ナイロンプロングキャッチ

The backup loop is a simple concept but it's executed really well here, and the nylon feels sturdy enough to trust with my dog's safety. It took me less than a minute to clip it onto the bolt snap and his flat collar, and now I don't have to worry about a failed prong collar leaving him loose.

I was nervous about using a prong collar without a backup, but this catch solves that completely — it clips onto both the bolt snap and my flat collar, so even if the prong fails, the leash stays connected. Set it up in under a minute and it hasn't budged on our daily walks.

The nylon material feels sturdy enough to trust with my dog's safety, and it clips on cleanly to the bolt snap without any fiddling. I've tested it on a few walks and the leash stays put even when he lunges after a squirrel. This is the kind of backup piece I wish I'd bought months ago.
