# How to Stop Your Dog from Eating Cat Poop and Food Dogs eat cat poop and cat food because it smells and tastes appealing to them, and because the litter box is often an easy, unsupervised snack station. The good news is that this habit is usually behavioral, not a sign of a serious illness, and you can change it with management, training, and a few simple changes at home. This article is educational and is not a substitute for veterinary diagnosis or treatment. ## Quick Answer - Manage access first. A covered box, a baby gate, or a box placed where only the cat can reach it solves most cases faster than training alone. - Feed the cat separately. Put cat food and the litter box in a room the dog cannot enter, or feed the cat on a counter or shelf the dog cannot reach. - Teach a solid "leave it" and "come" cue, then reward your dog for walking away from the box. - Give your dog more exercise, chew toys, and food puzzles so scavenging is less rewarding by comparison. - Call your vet if the behavior starts suddenly in an adult dog, or if your dog shows vomiting, diarrhea, weight loss, or a poor appetite. ## Why Dogs Eat Cat Poop and Cat Food ### It often starts as normal dog behavior Coprophagy, the technical term for eating feces, is a common behavior in domestic dogs [1]. A study of 44 healthy dogs found no significant differences in fecal bacteria or in carriage of common intestinal pathogens between dogs that ate poop and dogs that did not [1]. In other words, many dogs who do this are otherwise healthy animals doing something gross but ordinary. Cat poop has a few qualities that make it attractive. Cat food is high in protein and fat, so the waste still smells like food to a dog with a powerful sense of smell. Cat feces are also small, deposited in one predictable spot, and often left unattended. For a dog, that is a reliable, low-effort reward. Cat food itself is even more appealing. It is richer and more aromatic than most dog food, which is why many dogs prefer it when given the chance. If your dog is eating cat food regularly, that is a separate nutrition question worth reading about in [Can Dogs Eat Cat Food](/knowledge/veterinary-medicine/nutrition/can-dogs-eat-cat-food). ### Boredom, hunger, and habit Dogs who spend long hours alone, get limited exercise, or eat meals quickly may scavenge more. Eating cat poop can become a learned routine, especially if it happens every day at the same time. Some dogs also learn it from watching another pet. ### It can run in the family, so to speak Some dogs seem more inclined to eat feces than others, and the behavior can appear in puppies who are exploring the world with their mouths. If your dog also eats their own stool or other animals' stool, see [Why Does My Dog Eat Poop?](/knowledge/veterinary-medicine/parasitic-diseases/why-does-my-dog-eat-poop) for a broader look at the habit. ## Medical Causes to Rule Out Before Training Behavior is the most common explanation, but a veterinarian should check for medical reasons, especially if the habit is new. ### Digestive and nutritional problems Dogs with malabsorption, intestinal parasites, or diets that do not meet their needs may eat feces or other non-food items. Intestinal parasites are common in dogs and cats. In one study of 363 dogs and 345 cats, 41.6% of dogs tested positive for intestinal parasites, with Giardia the most frequently detected organism [2]. A fecal test is a simple, inexpensive way to check. Some parasites carried by pets can infect people, though the risk is often lower than owners fear. The species of Cryptosporidium and Giardia found most often in dogs and cats are largely host-specific, and human infections with these pet-adapted types are uncommon and mostly seen in immunocompromised people [3]. Still, good hygiene around the litter box matters, especially in homes with young children or anyone with a weakened immune system. ### Increased appetite and hunger Conditions that make a dog feel constantly hungry, such as diabetes, Cushing's disease, or a steroid medication, can drive scavenging. Sudden appetite changes deserve a veterinary visit. ### Pain or anxiety Some dogs eat unusual things when they are stressed, uncomfortable, or in pain. A dog who starts eating cat litter or feces after a move, a new baby, or a loss in the household may be reacting to stress. ## When Eating Cat Poop or Cat Food Becomes a Problem Occasional scavenging is unpleasant but often harmless. It becomes a real concern when any of these apply: - Your dog eats clumping cat litter. Clumping litter can form a mass in the stomach or intestines and cause a blockage. This is a medical emergency. - Your dog vomits, has diarrhea, stops eating, or seems painful in the belly. - Your dog guards the litter box or cat food and snaps at you or the cat. - Your cat is losing weight or not getting enough food because the dog eats it. - Your dog's weight, appetite, or energy level changes. - The behavior starts suddenly in an adult dog with no prior history. Cat food is not toxic to dogs, but it is not balanced for them. It is higher in fat and protein and lower in some nutrients dogs need. A dog who eats cat food regularly may gain weight or develop digestive upset.

