I was wondering what opinions people have on how secure their dog leads are. A week or so ago when out walking my dog in our our street, the spring part of the clasp failed, allowing the clasp to fall open (its default position with no wire/broken wire spring it), disconnecting the lead from our dog's harness. We were lucky, as our dog didn't realise it had happened and just carried on plodding along, and the street we were in is usually quiet (not too much traffic). The only signal I got that this had happened was that the lead suddenly went slack, on looking down I saw it had disconnected and held on to our dog whilst we got a spare lead. To try and illustrate the type of clasp, see this at Amazon. The internal wire spring failed meaning the clasp hinge was loose and flappy and therefore useless (this isn't our lead, just an illustration). Obviously you can also get leads with this type of clasp - is this any more secure? If the internal spring fails I would imagine it's also likely to disconnect from harness or collar. I've seen leads with carabiners and I guess whilst not as easy to detach and reattach, if the carabiner itself is of good quality metal, this looks more secure. I'd be interested in any thought or reports from your own experience. Thank you!
