This is a specialized, heavy-duty collar used in police and protection dog training (often during agitation or bite work) to safely control and restrain the dog during high-drive exercises. Sometimes it is also referred to as a protection collar or working dog collar in professional contexts.
Extra reinforced, specially sewn agitation collars in double leather. 5 cm wide with padding. If a harness is not used, it is important to use a wide and strong collar that distributes the pressure. These agitation collars can withstand a dog that pulls. The collar must be secure so that the dog cannot get loose, perhaps at a moment when the decoy is without a protective sleeve.
