The Download: SpotOn virtual fence

Training a dog to stay in your yard can be challenging.
A fence around your property can keep pets in, but some people don't like the look of them. That's where the SpotOn virtual fence can come in handy.
The invisible fence uses GPS technology to map out an area that your dog needs to stay in. After a little training, your dog can roam the area and the collar will give audio alerts when its getting too close to the boundary.
The virtual fence is highly portable, that means you can take it on trips, like to the beach or camping. You just map out a new boundary and then you can feel confident your pet will stay close. If it does leave the area, the collar has an optional tracking service that can immediately alert your smartphone.
The SpotOn system is $1,500 and comes with a year of free tracking.
