Dog Chain Slip Collar
Accurately measure your dogs neck. The chain collar should be three inches longer than your dog's neck measurement. If your dog's head is slightly wider than its neck, then size up.
For proper use, slide the chain through one of the metal rings. While facing your dog, form the collar into the shape of a P. Slide the collar carefully over the dog's head. Attach a leash and you are ready to walk your dog.
BOTH dog models are wearing size 20 in.
