I am so glad all my dogs have quick release collars. Yesterday Alex and Suzy were "horsing around" As usual Suzy was bullying him and grabbing his collar - well she got it all twisted and I'm on the phone long distance with my mother I hear this yelping, see her mouth all twisted up in the collar, throw the phone down and grabbed the collar's quick release. She was shaken up and I think this may have cured her from doing it again. I think she may have lost a tooth or even strangeld Alex had I a) not been there b) not had a quick release collar. Just an FYI for how great these things are.
