How to Stop Your Dog From Eating Poop (Coprophagia Solutions That Actually Work)

TL;DR: Dogs eat poop for a mix of reasons: nutritional gaps, boredom, stress, attention, instinct, or just because it tastes interesting to them. The fix is rarely one thing. The combination that actually works: pick up poop immediately, supervise outdoor time, address any underlying medical or dietary issues, use a deterrent (pineapple sometimes works, commercial products work better), and reward your dog for leaving poop alone. Pure deterrents without behavioral training rarely fix the problem long-term.

Coprophagia, the technical name for eating poop, is one of the grossest, most embarrassing, and most common dog behavior problems. About 1 in 4 dogs will eat poop at some point, and about 1 in 6 will do it regularly. The good news: it's almost always fixable. The bad news: it takes more than just one product or trick. For background on why this happens, see our existing article on why dogs eat poop. This guide focuses on the specific tactics that actually stop the behavior.

First: Figure Out Why

The fix depends on the cause. The most common reasons:

• Nutritional deficiency. If your dog isn't absorbing enough nutrients from their food, they may try to recoup them by eating stool. This is especially true if the diet is low in digestive enzymes, fiber, or specific nutrients.
• Hunger. Underfed dogs may eat poop as supplemental calories. If your dog is on a weight-loss diet and acting hungry, the diet may be too restrictive.
• Boredom. Dogs left alone in the yard for long stretches can develop coprophagia as a self-entertainment habit.
• Anxiety or stress. Stressed dogs sometimes develop compulsive behaviors, including stool eating.
• Attention-seeking. You reacted big the first time. Now it's a strategy.
• Mother behavior. Mother dogs clean up after their puppies by eating waste. Some puppies pick up the habit and never drop it.
• Medical issues. Diabetes, Cushing's disease, thyroid disease, parasites, EPI (exocrine pancreatic insufficiency), and malabsorption disorders can all cause coprophagia.

If your dog suddenly starts eating poop after never doing it before, see your vet to rule out medical causes. This is especially important for senior dogs.

Step 1: Pick Up Poop Immediately

The single most effective intervention is also the most boring: don't let poop sit around. The longer it's available, the more opportunity for the behavior to happen. Get into the habit of picking up immediately after your dog goes, both your own yard and on walks.

For multi-dog households, this is even more important. Many coprophagic dogs eat other dogs' poop, not their own. Quick cleanup = no temptation.

If your dog is in a yard or area where poop accumulates, do a sweep every day or two. A bucket and a scoop, a few minutes, no exceptions.

Step 2: Supervise Outdoor Time

Don't let your dog out unsupervised if they have a poop-eating habit. Go with them. Watch what they're doing. If they go for stool, redirect immediately with a "leave it" command and a treat.

The most labor-intensive part of fixing the behavior, but it's also the part that builds the new habit. Every time your dog passes up poop for a treat, the new association strengthens. Every time they get a chance to eat poop unobserved, the old association strengthens.

Teach a Solid "Leave It" Command

If your dog doesn't already know "leave it," teach it now. The basic process:

1. Hold a treat in your closed fist. Let your dog sniff, lick, paw at it.
2. When they stop trying and back off, say "yes" or click, then give them a different (better) treat from your other hand.
3. Repeat until they back off as soon as you present the closed fist.
4. Move to having the treat in your open palm. Same process. Cover the treat if they try to grab it.
5. Progress to treats on the floor. Then to other items. Eventually to poop on walks.

"Leave it" is among the most useful commands you can teach. It applies to poop, dropped food, dead animals on walks, dangerous objects, and a hundred other situations.

Step 3: Try Dietary Changes

If you suspect a nutritional cause, talk to your vet about food options. Things to consider:

• Higher-quality food. Cheap kibble with a lot of fillers may not be meeting your dog's nutritional needs. A food with real meat as the first ingredient and fewer fillers may help.
• Higher fiber. Adding fiber (canned pumpkin, green beans, fiber supplements) can sometimes reduce coprophagia.
• Digestive enzymes. A digestive enzyme supplement may help dogs who aren't absorbing nutrients efficiently. Talk to your vet first.
• More frequent meals. Hungry dogs eat poop. Two smaller meals plus a midday snack may help.
• Probiotics. A healthier gut microbiome can sometimes reduce the behavior.

Step 4: Try a Deterrent

Deterrents work by making the poop taste bad to the dog. The idea: feed something that, when it comes out the other end, makes the stool unappetizing.

