An electronic dog fence is a useful addition to any home where dogs tend to stray. When searching for an electronic dog fence, keep in mind that these systems go by many different names. Some of the more common names that you may want to search for are: Electric Dog Fences, Pet Containment Systems, Pet Fences, Underground Fences, Electric Pet Fences Regardless of the name they go by, they have one thing in common. These are fences designed to use radio waves along with a collar worn by the dog to deter your pet from crossing their boundaries.
If you have several dogs that you need to contain, you can purchase electronic dog fences that service all the dogs. Each dog will need to have its own collar, but you will only need the one boundary system to control them all.
It is important to know that electronic dog fences are designed for dogs that are over six months old. These fences are not calibrated for pups younger than six months, who may react badly to the effects of the deterrent.
There are many advantages to having an electronic dog fence. Compared to rail and post fences, they are much more affordable. An electronic dog fence is something you can install yourself, so you can save a lot of money on installation costs. An electronic dog fence cannot be jumped over or dug under by your dog. Termites cannot eat through them, and lawn care is much easier with an electronic dog fence than with standard wooden fences.
In addition, there are some neighborhoods or condo associations that will not allow the construction of a regular wooden fence. In cases such as these, an 
electronic dog fence is perfect, for there are no unsightly posts or rails.
The normal maintenance for an electronic dog fence consists of changing the batteries periodically.
Some people may feel that an electronic dog fence is cruel to the dog but that is not the case. In general, the fence works like this: if the dog approaches the boundary line, a warning tone sounds to alert the dog. If he continues toward the line, a small electronic correction is delivered. If the dog still continues toward the line, a larger correction is delivered. Many kits contain warning flags as well. These are very useful in teaching your dog where the boundary is. Using warning flags, it usually takes about two or three weeks to teach him how far he can go.
If you and your dog travel a lot, you can purchase a portable electronic dog fence. These are perfect for pet owners on the go. Instead of using wire, they use a radio frequency to alert your dog that he is getting too close to the boundary line.
One thing to keep in mind is the size of your dog. If you have a large dog or one who has an especially mean temperament, you should not rely solely on an electronic dog fence for containment.
