Our buckle collar is your standard adjustable buckle collar. It offers the best fit possible with holes every 1/2 inch along the collar. They are E-collar compatible with Mini and Micro Educator systems, as well as many other brands. For an excellent fit and superior comfort, add a bungee to your collar.
If using with an ecollar, please check with your e-collar manufacturer for necessary width. We are not responsible for incorrect information, nor refunds due to incorrect width being ordered.
If the collar is to be used with an E-collar, please let us know by checking the box so that we can accommodate length for the receiver. We are not responsible for incorrect/missing information. 
For best fit please include your dog’s neck measurement in inches in the comment box. If no measurement is included, a standard size fitting 13"-18" will be ordered. We are not responsible for incorrect measurements.
