The Restraints I have seen, were simple "Nylon Choker" type Collars, which were hooked on a Hook, that was adjusted to the Dog's height, when sitting or standing. This leaves one hand available to Groom, while the other hand supports the buttocks, when standing on all four is required.

When adjusted properly, the length/height of this "system" prevents a Dog from moving anywhere near the edge of the Table, and actually keeps it from laying down as well. Possibly a little restrictive/uncomfortable for the Dog, but, it's quite temporary and acceptable to me, under those circumstances, except for the Choker Collar.

Apparently, this system was not used, and a Leash of sufficient length was, where the Dog could access the side of the Table, and jump.

This presents an issue of negligence from the lack of attendance, and possibly the choice of Equipment selected by the Groomer, could be related to intent as well (I certainly would).

Gives us all pause, and concern where it wold be a very good idea to personally inspect any facility groom/board/whatever, prior to leaving one of our animals in their care, custody and control.