Pineapple

The classic home remedy. The theory: pineapple contains bromelain, which supposedly changes the smell or taste of stool. Some owners swear by it; others get nothing from it. If you want to try, give a small piece of fresh pineapple (not canned, which has too much sugar) with each meal. A small dog gets a few small pieces, a large dog gets a few thick slices.

Honest assessment: pineapple works for some dogs, not others, and the dog has to eat the pineapple voluntarily. Some dogs hate it. Some won't eat enough to make a difference. Try for two weeks; if no change, move on.

Papaya

Same general theory as pineapple. Contains papain, a digestive enzyme. Some owners report success. Mix a few small pieces into food.

Commercial Products

Several commercial products are specifically formulated to make stool less appetizing. Common active ingredients include yucca, MSG, or specific enzymes. Examples include Solid Gold "S.E.P.", NaturVet "Coprophagia Soft Chews", and similar products from various manufacturers. Read reviews, ask your vet for a recommendation, and give the product a fair trial of 4-6 weeks.

Hot Sauce or Bitter Apple on Stool

Some owners spritz existing stool with hot sauce, bitter apple spray, or red pepper. The idea: dog tries to eat it, gets a bad taste, learns to associate stool with unpleasantness. This can work but requires you to do it consistently, and it only works on stool you've already spotted, not on stool your dog finds while you're not watching.

Step 5: Reward the Right Behavior

This is the part most people skip. Deterrents tell the dog what not to do. They don't tell the dog what to do instead. The behavior you want is "see poop, look at owner, get reward and move on."

To build that:

• Carry high-value treats on walks.
• When your dog notices poop and doesn't go for it (or responds to "leave it"), reward heavily.
• If your dog ignores poop on their own, reward generously. You want this to be the most rewarding choice they can make.
• After several weeks of consistent reward, the new behavior should be established and you can fade the treats to occasional.

What Doesn't Work

A few common approaches that don't help (and sometimes make things worse):

• Punishment after the fact. Dogs don't make the connection between past behavior and current punishment. Yelling at your dog for eating poop they ate 10 minutes ago does nothing useful.
• Punishment in the act, harshly. Yelling or hitting in the moment can create anxiety and make the behavior worse, or make your dog hide it from you (they still eat poop, they just do it when you're not looking).
• Putting the dog in the yard alone and hoping they figure it out. They will figure it out, just not the way you want.
• One-and-done deterrents. Most dogs need a multi-pronged approach. Pineapple alone, or "leave it" alone, often isn't enough.

What to Do If Your Dog Already Ate Poop

If you caught your dog in the act and they already swallowed:

• Don't panic. Eating poop is gross but usually not dangerous.
• Brush their teeth or offer a dental chew. Both for the smell and to reduce bacteria transfer.
• Watch for symptoms. Most dogs are fine, but eating stool can transfer parasites (giardia, roundworms, hookworms), so watch for diarrhea, vomiting, or weight loss over the following weeks.
• Make sure parasite prevention is current. Regular deworming protocols matter even more for dogs who eat poop.

If your dog ate the poop of an unknown animal (especially wild animals), or a sick dog's stool, or stool from a dog on chemotherapy (some chemo drugs are excreted in stool), call your vet.

How Long Does It Take to Stop the Habit?

Realistic timeline: 4-8 weeks of consistent intervention before you see the behavior fade. Some dogs change faster, some take longer. The longer the dog has been doing it, the longer it takes to retrain.

Don't get discouraged by setbacks. If your dog goes a month without eating poop and then does it once, that's still progress. The goal is overall reduction, not perfection.

When to See a Vet (or Behaviorist)

If the behavior persists despite 2-3 months of consistent effort, or if any of these apply:

• The behavior is new (your previously normal dog suddenly started)
• Your dog is losing weight despite eating normally
• Your dog has diarrhea, loose stool, or other GI symptoms
• Your dog seems unusually hungry all the time
• The behavior is paired with other anxiety symptoms (excessive licking, destruction, vocalization)
• Your dog is a senior

Vets can rule out medical causes. Veterinary behaviorists can help with stubborn behavioral causes.

The Short Version

Coprophagia is common, frustrating, and fixable, but rarely with one quick trick. The combination that works: clean up immediately, supervise, teach "leave it," consider dietary changes, try a deterrent, and reward the right behavior consistently for several weeks. If nothing works after a few months, see your vet to rule out medical causes.
