DOGzwear Limited Slip Collars are easy to put on and take off. No buckles to deal with, just slip on the collar, make a one time size adjustment and its easy on and easy off.
The limited slip collar is NOT a choke collar. The collar is meant to fit loosely while there is no tension on the collar, and slid closed when there is tension. You need to make the size adjustment so when the collar is at it's tightest it still fits comfortably on your dog. You should be able to get one or two fingers under the collar when it is at it's tightest.
Adjustable from 11-18 inches
