How to Stop Your Dog from Eating Poop: A Practical, Vet-Reviewed Plan

Most owners discover this the same way. You're on the patio with a coffee, watching your dog do their business in the yard, everything perfectly normal — and then they turn around, sniff what they just left behind, and eat it before you can get a word out.

Then comes the part that really lands: your dog trots back over, tail going, looking thoroughly pleased with themselves, and tries to lick your face.

The clinical name for this is coprophagia, and if you're reading this you've almost certainly just witnessed it. Your dog isn't broken. Below is what actually works to stop it, and what's a complete waste of money.

Why Do Dogs Eat Poop?

Coprophagia is far more common than most owners assume — survey data puts it at roughly 16 to 23% of dogs doing it at least occasionally, and the majority of puppies grow out of it. The usual drivers are leftover puppy instinct, genuine hunger, attention-seeking (negative attention still counts as attention), or plain boredom and anxiety. And yes, cat poop is especially attractive, because cats eat high-protein diets and the result smells like food to a dog.

What Fails, Reliably

Pineapple and pumpkin. Most dogs eat the pineapple happily and then carry on eating poop just as happily. Research on commercial coprophagia deterrents has put their success rate in the 0–2% range. The "no poop" chews. Same story, and they are not cheap. Yelling and chasing. This one actively backfires — being chased around the yard is a game, and you've just made the habit more rewarding than it was. Muzzles. A determined dog comes back with poop smeared on the muzzle instead, which solves nothing and adds a new problem.

The Three-Week Reset That Works

Week 1: Eliminate Access Completely

Your dog goes outside on a leash, every single time. The moment they finish, call them away with a piece of chicken and clean up immediately. If a cat's litter box is the target, fit a baby gate the cat can clear but the dog can't. You cannot train a dog out of eating poop while they still have free access to it — access control comes first, always.

Week 2: Build a New Default Behavior

The moment your dog finishes pooping, say "Yes!" brightly and jog backward a few steps. They'll follow, because you have chicken and you are now the most interesting thing in the yard. Within about five days, most dogs start looking at you expectantly after pooping instead of looking down at the poop.

Week 3: Test and Reinforce

Now work off leash in the yard with you standing nearby. Call your dog after every poop. If they come, jackpot reward. If they so much as glance back at it, jog away playfully and pay them for following you instead. By the end of week three you should be at roughly 90% reliability, with the rest fading out over the following month.

What Helps Along the Way

A higher-fibre food with a tablespoon of plain canned pumpkin is worth trying. So is more exercise and a couple of puzzle toys — a tired dog has less spare capacity for strange hobbies. And clean the yard as though guests are arriving: every time, no exceptions. That one habit does more work than anything you can buy.

Run consistently, this holds. The end state you're aiming for is a dog who finishes pooping, ignores it entirely, and turns to look at you waiting to be paid.

The Leash Habit That Stops It

What sticks is removing the opportunity, not the urge. On walks, keep your dog on a short leash through the known trigger zones — other dogs' yards, that one corner of the park — and the instant their head drops, say "leave it" and redirect with a treat. Give it about three weeks and the reflex breaks: your dog glances at it, then looks up at you for the treat instead. Off-leash freedom before that point simply buys more practice at the habit you're trying to end.

The Pineapple Myth, Debunked

You'll read "feed them pineapple, it makes poop taste bad." For most dogs it does nothing, and for some it just adds sugar. The reliable levers are: pick up immediately (no access), keep them fed on schedule (hungry dogs scavenge), and the leash redirect above. The treat side of that is in these training-treat hacks, and the full foundation is the new dog owner's guide.

When It's Just an Adolescent Phase

Plenty of dogs pick this habit up as teenagers and drop it again once they mature. That's not a reason to wait it out passively. Rule out a dietary gap with your vet first, then make pickup immediate on walks and put a well-paid "leave it" cue in place. Most cases resolve through a combination of maturity and management, not through a supplement.

It often overlaps with other mouthing habits; our notes on why dogs eat grass and training regressions cover the bigger picture. Keep the yard clean and the reward for checking in with you higher-value than the snack.