Options include: - A covered litter box with the opening facing a wall, leaving just enough room for the cat. - A baby gate with a small cat door, or a gate the cat can jump but the dog cannot. - A top-entry litter box for cats who will use one. - A box in a room with a door, using a pet door that responds to the cat's microchip or a magnetic collar tag. - A sturdy shelf or counter the cat can reach and the dog cannot. Scoop the box at least once daily. Less waste in the box means less temptation. ### Step 2: Separate feeding stations Feed your cat in a different room, behind a closed door, or on an elevated surface. Pick up the cat's bowl as soon as the cat finishes. Do not leave cat food down all day in a dog-accessible spot. If your cat free-feeds, use a microchip feeder or a room the dog cannot enter. If your cat is the one eating the dog's food, the same logic applies in reverse. Feed the dog on a schedule, pick up the bowl, and keep the cat out of the room during meals. This is a common problem, and the fix is usually management, not training. ### Step 3: Train a reliable "leave it" Practice in short sessions with low-value treats first. 1. Hold a treat in your closed fist. When your dog stops nosing your hand, say "yes" and give a different treat from your other hand. 2. Move to a treat on the floor. Cover it with your hand or foot if needed. Reward your dog for backing away. 3. Practice near the litter box with the box blocked. Reward your dog for turning away and coming to you. 4. Add a "come" cue and reward heavily every time your dog leaves the box area. Keep sessions to a few minutes and end on success. If your dog already has a strong "leave it," use it every time you see the behavior start. ### Step 4: Increase exercise and enrichment A tired, mentally satisfied dog scavenges less. Try: - Two walks a day, plus a game of fetch or tug. - Food puzzles, snuffle mats, or scatter feeding instead of a bowl. - Safe chew items appropriate for your dog's size and chewing style. - Short training sessions that burn mental energy. Rotate toys so they stay interesting. A dog with nothing to do will find something to do, and the litter box is always available. ### Step 5: Manage mealtimes and diet Feed your dog a complete, balanced diet in measured meals. If your dog seems constantly hungry, ask your veterinarian whether the amount or type of food is right. Do not switch to cat food to satisfy hunger. It is not formulated for dogs. If your dog eats very fast, a slow feeder can help. Some dogs scavenge less when their own meals are more satisfying. ### Step 6: Keep the environment clean Scoop litter boxes daily and change litter regularly. Clean up any accidents in the yard promptly. If your dog eats their own stool, see [How to Stop a Dog from Eating Poop: Causes and Solutions](/knowledge/veterinary-medicine/anxiety-and-behavior-support/dog-eating-poop) for targeted steps. ## What Not to Do ### Do not punish your dog after the fact Dogs do not connect punishment to something they did minutes ago. Yelling, hitting, or rubbing a dog's nose in waste damages trust and can make the behavior worse by increasing anxiety. It can also teach your dog to eat the evidence faster or to hide the behavior from you. ### Do not rely on home remedies that have no support Adding pineapple, pumpkin, or meat tenderizer to food is a popular internet fix. There is no reliable evidence that these stop coprophagy, and they do not address the litter box access problem. If you want to try a food additive, ask your veterinarian first. ### Do not assume a muzzle is the answer A muzzle can prevent eating during walks, but it does not fix the cause and should never be left on an unsupervised dog. If you use one, choose a basket-style muzzle that allows panting and drinking, and introduce it slowly with rewards. ### Do not skip the vet because the habit seems harmless Most cases are behavioral, but parasites, diet problems, and other medical issues can look identical from the outside. A checkup and fecal test rule out the treatable causes. ## When to Involve a Veterinarian or Behavior Professional Call your veterinarian if: - Your dog ate clumping litter, a