A dog cage is essentially a dogs own room, its own area in the house that is completely his own. Choosing the right dog cage is an important decision that requires some thought. The ideal dog cage should be tall enough for your dog to sit or stand upright and long enough so they can stretch out while on their side. If the cage is too big and your dog has too much room he might soil one end. Dogs, like most animals, don't like to be around their waste and it will cause them feel uncomfortable. If the cage is too small the dog can't move around and will again feel uncomfortable.
A wire dog cage is usually your best option, it provides ample air holes and allows the dog to easily see his surroundings. If your dog has a barking problem when he is left in his dog cage then a cage cover may be necessary. You can either buy one of simply use a towel over the top. Also make sure your dog cage comes with a removable plastic tray, which allows for easy clean up.
If you are raising a puppy feel free to buy a cage based on his full grown size. There are dividers that can either be bought or they often come with the dog cage. Again allowing for enough room for your dog to stretch out on the floor and sit or stand upright in the cage, move the divider back as your dog ages, eventually utilizing the entire space.
When trying to decide where to put your dog cage the kitchen is usually a good place. Dogs enjoy to be around people so putting them around a lot of foot traffic will allow them to become comfortable in their cage knowing you are not far off. Often times, especially with puppies, dogs will bark at night in their cage. This is because they are either lonely and crave your attention or they have to go to the bathroom. Putting an additional cage or just having one in your bedroom is a good thing to do because it allows them to be near you all night and let you know when they have to use the bathroom.
