix This Specific Issue:
- STOP punishing accidents - It's making the problem worse
- Go back to basic house training - Frequent outdoor breaks, rewards for going outside
- Clean accidents with enzymatic cleaner - Remove scent markers
- Supervise more closely - Catch them before they eliminate indoors
- Consider crate training if house soiling is frequent
- Address why accidents are happening - Medical issue? Insufficient bathroom breaks? Anxiety?
That emotional side of it matters more than people think. A lot of the time this isn’t just about the poop at all—it’s about fear, attachment, routine, and how your dog relates to you. I went deeper into that here → Why Do Dogs Love You So Much?
Frequently Asked Questions About Dogs Eating Poop
Helping Your Dog Break the Habit: The Complete Action Plan
After dealing with Luna's poop-eating phase (and yes, it did stop), here's the realistic game plan that actually works:
Week 1-2: Foundation
- Vet visit - Rule out medical causes with fecal test and bloodwork if needed
- Switch food - Upgrade to high-quality, digestible brand
- Start immediate cleanup - Every. Single. Time. No exceptions.
- Begin "leave it" training - Practice with treats, toys, then poop
Week 3-4: Reinforcement
- Add deterrent - Try pineapple, pumpkin, or commercial product
- Increase enrichment - More walks, puzzle toys, training sessions
- Supervise ALL bathroom breaks - Interrupt before it happens
- Reward heavily for pooping and then coming to you without eating it
Week 5-8: Habit Breaking
- Continue all above consistently
- Gradually reduce supervision as success rate improves
- Maintain high-value rewards for leaving poop alone
- Address any setbacks immediately - don't let it become a pattern again
Timeline expectation: Most dogs show significant improvement within 4-6 weeks if you're consistent with multiple strategies. Complete elimination of the behavior may take 2-3 months.
The Bottom Line: You're Not Failing as a Dog Owner
That day when Luna ate her poop in front of my horrified parents, I felt like the worst dog owner ever. Like I'd somehow failed her.
But here's what I learned: poop eating is common, treatable, and not a reflection of your skills as a pet parent.
It's a symptom. Sometimes of diet. Sometimes of boredom. Sometimes of anxiety. Rarely, something medical. But it's always solvable.
The dogs who do this aren't broken or gross (okay, the behavior is gross, but THEY aren't). They're just being dogs—opportunistic scavengers following instincts that made sense in the wild but are deeply unfortunate in our living rooms.
Your job isn't to punish the behavior. It's to understand what's driving it and remove the motivation.
Fix the diet. Rule out medical issues. Provide mental stimulation. Remove access. Train an alternative. Be patient and consistent.
And remember: 1 in 4 dog owners is dealing with this same disgusting, embarrassing, totally-normal-but-still-gross problem.
You're not alone. And yes, it can get better.
