If you have ever caught your dog sneaking into the litter box for a snack, you are not alone — and you are definitely not a bad dog owner. Dogs eating cat poop is one of the most common and most disgusting habits dog owners deal with. It is embarrassing when guests are around and worrying when you think about germs.
The good news is that this habit is very fixable. Most dogs do it because cat poop smells and tastes appealing to them, not because they are being naughty. With a few smart changes around the house and some patient, positive training, you can break the habit for good. This guide covers why dogs do it, how to manage the litter box, and how to teach your dog to leave it alone — all without scolding or punishment.
Why Dogs Love Cat Poop So Much
To understand how to stop the behaviour, it helps to know why it happens. Cat food is usually higher in protein and fat than dog food, and cats do not digest all of it. That means their waste still smells like food to a dog’s powerful nose. To your dog, the litter box is basically a snack bar that refills itself.
- Natural instinct. Puppies explore the world with their mouths, and scavenging is normal dog behaviour.
- Curiosity and boredom. A bored, under-stimulated dog is more likely to go looking for “entertainment,” and the litter box is an easy target.
- Attention-seeking. If raiding the litter box gets a big reaction from you — even a horrified one — your dog may keep doing it just for the attention.
- Hunger or dietary gaps. Some dogs may be drawn to waste if they are very hungry or not absorbing nutrients well. This is less common than simple attraction to the smell, but worth keeping in mind.
If you want to dig deeper into the behaviour, this guide on why dogs eat poop and what you can do about it covers the common reasons in more detail. Most of the time, though, the fix is about management and training — which is exactly what we will cover next.
Step 1: Make the Litter Box Inaccessible
Training takes time, so your first job is to remove the opportunity. If your dog simply cannot reach the litter box, the habit cannot continue while you work on the rest. This single change solves the problem for many households overnight.
- Use a baby gate with a cat-sized gap. Install a baby gate in the doorway of the litter box room, raised just high enough for your cat to slip underneath (or use a gate with a small pet door).
- Try a top-entry or covered litter box. Many dogs will not bother with a top-entry box, and a covered box with a small entrance is harder for larger dogs to raid. Make sure your cat is comfortable with it first — some cats refuse covered boxes.
- Put the box behind a door with a cat flap. A simple interior cat door lets your cat come and go while keeping the dog out completely. This is one of the most reliable long-term solutions.
- Place the box somewhere elevated or dog-proof. A sturdy shelf, a laundry room with a cat door, or a litter box cabinet with a cat-sized entrance can all work, as long as your cat can reach it easily.
Whichever option you choose, keep the litter box clean. Scoop at least once a day — ideally twice. Less waste sitting around means less temptation, and it is also better for your cat’s health and comfort.
Step 2: Teach a Rock-Solid “Leave It”
Management stops the habit at home, but training stops it everywhere else — at a friend’s house, on a walk, or in the garden. “Leave it” is the single most useful cue for this problem.
Here is a simple, force-free way to teach it:
- Start with a treat in your closed hand. Let your dog sniff. The moment they pull away or look at you, say “yes!” and reward them with a different, better treat from your other hand.
- Move to an open hand. Hold the treat in your open palm. If your dog moves toward it, close your hand. When they back off, mark with “yes!” and reward from the other hand.
- Add the cue. Once your dog is turning away reliably, say “leave it” just before you present the treat. Reward every correct response generously.
- Practise with the treat on the floor. Place a treat on the floor and cover it with your hand if needed. Say “leave it,” and reward your dog with a high-value treat from your pocket when they ignore it.
- Build up gradually. Practise in different rooms, then in the garden, then on walks. Keep sessions short — five minutes is plenty — and always end on a success.
The key is that “leave it” should always pay off. If ignoring the gross thing earns your dog something even better, they will choose to ignore it. Never punish your dog for getting it wrong — that only teaches them to be sneaky about it.
Also teach a reliable recall (“come”) so you can call your dog away from the litter box area before they even reach it. A dog who happily runs to you for a treat is a dog who is not raiding the litter box.
Step 3: Supervise, Interrupt Gently, and Redirect
Until the habit is fully broken, supervision matters. If your dog is loose in the house unsupervised, they have the chance to practise the behaviour — and every time they succeed, the habit gets stronger.
- Watch for the signs. Dogs heading toward the litter box often move with purpose: ears up, heading straight for the cat’s room. If you see it, calmly call them to you and redirect to a toy or treat puzzle.
- Interrupt without drama. If you catch your dog in the act, stay calm. A loud yell or chase just adds excitement and teaches your dog to do it when you are not watching. Call them away, reward them for coming, and go and clean the box.
- Use a leash indoors if needed. For persistent cases, keeping your dog on a light house leash for a week or two lets you guide them away from the litter box area and reward good choices, without any confrontation.
The goal is to make the litter box boring and everything else more rewarding. Dogs repeat what works for them — so make sure raiding the box never works, and coming to you always does.
Step 4: Keep Your Dog Busy and Fulfilled
A tired, mentally satisfied dog is far less likely to go hunting for trouble. If boredom is part of the picture, enrichment can make a real difference:
- Daily exercise. Make sure your dog gets enough physical activity for their age and breed — walks, play, and off-leash running where safe.