large amount of litter, or any non-food object. - Your dog is vomiting, has diarrhea, refuses food, or seems painful. - The behavior started suddenly in an adult dog. - Your dog is losing or gaining weight without a clear reason. - Your cat is losing weight or not getting enough to eat. - Your dog shows guarding, growling, or aggression around the litter box or food bowls. Ask for a referral to a veterinary behaviorist or a certified applied animal behaviorist if the behavior continues despite management and training, if your dog also eats non-food items like rocks or fabric, or if there is aggression in the home. These professionals can build a plan for complex cases. ## Limitations and When to Contact a Veterinarian This article covers common situations, but every dog and cat is different, and individual cases need a veterinarian who can examine your pet. Contact a veterinarian the same day if your dog ate clumping cat litter, is vomiting repeatedly, has a swollen or painful belly, or is straining to defecate. Go to an emergency clinic now if your dog is retching without producing anything, has a distended abdomen, is collapsing, or is having trouble breathing. These can be signs of a blockage or another emergency. Schedule a routine visit if the behavior is new, if your dog has soft stool or intermittent vomiting, if you have not had a fecal test done recently, or if you need help with a training plan. Bring a fresh stool sample if you can. Your veterinarian can check for parasites and discuss diet, enrichment, and whether a behavior referral makes sense. ## Frequently Asked Questions ### Is it dangerous for my dog to eat cat poop? Usually it is not immediately dangerous, and a study of healthy dogs found no difference in intestinal bacteria or pathogen carriage between dogs who ate poop and those who did not [1]. The bigger risks are parasites, clumping litter blockages, and the fact that cat waste can carry organisms that occasionally infect people [3]. Wash your hands after handling waste and keep the box clean. ### Why does my dog suddenly want to eat cat poop? A sudden change in an adult dog often points to a medical cause, such as intestinal parasites, a diet problem, or increased hunger from another condition. It can also follow a change at home, like a new pet or a move. Have your veterinarian examine your dog and run a fecal test before assuming it is purely behavioral. ### Will my dog get sick from eating cat food? Cat food is not toxic to dogs, but it is richer in fat and protein than dog food and is not balanced for a dog's needs. Eating it regularly can cause vomiting, diarrhea, or weight gain. If your dog stole a single meal, watch for stomach upset and call your vet if signs are severe or last more than a day. ### Can I just put the litter box somewhere the dog cannot reach? Yes, and this is often the fastest fix. A baby gate, a closed door, a top-entry box, or a microchip pet door keeps the dog out while giving your cat access. Combine this with daily scooping and a solid "leave it" cue for the best results. ### Do I need a trainer for this problem? Many owners solve it with management alone. If your dog keeps eating cat poop despite blocked access, daily exercise, enrichment, and training, or if there is guarding or aggression, a certified behavior professional can help. Your veterinarian can also rule out medical causes and refer you to a veterinary behaviorist if needed. ## Related Articles - [How to Stop a Dog from Eating Poop: Causes and Solutions](/knowledge/veterinary-medicine/anxiety-and-behavior-support/dog-eating-poop) - [Can Dogs Eat Cat Food](/knowledge/veterinary-medicine/nutrition/can-dogs-eat-cat-food) - [How To Stop Dog Poop In House](/knowledge/veterinary-medicine/clinical-methods/how-to-stop-dog-poop-in-house) - [Can You Feed Dogs Cat Food](/knowledge/veterinary-medicine/nutrition/can-you-feed-dogs-cat-food) - [Why Does My Dog Eat Poop?](/knowledge/veterinary-medicine/parasitic-diseases/why-does-my-dog-eat-poop) - [Cat Not Pooping but Eating Normally: Causes and When to Help](/knowledge/veterinary-medicine/digestive-and-urinary-care/cat-not-pooping-eating-normally) ## References 1.
