You're right, I do see a difference! They're definitely much sharper.
I love that!
Chains work well I think. We've had Zoey's chain for a while and it seems to be good for her. She's able to go all the way in the front yard as you know haha. But yeah..sometimes once in a while she'll get caught on something, but other than that it works well.
That's what my Dad was worried about, it would get caught around his leg or something and he'd be like "BUT ITS A RABBIT" and hurt himself by pulling to hard. Our old dog got our cousins dog tangled into a mess like that, so he's kinda paranoid, but rightfully so at the same time. I have to say though, chain seems like a better idea than rope, much stronger. It'll prolly come down to how much it costs, I need to look into it. :p Long message!! haha. Thanks. :)
