EZ-903 Easy Educator – 1/2 Mile 3-Dog Remote Training System

The EZ-903 Easy Educator is a 3-dog remote training system designed for intuitive use, safety, and humane effectiveness. Based on the EZ-900 platform, this remote it’s fully expandable to a 4-dog system with the addition of a fourth collar receiver. Each collar comes with a color-coordinated strap that matches its corresponding button on the handheld remote, making it easy to manage multiple dogs with confidence and clarity during training sessions.

This dual-dog system offers 100 levels of “blunt” stimulation per dog, along with a customizable boost (1–60) and COS (Control of Stimulation) technology for smooth, humane correction. You can tailor the experience to each dog’s temperament—ideal for households with dogs of different sizes or sensitivities.

Non-stimulation alternatives include 7 advanced vibration modes and 4 tone options, perfect for dogs that respond better to gentler cues. These advanced features are fully customizable using the included computer interface tool.

The compact, 2.4 oz receiver is lightweight enough for small dogs but strong enough to handle large, high-drive breeds. A built-in night tracking light (solid or flashing) on each receiver enhances safety and visibility in low-light settings. Fast-charging lithium polymer batteries power the system, giving you extended use with just a 2-hour charge.

Brian B. ★★★★★

The buttons are laid out so well that I can switch between my three dogs mid-walk without even looking down, and the half-mile range holds up even through our local park's treeline. Setup took me maybe five minutes per collar, which was a relief since I'm not exactly tech-savvy.

Kevin ★★★★★

I’ve used it with all three dogs at the park and the 1/2 mile range held up even with trees between us. The transmitter feels solid in hand, and switching between dogs is quick enough that I don’t lose focus on training.

Isabella N. ★★★★★

The half-mile range gave me real peace of mind when our escape artist pup bolted into the field, and the receiver's vibration level was enough to get her attention without any shock. Toggling between all three dogs on the remote is simple enough that my partner figured it out in under a minute.
