Those olden days are gone where you put normal fences around your house and still roam around searching your dog all over the place and will still fail to succeed in finding them or very occasionally find them. Now we have a new device to overcome this problem. It is the wireless fence for dogs which is designed in such a way that it can keep track of your dog and sends you signals or alerts if your dog nears or crosses the fence. It can also easily track down the direction in which your dog has gone and also track the distance it has gone so it is easy to find your dog. This is the major advantage of wireless fence for dogs. There are different models of wireless fences available. Radial shaped fences and custom shaped fences are the varieties that are available. What is the difference between these models or varieties? When it comes to the basic functionalities, it is almost the same as it works on the same concept, however there are some additional features available in a custom shaped wireless fence. Even though the area is huge some people prefer to limit the distance and they cover it in a circle and so they can make use of this radial shaped wireless fence and others who want to fence their entire area so that they can allow their pets to wander around anywhere in their place then they can make use of custom shaped wireless fence. This is because, when it comes to covering the entire area it is more or less an irregular shape where multiple bends and turns are involved. So the distance varies in each direction and so few extra features are available in this custom shaped wireless fence to keep track of the different distances along different directions of the fence. These are different types of wireless fence for dogs that are available.