- Food puzzles and enrichment toys. Feed part of their daily food from a puzzle feeder, snuffle mat, or stuffed Kong instead of a bowl. This gives their brain a job and satisfies the urge to forage in a healthy way.
- Training games. Short daily sessions — even five minutes of tricks or “find it” games — tire a dog out mentally and strengthen your bond.
A dog with a full, interesting day simply has less reason to go looking for excitement in the litter box.
Step 5: Check the Basics — Diet, Health, and Routine
Most cases of cat-poop eating are about opportunity and smell, not illness. Still, it is worth checking the basics:
- Is your dog getting enough food? A dog on a very restricted diet, or one who always seems ravenous, may be more motivated to scavenge. If you are unsure about portions, ask your vet for guidance rather than guessing.
- Is the behaviour new or sudden? A dog who has never done this before and suddenly starts may be worth a vet check, especially if there are other changes — weight loss, a dull coat, diarrhoea, or increased appetite.
- Is your cat healthy? If your cat has diarrhoea or a possible parasite issue, your dog could pick up germs from their waste. Keeping both pets on regular vet check-ups and parasite prevention helps protect everyone.
Do not add supplements or “taste deterrent” products without talking to your vet first. These products have mixed results at best, and they do not fix the underlying opportunity. Management and training are far more reliable.
If you have recently brought a new dog or cat into the home, the adjustment period can also stir up this kind of behaviour. This guide on how to introduce your cat to a new dog in the house can help you set up the household so both pets feel secure — and a calmer household often means fewer unwanted habits.
What NOT to Do
It is tempting to react strongly when you catch your dog in the act — but punishment almost always makes this problem worse, not better. Avoid these common mistakes:
- Do not scold, yell at, or physically punish your dog. This does not teach them that cat poop is bad. It teaches them to do it when you are not around, or to eat it quickly before you notice. It can also damage your dog’s trust in you.
- Do not rub their nose in it. This is an old myth and it does not work. Your dog will not connect the punishment with the behaviour in the way you hope, and it is simply unkind.
- Do not chase your dog away from the litter box. Chasing turns it into a game and adds excitement to the whole event.
- Do not rely on punishment-based tools. Shock collars or spray bottles used as punishment may suppress the behaviour temporarily, but they often create anxiety or new behaviour problems — and they do not teach your dog what to do instead.
- Do not remove the litter box or punish the cat. Your cat needs safe, easy access to their box at all times.
The kindest and most effective approach is always the same: prevent the behaviour, reward the behaviour you want, and be patient. Dogs learn through repetition and reward, not through fear.
When to See a Vet
Most dogs who eat cat poop are perfectly healthy, and the habit is a management and training issue. Still, see your vet if:
- Your dog has vomiting, diarrhoea, or stomach upset after eating cat waste. Cat faeces can carry parasites and bacteria, so digestive symptoms after exposure are worth checking out.
- The behaviour started suddenly in an adult dog who never did it before, especially alongside weight loss, increased appetite, or changes in coat or energy.
- Your dog seems unwell in other ways — lethargy, loss of appetite, or anything that worries you.
- Your cat has diarrhoea or a known parasite issue, since your dog may need checking too.
- You have tried management and training consistently for several weeks with no improvement, and you want to rule out any underlying health factor.
Bring a note of when the behaviour started and any other symptoms you have noticed. Your vet may suggest a faecal test or a diet review, or simply reassurance that your dog is fine and the habit is behavioural.
Frequently Asked Questions
Is it dangerous for my dog to eat cat poop?
It can be, but it is not usually an emergency. Cat poop may contain parasites or bacteria that can upset your dog’s stomach. Most healthy adult dogs pass it without serious harm, but puppies, elderly dogs, and dogs with weaker immune systems are more at risk. If your dog develops vomiting or diarrhoea afterwards, contact your vet.
Will my dog grow out of it?
Some puppies do, as they mature and their curiosity fades. Many adult dogs will not stop on their own, though — because the behaviour keeps rewarding itself every time they succeed. Management plus training is the reliable route, rather than waiting and hoping.
Why does my dog only eat cat poop and not dog poop?
Cat poop smells more like food to dogs because of the higher protein and fat content of cat food. That is also why the habit often continues even in dogs who are otherwise well-fed and well-behaved.
Do taste deterrent products work?
Results are very mixed. Many dogs simply ignore the deterrent or switch to a different target, and deterrents do nothing about access. A dog-proof litter box setup and “leave it” training are far more dependable, and you should talk to your vet before adding any product to your dog’s or cat’s food.
How long will it take to stop the habit?
It depends on how long the habit has been going, and how consistent you are. With the litter box secured and daily short training sessions, many owners see a big improvement within two to four weeks. Older, well-practised habits may take a couple of months. Consistency matters more than speed — every successful raid sets progress back, so prevention is half the battle.
Final Thoughts
Yes, it is gross. Yes, it is frustrating. But eating cat poop is a normal, fixable dog behaviour — not a sign that your dog is broken or badly behaved. Secure the litter box, teach “leave it” with patience and plenty of rewards, and keep your dog busy and fulfilled. With a bit of consistency, most dogs learn to walk straight past the litter box without a second glance.
