Our Tactical Deployment Collar is made from 2 layers of of our Premium Leather. Suitable for restrained bite work and agitation. It is 2 inches wide so that the pressure on the dogs neck is kept very low. Two ply leather means it is made from two layers of leather stitched and riveted together. There are loads of this type of collar available but we found that the control handle is always near the buckle, and this means that the handle ends up under the dogs neck. This redesign we have come up with has the buckle opposite the handle, so the buckle sits under the dogs chin, keeping the handle up high where you can grab it. We have also added a leash connector snap under the handle so if you have your leash hooked to this collar, again the handle is kept up the top. The handle is used to control the dogs head in deployment, a must for Police Service Dogs, Military Working Dogs, Correctional Services dogs and Personal Protection dogs working in a populated environment. Premium Leather, 277 Commercial Stitching, solid hardware. Stop looking for a stronger collar, there isnt one.
