Marley again!

This summer has been so hot that we have not been able to take Marley.......I mean Summy on her long walks. Well with it starting to cool down we decided to get her out on her walks again. I though that maybe now since she is 3 1/2 and had a lazy summer that she would possibly calm down a bit. Yeah right! We went on our first walk Wednesday morning and she about killed me with all her pulling. I was so sore (more sore than I am from running) on Thursday that I had to take a day off. Today I decided we would give it a try again and yes she pulled the heck out of me again. I have to stop and make her sit everytime another dog comes down the trail because she goes so crazy. The one time I stopped and kneeled down in front of her while a dog came by and she still went crazy knocking me down and dragging me until my knee was bleeding from being skinned up so bad. The lady walking the other dog kept appologizing and I'm thinking she probably thinks I have the craziest dog in the world, which isn't far from the truth! So we are starting all over with our crazy dog and hopefully can get her being halfway normal again for these walks. We shall see. Anyone having any good tips on controlling a 100lb crazy lab I would love to hear them!
