Finally, the first Dogtra expandable system is available. Dogtra EDGE is a fully customizable and expandable e-collar (up to 4 dogs) designed for professional and serious amateurs. Dogtra's EDGE collars now have a superbright LED locating light built right into the collar. Select Red, White, Green or Blue you want to use to identify each dog. Collars and the Transmitter are 100% Submersible & Waterproof!

Dogtra EDGE is easier to adjust the intensity levels to suit each dog. The EDGE now offers the Rheostat Mode with 127 progressive intensity levels, or a User-Selectable Intensity Mode with 8 Preset Stimulation settings.
