The collars 8

  1. Strap Most collar straps are leather or nylon webbing.
  2. Buckle It works like a belt buckle. The strap end passes through the frame and the tongue goes through a hole.
  3. Tongue It goes through one of the holes. That holds the collar at that size. It is also called the prong.
  4. Holes They let one collar be fastened at several sizes. A row of holes set apart along the strap.
  5. D-ring The leash clips onto it, and ID tags hang from it.
  6. ID tag Identification tags, and sometimes medical information, are fixed to a dog's collar.
  7. Quick-release buckle Two springy arms on one half click into the other half. Squeezing the arms lets them out again.
  8. Slide Moving it along the strap makes the collar larger or smaller. It is also called a slider or a tri-glide.

The leash 4

  1. Handle loop A loop for the hand. The end of the leash is doubled back on itself and fastened to make it.
  2. Webbing A flat woven strap, often nylon. It is drawn with a break because a leash is much longer than this.
  3. Swivel It lets the hook turn, which keeps the leash from twisting.
  4. Snap hook A spring-loaded clip that opens to go over the collar's D-ring. It then springs shut.

Buckle collar, snap collar, leash

Numbers 1 to 6 are on the top collar: the strap, the buckle and its tongue, the holes, the D-ring and the ID tag. Numbers 7 and 8 are on the middle collar: the quick-release buckle and the slide that sets the size. Numbers 9 to 12 are the leash: handle loop, webbing, swivel and snap hook.

  • The snap hook on the leash clips to the D-ring on the collar.
  • A buckle collar changes size hole by hole. A collar with a slide can be set anywhere along the strap.
