Ludus 5.0 harness – Next-generation dog harness for pulling
The LUDUS 5.0 harness is designed for constant pulling situations in single-dog setups, where effort is sustained and repeated over time. Built for disciplines involving engaged pulling, it follows the dog’s movement throughout the effort, ensuring efficient forcee transmission without restricting joint mobility. Its design is based on a precise structure that frees key areas involved in pulling, including the shoulders, shoulder blades, back and hidquarters. This architecture supports smooth and stable propulsion, especially during running phases when the dog fully engages its stride.
The Ludus 5.0 harness is intended for activities such as canicross, bikejoring, dog scootering, skijoring or hiking with constant pulling. Its ergonomic design is suited to lupoïd, graïoid and braccoid morphologies, respecting joint range of motion and natural movement.

Why choose a dog harness for pulling ?
In activities involving constant pulling, the harness plays a key role in force transmission.
A pulling dog harness must distribute pulling forces efficiently, preserve freedom of movement and support propulsion without creating constraints on the shoulders, back or hindquarters.
A well-designed harness improves pulling efficiency while ensuring comfort during prolonged effort.
What makes the Ludus 5.0 harness different
The Ludus 5.0 harness is built on a structure specifically designed for constant pulling. Its V-shaped neck and controlled angle opening concentrate pulling forces toward the shoulders and chest, ensuring direct and efficient force transmission. The O-back structure frees the dog’s back during the stride regrouping phase, which is a key moment in propulsion.
This combination ensures smooth, stable and consistent pulling throughout the effort.
What is the Ludus 5.0 harness suitable for ?
The Ludus 5.0 harness is designed for disciplines involving constant pulling. It is particularly suitable for canicross, bikejoring, dog scootering, skijoring, mushing and hiking with sustained pulling.
Designed for lupoïd, graïoid and braccoid morphologies, its ergonomic construction respects chest volume and fully preserves joint mobility and natural movement.

Technical features
V-shaped neck and force orientation
The V-shaped neck and controlled angle opening direct and concentrate pulling forces toward the shoulders and chest.
O-back structure
The O-back construction frees the dog’s back during the stride regrouping phase, preventing any dorsal compression.
Rear adjustment and long attachment point
The rear adjustment allows precise fitting based on the dog’s size and morphology. Combined with a long attachment point, it ensures consistent positioning under pulling.
