Some people want to allow their dogs to run freely outside without the fear of them leaving the property, but also cannot or do not want to put up a fence. For those people, there are dog gates available that are similar to fences, but not in the traditional sense. These gates are more like metal pens that provide a “run” or small play area for the dog. Depending on the style, these dog gates can be permanently installed or can be collapsed and stored. These types of dog gates are popular with people who show their dogs, so that the dog does not need to remain in a crate while at a show. For other people who have a dog in a community that has little outside space, or shared outside space (townhouses, apartments, etc.), this might be a good option, because it has the flexibility of being temporary.
