Abstract: A univeral animal grooming post is provided which accommodates animals of varying sizes without the necessity for adjusting the mounting of the post on a grooming table. The universal grooming post includes a hollow upright stanchion and a hollow arm projecting laterally therefrom. A tether is provided which includes an inelastic portion protruding from the laterally projecting arm and an elastic portion coupled thereto that is secured within the stanchion. A locking mechanism allows a selected length of the inelastic portion of the tether to extend from the arm. A greater length of the inelastic portion of the tether extends from the arm to accommodate small animals, while the locking mechanism is adjusted to allow a much shorter length of the inelastic portion of the tether to extend from the arm to accommodate animals of larger size.
