I tried a collar like that...not quite the same, I think it was called a "mountain collar." I ony got it because it was on clearance for $1 heh.

It didn't phase Nebo in the slightest...he just choked himself.

I was tempted to try the prong collar but then most everyone on here made me feel guilty for even thinking about it.

So I tried the halti...it works great. He CAN'T pull at ALL with that. He hates it though. And I hate all the looks I get when I use it on him.
