An animal training device for use with a head collar, a neck collar and a
leash simultaneously includes: an elastic body removably coupled between
the neck collar and the leash, the elastic body lengthening in response a
separating force between the neck collar and the leash and an inelastic
line removably coupled between a snout portion of the head collar and the
leash, the inelastic line having a fixed length. When the animal pulls
against the leash, the inelastic line exerts a force on the snout portion
of the head collar.
