It seems that animal companions might also benefit from the technological evolution. The GPS (Global Positioning System) system represents the latest association of high-class technology with pets. As a result of this invention, we might never see those "lost dog...we offer reward" posters on poles.

In the United States and France, there are already satellite positioning systems for animals. These systems are based on the same principle as the ones for cars.

In California, the GPF (Global Pet Finder) system is available for $350 plus subscription fees. The GPS emitter-receiver is installed on the pet's collar and is powered by rechargeable batteries. The system has several functioning modes: one can establish the area where the pet may roam freely, and if it steps out of that area, the GPS will instantaneously announce the owner through a cell phone, PDA or notebook message, giving its location with only a few meters error margin. You will be displayed a map indicating its location, and if you go for a walk, you can deactivate the system, and reactivate it if your dog disappears.

In France, Trave Dog offers a similar service, which costs around 300 Euros plus 15 dollars monthly fee. The emitting, rechargeable collar announces the owner if the dog has disappeared, and through the cell phone he/she will have access to a map indicating the position of the missing dog.
