Now let’s get into my favorite system. Hands down from ease of installation to maintenance to portability, the Petsafe PIF-300 wireless instant dog fence is the way to go.
This product operates by transmitting a RF signal that the collar must be able to detect. If it doesn’t, it knows that it’s too far away from the base station and starts correcting the dog until they get back within range. There is plenty of safety circuitry in place to keep your dog safe in the event of power outage or accidental unplugging.
The signal is a circle around the base station, obviously, and can be adjusted out to about a 180′ diameter circle. Of course obstacles ,walls, buildings, and so on do affect the range and the pattern, but over all it’s quite predictable.
The best part is that there’s no wire to maintain, and your dog can’t run through anything since it’s RF-based. And when you move, grab the base station and set it up at your next house. Problem solved.
