I’m a big fan of martingale collars. For anyone who isn’t familiar with them, they are most often used on greyhounds and work sort of like a choke collar but made of material instead of metal. If your dog’s neck and head are virtually the same diameter, like a greyhound, instead of them slipping out of their collar the martingale will tighten up and keep them safely on their leash. Anyway, even if you prefer a more traditional buckle-style collar, 2 Hounds Design makes beautiful custom collars in the size, style, width and material you choose. Neat, huh? My own dog, Dottie, loves them and looks quite pretty in them. 
Their website is http://www.2houndsdesign.com/ if you want to take a peek – happy shopping!
