A Haltie and GL are basicly the same thing, the only difference is design, the Halti has a little peice that attaches the nose and head part on either side, while the GL does not. I prefer Halti because of that, without those attachment straps my dogs can remove the GL in 2 seconds flat, while the Halti take some work for them to get it off.

and glad it worked critter crazy! I know the feeling, before I got one, I had given up on Misty, I tried evrery trick in the book to get her to stop pulling, but while they all seemed to work at first, eventually they all just made her pull even MORE lol
