It just barely touches him and I love turtlenecks, lol! I give him a treat every morning when I put it on him so he's happy to put it on. I take it off at night.I couldn't bring myself to use those because of the collar having to be tight around the neck and those 2 prongs sticking into their necks. I cant stand turtle neck sweaters or anything touching my neck and cant stand to see it on others.
