If you have dogs and cats living in the same household, you might have caught your dog eating cat poop from their litter box. This is rather disgusting and might gross you out, but there is a logical reason behind this behavior. Cats typically do not digest and absorb all of their dietary protein from their cat food; therefore, their faces tend to have a high protein content. This mean that their excrement has nutritional value that dogs recognize. This behavior is known as coprophagia. This is unhealthy for your pet and should be prevented and discouraged. A dog is prone to picking up parasites such as whipworm, roundworm, coccidia and giardia if this behavior persists and if you suspect this, you should take your dog to the vet to prescribe deworming medication. There are many different causes for this behavior.


This behavior could be genetically programmed or even inherited. Canines in the wild like wolves and coyotes will often scavenge the waste from other animals if they cannot hunt prey. This is a way they can get some vitamins and minerals. Having a cat with a litter box in your house might reawaken this instinct in your dog even if they are getting plenty of food.

This behavior could also be inherited from their mother. When a dog is nursing her pups, she often licks them to stimulate their bowels and bladders before eventually eating their waste. This keeps their environment clean and hygienic. Pups could witness this behavior by their mother and copy it.

Some dogs might indulge in cat poop because of stress or boredom.

Dogs have fewer taste buds than us humans and therefore are less likely to find things to be disgusting to eat.

Why you should keep your dog out of the litter box
  • It is bad for your dog’s health. Cat poop can contain parasites such as roundworm, coccidia, and whipworm. If your dog contracts these, they will need veterinary treatment.
    It is unhygienic for humans also. If your dog is eating cat poop, they are surely spreading bacteria and germs around the house to people.
  • This behavior can be very unsettling to your cat. Cats can be put off from using their litter tray if the dog is invading their personal toilet time all the time. Many cats suffer from ‘stage fright’ when going to the litter.

Solving This Yucky Problem

There are a few different ways you can approach your dogs poop eating habits.

Move the Litter Box

Place the cat’s litter tray or box in a place where the dog cannot access it. Another approach is to confine your dog away from the room in which the litter tray is in. This is, of course, dependent on housing circumstances and whether you can limit an area from a dog but not restrict the cat at the same time.

Train The Dog

As previously mentioned – This behavior could be down to malnutrition, stress, boredom or an inherited behavior. You could investigate what could be causing it and work to resolve it. You could consider crating your dog as it is a useful tool for house training as well as providing your pet with a den to relax in.

Invest in a Dog Proof Litter Box

Getting a dog proof litter box is the best option for keeping your dog out of the cat litter. There are loads on the market each with their own advantages and features. Of course, they range from budget litter trays to more superior ones.

Many of these litter boxes could be more accurately described as dog resistant rather than dog proof, but this depends on the size of your dog. It’s fairly obvious to notice that smaller dogs are closer to the scale of a cat, therefore, more likely to be able to access a litter box. But on the other hand, cats are more acrobatic and are able to jump higher than a dog.

There are two main designs of dog proof litter trays.

Top Entry

side-entry-dogproof-litterboxThese trays are essentially litter box with 4 solid walls and an entry hole on the roof. This design makes it easy for an acrobatic cat to jump up and enter, while the less acrobatic dog would struggle to climb up. This is, of course, subject to the size of the dog – would struggle even to fit inside the hole. Some large dogs that tower over the litter box would (in theory) be able to poke their head inside the entrance. These types of litter boxes are ideal for people with small and medium size dogs.

Side Entry

side-entry-dogproof-litter-boxThe side entry designs typically consist of a litter box with a wide entrance that leads into a sub-compartment that has another staggered entrance into the main litter compartment. This means it is ideal for a slender moving cat to gain access to but the more cumbersome moving dog would struggle. Of course, this is true only for small dogs, as the larger dogs would find it impossible to gain access to the litter. These types of litter boxes are ideal for people with large dogs.

Do you need a pet proof litter box?

  • Owners of dogs that have eaten dog poop before
  • Owners of dogs that have a proven record of eating waste and rubbish
  • People that leave their dogs home alone during the working day and want maximum peace of mind
  • Owners of cats that require maximum privacy when going to the litter box

Cat Litter Box Factors to Consider

Entrance – Quite an important thing to consider which depends greatly on what size dog you have. If you have a small dog, you are best off going for a top entrance litter tray as a small breed of dog will struggle to jump up and get into the litter tray whereas a large dog could just tower above the box and poke their head down through the entrance. If you have a large dog, then the best option would be a side door as a large, cumbersome dog would be unable to enter through the first entrance due to their size. The dog would also be unable to poke their neck through the second inner opening as they are staggered on different sides of the box.

Size – The size of your dog proof litter box greatly depends on your personal preference and factors completely unrelated to the dog element to this buyer’s guide. Many cats can not comfortably maneuver or fit inside most of the traditional commercial litter boxes on the market today; therefore, it is advised by DoggyToggery always to opt on with a large size to play it safe. If you have an elderly cat, it is also important to give them a large litter environment as arthritis makes it difficult for them to move in and out of the litter box entrance. The litter area should be big enough for cats to get inside, maneuver around, do their poop business and dig a hole to cover it up.
