I,ve been grooming for 22 years and have never used any kind of restraints. I,ve taught at the London Academy of Grooming and have seen a lot of dogs trying to hang themselves fighting againt restraints that were to tight, I tried to teach the students how to handle the dogs rather than cause the dog stress by restaints, what ever kind they chose, resticting free movement. Staying calm while grooming would be he best grooming tool you will ever need, let the dog want to stay on the table for you.
