Dogtra CUE GEN2 (iQ FLEX) – Beginner-Friendly Remote Training Collar, 400 Yard

Dogtra CUE GEN2 (iQ FLEX) – Simple, Beginner-Friendly Training Collar

A professional training collar in a friendly, easy-to-operate design.

The Dogtra CUE GEN2 (known in Europe as the iQ FLEX) came out of real feedback from trainers: many owners feel overwhelmed operating standard professional e-collars. The CUE GEN2 was built to solve that — a simple, accessible, easy-to-use collar for beginners and older users alike, with no compromise on performance.

What sets the CUE GEN2 apart

Programmable function buttons — a trainer can preset the functions and hand the unit to a client, minimizing operating errors. A large display and oversized buttons that are easy to read and press. Nickel-free plastic contact points for dogs with sensitive skin. A safety level lock, vibration (Pager), and the category's lowest stimulation frequency for gentle, safe correction.

Who is it for?

Suited to dogs 11 lbs and up with soft to normal temperaments, and to anyone looking for a simple, friendly collar for gentle training and basic obedience. Control range up to 400 yards, waterproof to IPX9K.
