The adjustable team collar has no buckle or holes.  It has an adjustable slide to suit different head sizes. Once the collar is slipped over the dogs head you adjust to a comfortable fit. 

With no buckles to give or break, and designed to be slipped over the head, these collars can endure tough pulling. Stronger than leather or chain collars and minimizes wear on your dog's coat. Very popular with Siberian Husky and Alaskan Malamutes due to the strength and durability of the collar.
