How does the collar respond when a dog pulls?

What collar size should I choose?

Choose by the indicated neck size, not by the collar’s overall length: this version is 25 in (63.5 cm) long and fits neck sizes up to 21–22 in (53.3–55.9 cm). If adjustment is needed, remove or add pronged links to set the collar length. Compare your dog’s neck measurement with the stated neck-size range when selecting this size.

• Collar thickness: 4.0 mm.
• Adjust the fit by removing or adding pronged links.

How does the ClickLock buckle work?

The ClickLock buckle allows easy placement and removal of the collar. An O-ring and a U.S.-made Biothane insert provide stability and security at the buckle connection with the prongs. The black plastic jacket slides onto and off the unfastened buckle; it does not interfere with the buckle enclosure’s functionality.

• The buckle connection includes an O-ring and Biothane insert.
• The black plastic jacket is removable from the unfastened buckle.
