Short answer: most dogs eat poop because it's normal canine behavior — not because something is wrong with them. Researchers call it coprophagia, and studies suggest roughly one in four dogs has done it at least once. The most common drivers are instinct, boredom, stress, and simple access. Diet deficiency gets blamed a lot, but it's rarely the culprit. The fix is almost always the same three things: pick it up fast, teach a solid "leave it," and give your dog something better to chew on.
I'm Preston Smith, co-founder of Bully Sticks Central. We get this question constantly from customers, so here's the plain version.
Why do dogs eat poop?
It's instinct, and it's old
Mother dogs clean up after their puppies for the first few weeks — that's hardwired den-keeping behavior. Puppies watch and copy. Wild canines do the same thing to keep the den area free of parasites. A 2018 study out of UC Davis, covered by the American Kennel Club, found stool-eating dogs were no more likely to have diet or health problems than dogs who never touched it. It's just behavior.
Boredom and under-stimulation
A dog left alone in a yard with nothing to do will find a job. Sometimes that job is investigating what's on the ground. Dogs who get regular exercise, training, and something to chew simply have less reason to.
Stress and anxiety
New house, new baby, new schedule, crate confinement, harsh punishment around potty training — any of it can trigger it. Dogs who were punished for accidents sometimes eat the evidence, which is a good reason to skip punishment entirely.
Attention-seeking
If your dog grabs a pile and you sprint across the yard yelling, congratulations — you've invented a game. Big reactions reinforce the behavior.
Actual medical causes (the short list)
Sometimes there is a real reason: parasites, exocrine pancreatic insufficiency, malabsorption issues, diabetes, or a side effect of steroids that spikes appetite. VCA Animal Hospitals notes that a sudden onset in an adult dog who never did it before is worth a vet visit. Same goes if it comes with weight loss, vomiting, diarrhea, or a huge jump in hunger.
Is it dangerous?
Usually not immediately, but it isn't harmless. Feces can carry roundworms, whipworms, giardia, coccidia, and parvovirus. Cat litter box raiding adds toxoplasma and the risk of a litter obstruction. Keep your dog on year-round parasite prevention and mention the habit to your vet at checkups.
How do you stop a dog from eating poop?
1. Remove access — this does most of the work
Pick up the yard immediately, every time. Walk your dog on leash so you control what they can reach. Move the litter box behind a baby gate or somewhere the cat can get and the dog can't. No access, no habit. This single step fixes more cases than everything else combined.
2. Teach "leave it" and pay well for it
Train it indoors with something boring first, then work up to the real thing outside. When your dog looks away from the pile and back at you, that's the moment to pay — and pay generously. The ASPCA recommends positive reinforcement over punishment for exactly this kind of behavior. Yelling or scaring your dog usually makes them sneakier, not cleaner.
3. Trade up instead of chasing
When your dog gets to something first, don't chase. Call them to you and trade for something better. This is where a genuinely high-value chew earns its keep — a single-ingredient chew beats a pile of poop every time, and it teaches your dog that coming to you pays better than running from you.
4. Give the chewing drive somewhere to go
Dogs need to chew. It's not optional, and if you don't pick the outlet, they will. Our bully sticks are 100% natural, single-ingredient, 100% real meat, fully digestible, and contain no rawhide — ethically sourced from grass-fed American and Argentinean farms and 100% high-quality guaranteed. A dog working on a bully stick for twenty minutes is a dog not patrolling the yard. If you've got a puppy going through this phase, we wrote up sizing and safety in bully sticks for puppies.
5. Exercise and mental work
A tired dog is a less creative dog. Two real walks a day, some sniffing time, five minutes of training, a puzzle feeder. It's unglamorous and it works.
6. Rule out the medical stuff
If it's new, sudden, or paired with any other symptom, call your vet. A fecal test and a quick exam rule out the short list above and save you months of guessing.
What about deterrent additives?
You'll see products that claim to make stool taste bad — meat tenderizer, pineapple, MSG-based powders, commercial additives. Success rates in the UC Davis research were under 2%. They also only work if every dog in the house is dosed. Save your money and fix the access problem instead.
How long does it take?
If it's a puppy, most grow out of it by around a year old with consistent cleanup. If it's an adult dog with an established habit, budget a few weeks of strict management plus training. The dogs who backslide are almost always the ones whose owners got lax about picking up the yard.
The bottom line
Poop eating is gross, common, and fixable. It's rarely a sign your dog is sick or your food is bad. Control access, reward the right choice, give the chewing drive a real outlet, and check with your vet if anything about it seems sudden. Most dogs move past it.
