Dogtra 4503 EDGE | 3-Dog Set Expandable 1600m

Dogtra 4503 EDGE — Train 3 Dogs with an Expandable System

The Dogtra 4503 EDGE is the 3-dog version of the versatile EDGE system, designed for professional trainers and owners with multiple dogs. With a range of up to 1600 metres, you train all three dogs simultaneously with the same transmitter, with the option to expand later to 4 dogs.

Interchangeable control dial

The handheld transmitter has an ergonomic tube shape for effortless one-handed operation, with an interchangeable stimulation dial: choose between a smooth Rheostat dial for fine-tuning, or a clicking Selector dial with fixed steps for consistent, repeatable corrections.

Powerful, versatile correction

Choose per dog between continuous stimulation, short pulse (Nick), or non-stimulating vibration (Pager), each adjustable across 127 levels. Designed for highly driven dogs from 15 kg.

Visible in the dark

Each receiver has a built-in locate light that keeps all three dogs visible during night training, easily activated from the transmitter.

Each dog gets its own channel

Each dog gets its own channel, its own stimulation level, and a colour-coded collar matching a button on the transmitter and the backlit LCD screen — ideal for professional trainers working with multiple dogs at once.

Rugged and waterproof

All three receivers are fully waterproof (IPX9K), with replaceable fast-charge batteries (2 hours) and extendable contact points for dogs with thick or long coats.
