I suppose I'm a bit paranoid (especially about my dogs) but I think I would be afraid to use one on my dogs. If they should get away and get the collar hung up (on a fence, a gate, a tree, etc) they would never be able to break free with a paracord collar. An ordinary collar worries me enough as I remember one of Daddy's bird dogs strangling himself like that when I was a small kid (pre-school)
