How Pet Containment Fences Work | Best Pick Reports

Collar.  Most systems operate by emitting a series of beeps or vibrations as a warning if the pet gets too close to the boundary. If these beeps are ignored, the animal receives a correction akin to a static electricity shock. A variety of collars exists on the market—correction settings and signal range vary from company to company. Collars are offered in a range of sizes and should fit snugly on the animal’s neck to ensure that it can’t be removed by accident. While the battery life of the collars is not a concern, it should be monitored; when the juice runs out, so does the capacity for containment.

Wire.  Buried underground around the perimeter of the containment area, the wire acts as a conduit for the transmission. The wire still works if it isn’t buried, but installing it underground helps protect it from lawnmowers, garden shears, etc.

Transmitter.  The transmitter functions by emitting a radio signal along the wire, and the receiver collar picks up the signal. Some systems work in reverse, where a predetermined range is set from a wireless transmitter. When the dog exits the zone, it receives a correction.
