This upgrade will convert your collar order to a martingale (chain or fabric versions). This is NOT a collar listing, you must add a collar to your cart separately to apply this upgrade.
HOW TO CHOOSE BUCKLE TYPE:
If you choose a buckle martingale, the buckle will be plastic or metal based on the choice on the collar listing you are upgrading. For example, to order a 1" width fabric martingale with a silver metal buckle, the collar for the upgrade must say "1"/Metal/Silver" and this upgrade should say "Buckle/Fabric Martingale".
Please read on the function and purpose of martingale collars before buying. These are good for dogs that might try to slip out of a collar, but as they do tighten down when a dog pulls, you should be aware of the proper and safe use.
