Our agility club recommends and sells Gentle Leader Head Collars and Gentle Walker Harnesses.
The harness is recommended where dogs dislocate your shoulder on casual walks, or is inclined to bolt if anything attracts its attention, whilst the head collar is used where dogs don't pull hard but don't respond to a call or pull on a normal collar and do not bolt at distractions.
If a dog is a bolter, the head collar could cause injuries to the neck when it comes to the end of the leash. Well actually, its not the leash that causes the injury, its the sudden stop.
