Level 4: X Line
Protection redefined to the highest sophistication: A Two-Dog Team trained to operate at levels never seen before.
The summit of Personal Protection
2 Dogs that move as 1 – X Line is the ultimate revolution in canine Protection. Our Two-Dog Teams are trained to operate with seamless coordination and unmatched precision. Developed exclusively by AlpinHaus, X Line offers a security solution for those who want nothing left to chance. These Dogs are not only the most sophisticated protection assets available but also the most rare and intensely developed Protection companions available on earth.
How X Line Works
Two Dogs from the same litter are trained together from puppyhood, forging a natural bond and synchronized command response. Both undergo the full progression through Levels I to III, but are also trained to operate as a coordinated defense unit. They are fluent in dynamic maneuvers, attack and recall on command, and threat response both as individuals and as a team that moves as one.
This system ensures one Dog can always back up the other—even if one is momentarily disabled or distracted. X Line neutralizes the “What If?” in high-stakes security, and ensures that a threat will be neautralized.

Exclusivity & Availability
X Line Dogs are the most exclusive offering in the universe of Protection canines. They have no equal and no one else, anywhere, will ever be able to create them. The siblings, raised together from birth, are bonded through constantly rigorous, precise, real-world training that spans 16-24 months.
While there have been other trainers who have attempted to train 2 Dog teams, these Dogs are far less sophisticated and effective that X Line.
Other Dogs almost always have to be deployed in sequence, one after the other. They do not have the control that X Line Dogs do, either before, during or after the deployment. As a result, as is always the case with Protection Dogs, neither the situation nor the Owner/Handler is in control. And in fact, because there are 2 Dogs, it is more out of control than it would be with just 1.
X Line Dogs have all of the control that our single Dogs have, at all stages. They operate as one and move as one. They can be trained to defend against multiple attackers as well as to “lock down” a residence in the event of a suspected break in. They of course work as independent Protection Dogs in their own right and, as is the case with all of our Dogs, can be managed by children if necessary.
In short, X Line Dogs are the most sophisticated Personal and Family Protection Dogs in human history.
