I don't know whether its the colour that makes it look bigger than it actually is or what? but it just looks too big if you ask me. I personally would of had something a bit smaller, and a darker colour but either way you've got yourself a collar that is gonna last you a life time mate.
You get what you ask for with SS though, and as I said earlier his dog clobber is top notch.
You've got a mint looking dog though mate, best of luck with him.
