The term ‘dog crates’, is sometimes used by some people to mean dog houses or kennels. To dog and pet store owners, the term refers to a small portable cage mainly used to transport dogs and animals from one place to another. Crates are usually small, in order to make it easier to move it around, but they must be big enough to allow the dog to stand and turn around inside the cage. There are many different types of crates built with different materials. They all have different purposes which you need to know about before you decide to use one.
Why do people use dog crates? There are many reasons for using them. The most common one is transportation. They are more portable than kennels and dog houses and are therefore very convenient for pet owners who love to move around with their pets. Just like the crates used to move wild animals, they are designed to be only large enough to allow portability. Most of them are very well ventilated and allow the pet to see what is happening outside, which is psychologically necessary for some dogs.

When traveling, there are times when you need to find a way to restrain the dog. Some dogs would prefer to be contained in an enclosed area. When you leave the dog in your hotel room, the crate is a convenient place to keep the dog until you return.
When traveling by air, airlines require pets to remain in the crate. There are crate models that are approved for this purpose by the airline, so you need to look out for that when shopping.
Another reason why people use crates is to train the dogs. Most kennels are made of wood. Some dogs develop a habit of chewing on the wood. This could be an indication of some kind of psychological frustration. To avoid this, the dog is placed in a cage or crate. The crate should of course be made of other materials other than wood. You should look for an aluminum or wire crate. If kept in the cage long enough, the dog can break the chewing habit.

If you have small dog a crate will keep it safe, during parties and other events such as family gatherings during thanksgiving. Crates prevent people from stepping on the dog as they move up and down the house. Pets tend to rest on the most inconvenient of places. Like just next to the couch or in front of a door.
