Many groomers use what is called a "loop". It is not tight around their neck. Some groomers do not use a loop but most of the one's I know do. As long as they do not walk off and leave your little one on the table with the loop then it should be fine. I have heard horror stories of a local groomer leaving dogs on the grooming table with the loop only to be found out by owners who have walked in to pick up their dog.
