Canine Equipment Technika 1-Inch Webbing Martingale Dog Collar, Medium, Blue

My Doberman has a relatively small head, and when she pulled back she sometimes could get an ear -or her whole head -out of the standard collars we used. This one is great and she's never slipped it. Plus, it has a separate D-ring for a leash (the other one is for the ID and license tags), which is very handy.

best nylon, so strong and sooooo soft, really keeps pups from slipping out of collar and much more gentle than horrible choke collars, safer too. however the 3/4 inch is a better choice for small to medium breeds.
