I need advice on getting my 6 month old pup to stop pulling on the leash. She is getting really bad about it. I'm not a very big person and she has pulled the leash right through my hand rope burning me. Any advice or ideas would be welcome. I don't know how to correct her in a way that she's going to respond to but not be scared of me or walking on the leash. She had been doing really well up until about 6 weeks ago and now she is just getting worse and worse and her first show is supposed to be the end of the month!!
