When crate training one of the most important parts of the process in deciding to crate train is not only the method by which you decide to train but the size of the crate as well. It makes sense that if you have a large breed of dog you are going to need a large dog crate as well. Your dog needs to have adequate space to make his or her crate equal to a den or home instead of seeing it as a trap or uncomfortable cage that they are placed into often.
Obviously, a large dog crate is going to cost a bit more than a small dog crate because of the material differences. There are crates that serve different purposes. Some are meant to be used inside on a daily basis to be left in one location while others are used for traveling both in cars and on airplanes as well. The crate material is highly dependent upon the functionality of it. 
Wire and plastic can both be used in the home while for traveling it is recommended to use plastic. You can find a dog crate at a pet store or even in a variety of hardware stores. If you’re looking to save some money you may also look in the newspaper for people selling ones that they no longer need. A medium to large dog crate will cost you approximately $50-$125 for one of good quality.
When deciding what size of crate to buy, you may look into getting one that can have a divider because it will be very costly to buy a new crate every time your dog gets bigger. This will aid you in training and saving financially.
