Grooming nooses can be ordered from a number of places see link below But you need a grooming table with a grooming arm(usually comes with noose) to use them. It is much easier to groom a dog on a table than other places because they are out of their preferred element they tend to not like heights and well stay still for you and it is much easier on you as well.
You should also be able to find a table with arm at Petsmart but they will be higher priced than Petedge..
