If you have dogs and cats living under the same roof, then at some point you may have caught your dog digging through the litter box. Using the best dog proof litter box can prevent your dog from having access to your cat’s litter box and attempting to get inside to eat a cat’s droppings. This is a common behavior in dogs, but it can lead to a huge mess in the home and may even cause your cat to avoid using their litter box altogether. As both a dog and cat owner, I decided to create this buyer’s guide in order to help other pet owners find the perfect litter box for their felines, one that will block man’s best friend from digging around and creating a huge mess. Of course, not all litter boxes are created equal, and even some that are labeled as dog proof really aren’t. Because of this, I’ve also included four models of dog proof litter boxes that each earned a high rating for their dog-proof design, durability, and solid construction. Below, you’ll find a comparison chart for the models that are on my list, their top features, and their rating.

The groove’s on top of the box will also work to remove any litter that sticks to a cat’s paws.

Dog Proof Litter Box Buyer’s Guide

Many dog and cat owners are perplexed by a dog’s desire to dig through a dirty litter box and consume a cat’s droppings. So, why do dogs do this?

Cats do not digest or absorb dietary protein from their food. Because of this, their feces have a very high protein content. This means that a dog finds nutritional value in eating the feces. This type of behavior is referred to as coprophagia and it can result in health issues later down the line if your dog doesn’t stop this behavior.

Aside from preventing health issues in your dog there are many benefits to using a dog proof litter box, which I’ll discuss below.

Benefits of Dog Proof Litter Boxes

  • A dog proof litter box is designed to prevent a dog from digging around and creating a mess. The unique design of these litter boxes will help to cut down on messes since a dog will no longer be able to use their paws to dig inside the box in search of feces, scattering litter everywhere.
  • These litter boxes often feature a covered design that will also minimize messes that are caused by cats who love to kick out litter.
  • There are many style options available, so you can choose a box based on the size of your cat and dog.
  • If you have a persistent dog, then you can invest in a large, durable dog proof box, such as the decorative models that are designed to look like end tables and plant holders.
  • Many of these litter boxes are very affordable, so you can purchase one per cat and place them in a variety of locations around the home.

Now that you know more about the benefits this type of litter box has to offer, let’s learn more about the unique features they possess and how it can solve some of your pet problems around the home.

Other Important Features

Dog proof litter boxes are designed to prevent a dog from accessing a cat’s droppings, ensuring your cat can use their litter box undisturbed.

However, before you purchase this type of litter box there are some factors you’ll need to consider, such as where the litter box will be placed and how many cats will be using it.

Litter Box Location

If you plan on placing the box in a smaller area, then you may need a top-entry style box since these boxes have smaller footprints and tend to be smaller than a domed litter box or a traditional rectangular litter box. For a larger area, you’ll have more freedom in terms of the style you choose. Large style dog-proof models can include dome, self-cleaning, and enclosed table or bench style models.

Multi-Cat Households

If you live in a multi-cat household, then you’ll need to purchase one box per cat, plus one. This is because some cats are very picky about their litter boxes and may not use the same box that another cat has used.

Dealing with a Persistent Dog

Another factor to consider is just how persistent your dog will be if he initially cannot get inside the box. Many dogs can easily be deterred from getting inside a litter box by a smaller entryway or higher walls. Top-entry boxes are too tall for many dogs to lean their heads in and it doesn’t allow enough room for them to dig around. Enclosed boxes and dome style boxes will also restrict a dog’s access by using an entry the dogs cannot fit their heads into. A dog that’s very persistent can be deterred by table or bench style boxes since these are considered the most durable.

Cat Size

If you have a large cat, then you’ll need a larger litter box, one that’s stable and will not move, rock, and cannot be flipped over. A smaller box may flip over and may not allow your cat to use their litter box comfortably, which can lead to inappropriate elimination around the home.

Types of Cat Litter Boxes

There are several types of dog proof litter boxes on the market, which I’ve discussed above. However, let’s go a little more in-depth concerning the styles you’ll have to choose from.


These boxes are disguised as pieces of furniture, such as plant holders, benches, and end tables. These are often a great choice if you have a more persistent dog, since the entry hole is very small and this type of box cannot be easily tipped over or broken into. However, these boxes tend to be more expensive compared to other style options.

Domed and Covered

Domed and covered boxes are a more affordable alternative. These boxes are either igloo shaped or square shaped and are available in a variety of sizes. The cover will deter larger dogs from accessing the contents of the litter box, but a smaller dog may still be able to fit inside. However, the cover can make even a small dog think twice about entering the dark space. Your cat will also appreciate the cover since it will give them some privacy while they do their business. Yet, there are some cats that will refuse to use this type of box, simply because they cannot fit comfortably inside. A smaller litter box can prevent them from squatting, or they may be scared to enter the dark space. Fortunately, the covers are detachable, however, without the cover, the box loses its dog-proof design.


This is a great option that will work for many pet owners. Your dog will not be able to eat your cat’s droppings if the droppings have been promptly removed from the litter box, seconds after a cat defecates. This type of box can be pricey, but it will help to keep your home smelling fresh, will eliminate the problem of your dog eating feces, and will make your cat happier since the box will always be clean and ready for use. Before you purchase this type of box, you’ll have to consider the extra expenses of liners and the cost of crystal cat litter, which most models require you to use.

Point of Entry

When it comes to the points of entry, most dogs will attempt to enter the box from the top or side. For specially designed dog proof top entry models  top entry, a cat will enter the box through the top of the box. The top entry design will prevent your cat from tracking litter around the home, which is a huge plus for any cat owner and it features a narrow opening a dog will be unable to use. Side entry models are a good choice for smaller cats, but a larger cat may have trouble fitting inside.

Why Dogs Eat Cat Poop

Many pet owners will be surprised to learn how much their dog loves to feast on cat poop whenever they have the opportunity. While a pet owner will be disgusted, this type of behavior is actually completely normal. A dog is a scavenger by nature. With that being said, they will eat all types of things including sticks, garbage, and yes, even cat poop. While a human will think that cat poop smells disgusting, the scent appeals to a dog.

As I mentioned earlier, eating feces is called coprophagia, which can be a direct result of a dietary deficiency. However, in most cases, eating poop is just a bad habit and is considered part of a dog’s exploratory behavior.

Health Concerns

While this habit is definitely gross, can it actually harm a dog? Unfortunately, it can. Many dogs can consume poop and they’ll be totally fine, however, eating poop carries the potential for a pet to contract harmful parasites and bacteria. Some types of bacteria they can contract can even be transmitted to humans, such as salmonella. Additionally, a dog may end up picking up several different types of internal parasites just from consuming cat poop. Just because your cat may not be displaying signs of parasites, it doesn’t mean they don’t have them. Cat litter can also be an issue if your dog eats it in large quantities.

Fortunately, most dogs will need to consume a very large amount of litter covered poop before a blockage becomes a concern. If your dog has consumed clumping cat litter or loose cat litter, you will need to keep a close eye on them. If their bowel movement is normal, then the odds are that your pet is fine. However, if your dog is having trouble pooping, their poop is abnormal, or they are unable to poop at all, then you will need to contact your vet for advice.

In most cases, a dog will not suffer any major health issues from eating the poop, however, this is still definitely a habit that you will want to get rid of.

Other Ways to Deter Your Dog from Eating Cat Poop

One of the easiest ways to prevent your dog from eating the cat’s poop is using a dog proof litter box. Another way is to place the litter box in a location in the home where the dog is not able to access it. You can put up baby gates to keep a dog out, without preventing your cat from accessing their box.
