The Dogtra Smart Fence is a portable, no-dig wireless containment system built around a 2.4 GHz Control Station that creates a circular RF boundary radiating out from a mounted central point — covering up to 3/4 acre with no buried wire, no GPS, and no monthly subscription. When the collar-wearing dog approaches the boundary, the system steps through tone, vibration, and static stimulation across 24 correction levels. If the boundary is crossed, the 2-tier alarm fires: an 85-decibel audible alarm on the Control Station and an app alert when your phone is within Bluetooth range. The collar works independently after initial setup — no phone required to keep the boundary active. IPX9K waterproof, 2-hour rapid charge on both the Control Station and collar receiver, pairs up to 2 dogs, and designed for outdoor use at home, at the cabin, or in the field. No digging. No fees. Professional-grade Dogtra construction.
