Trying to figure out what size or style of dog crate to buy? This may seem like a simple question with a straightforward answer, but figuring out the right crate for your pooch actually depends on a few different factors, including the purpose of the crate, whether your dog is a puppy and (of course) your dog's size.
The Right Dog Crate Depends on Its Purpose

The answer to "What size crate should I get for my dog?" depends largely on how you intend to use the crate: Do you want to take your dog with you on a trip, train them not to do their business inside, or crate train them? Here's advice for choosing a crate for any occasion:
- Potty training: If you want to use a crate to housebreak your dog, it should be large enough that they can stand, sit up and turn around without hitting the sides. But it should also be small enough that if they relieve themselves in the crate, they'll soil their sleeping area, says Labrador Training HQ. Dogs have a natural instinct to not have their bathroom and their bedroom too close together. This is what helps them understand that if they want to do their business, they need to do so when they are let outside.
- Air travel: Airlines that allow pets usually have their own crate requirements, says the International Air Transport Association. You'll want to look for a crate that meets the airline's conditions but still allows your dog enough room to be comfortable.
- Car travel: While it might seem less fun, car travel is safer for your pooch if they're secured with either a harness or crate. In addition to making sure the crate fits the area where your dog will be riding — the backseat is preferable — it should also be small enough that your dog won't get tossed around inside of it in the event of an accident or a sudden stop. At the same time, it should be large enough that they're comfortable.
- Containment: If you're going to crate train your dog while they're home alone, opt for a slightly roomier crate that gives them room to stretch out, stand and sit, and that will also fit a toy or two. While it may seem kinder to get the largest crate you can find, keep in mind that dogs are den animals who find security in tighter spaces, says Labrador Training HQ. A crate that's too roomy is more likely to make your dog anxious than one that's just their size. Assuming your pup is potty trained, they may need extra space to relieve themselves on a pee pad.
What Is the Right Size Crate for My Dog?
Of course, the biggest consideration when choosing a crate is the size of your dog. If possible, it's best to take your dog with you to the store so they can try it out. But if you need to pick out a crate unaccompanied by your pooch, here are general sizing guidelines, courtesy of Labrador Training HQ.
