Things You'll Need
- Fabric tape measure
- Chain link
- One eyelet ring, 1-1/2 inches in diameter
- One eyelet ring, 2 inches in diameter
- Needle-nose pliers
Instructions
Measure your dog's neck, high up near his head and not lower near his shoulders. Add 2 inches to the figure and write it down. Go to your local home improvement or hardware store and purchase smooth chain link with 1/2-inch dull links. Purchase the length you need from the measurement you took of your dog's neck.
Cut the chain link to match the measurement of your dog's neck. Use a pair of needle-nose pliers to open two eyelet rings and attach one to each end of the chain link. Attach the 1-1/2-inch diameter eyelet ring to the left end of the chain and the 2-inch diameter ring to the right end of the chain so that the larger ring can slide over the smaller one when you slip the collar around your dog's neck.
Test the fit to ensure it's not too tight by sliding the collar over your dog's head so that both eyelet rings are above and not below the dog's neck. Attach your leash to the left eyelet, understanding that when you pull on the chain, the collar will shorten slightly around the dog's neck, making the collar a bit uncomfortable and thus training the dog to heed whatever command you have issued at the moment you tugged on the chain collar.
