Partial wire breaks can be a long term problem if you don't use the proper connections and splices. The most common types of wire breaks result from improperly sealed splices. Over time, rust and corrosion compromise the splices and cause your dog fence to malfunction.

Before you begin splicing wire, it will be helpful to you to take note the locations of all splices for future reference. If you ever have a wire break, these most often happen at a splice and it will be helpful to you to be able to find your splices easily if this ever happens.
