Ok here's the deal - I have been trying for ages to straighten out this problem and I think I mentioned it in one of the food aggression posts, but well Bonnie still pulls. In about 2 weeks, she will be 8 months old and she still pulls. Not nearly as much as when she was younger but she still does it and I need it to stop. I have had to put her on a choke chain, and every time she pulls, I give it a jerk and stop. Then when she's good, I start again. I saw this in a book, and it has helped, but not as quickly as it should. I have been trying this method on her since I was sure her neck could handle the chain, (about 4 months). It's only a little tight (the lead) when it's just me and her, but when Lou is with us it's unbearable. It's actually embarrassing to walk her with Lou, she hacks and strains and her eyes bulge. I have tried the short leash but she just doesn't get it. The other day I felt terrible, she gave me a look that said why are you hurting me? and I felt sick. When we're on our own, it's bearable until we meet someone else walking along the street and then she jumps and strains. If she doesn't do that, she crawls along the ground (especially if there's another dog). Any hints?
