Query: Amazing Transformation

We have a 3.5 month old Brittany who is (according to her trainer) a "pistol". Teaching her to walk on the leash was easy but once she learned she pulled so hard I was sure that I was going to get one Popeye arm before she reached 6 months. I tried The Dog Whisperer slip lead training leash but that had no effect. She actually pulled so hard she was causing sore spots on my fingers! I broke down and bought the gentle leader. I was hesitant only because of the way it looks like a muzzle and so harsh on the dog (even though I know its not). I put the gentle lead on Maggie and the transformation was instant. We took our first of many walks and there was no pulling at all! Now when I walk her I actually find that the walk is a bit boring because there is really nothing for me to do - we just walk. I still wish it didn't look like it does, but I am more than willing to have the looks if the trade off is a walk without pulling! It really is amazing!!
