How large an area does it cover?

The transmitter creates a circular boundary of up to a half acre. You adjust the dial to shrink or grow the circle.

Does it work for more than one dog?

Yes. Each dog needs its own receiver collar, and one system can contain unlimited pets.

The collar adjusts for necks from 6 to 28 inches and is recommended for dogs weighing 5 pounds and up.

Yes. The collar has a tone-only mode, so you can teach the boundary with the warning tone before adding correction.

Yes. It needs no buried wire, so you can move the transmitter and set up a boundary at a campsite or another yard.

It needs no trenching and sets up faster, but the boundary is a circle rather than a custom layout around your yard.
