Description

One set. Total control. Built for Bullies.

The Bullyion® MINI Trinity® Harness is made for puppies and small breeds who bring big energy to every walk. Combining trainer-trusted anti-pull technology with a lightweight, padded frame, it gives you pro-level control without compromising comfort.

With Softcell™ Padding Technology and a non-restrictive design, it protects against rubbing while allowing your dog’s natural movement. Whether you’re tackling training sessions or everyday walks, the Trinity delivers unmatched stability and confidence.

Paired with the DUPLEX Double Ended Training Lead (2m) is designed specifically for bully breeds, giving you unmatched control, versatility, and confidence on every walk.

With dual Lockforce™ metal clasps that can handle serious pull, this 2m lead adapts to any situation:

  • Structured walking and heel training – clip to multiple points for maximum control

  • Hands-free walking – wear it cross-body or around the waist

  • Two-dog walking – one lead, double the strength

  • Everyday use – comfort-padded handle sections for long walks

Built with Softcell Padding Technology, the Duplex Lead takes the strain out of handling strong breeds like Staffordshire Bull Terriers, American Bullies, AmStaffs, Cane Corsos, Mastiffs, and more.
