I am really struggling with loose leash walking with Marley, my 8 mo. old lab mix. We are doing an obedience class and they suggest doing sneak aways, meaning if Marley is not walking at my side and she starts to pull ahead that I should turn and walk the other direction and in the process Marley gets a little leash correction. The other suggestion they had was to use treats to lure Marley to my side. I have been practicing the sneak aways as well as the treats for a very long time (months; my second try at the class) and I don't feel that we have made any progress. Marley is completely oblivious to the sneak aways. She doesn't mind getting a yank on the collar and just starts pulling wildly in the new direction. As far as treats, she is interested in staying by me long enough to get the treat but goes back to her pulling right away. I even use a bridge word, "yes", when I treat her for being at my side. Does anyone have suggestions for how to get Marley to walk loosely? She is a very energetic dog. I do take her to a dog park or doggy daycare about 4 days of the week to run and we walk her several times a day as well. I also should add that I have tried a Gentle Leader headcollar and Marley will not tolerate it. I used one for about 2 months and she'd stop every couple of steps and rub her face on the ground. I have also tried the Easy Walk harness and that had no effect on her.
