When i read this it made me think of Daisy. On some walks we take she is constantly pulling the leash tight, then turns when she feels the tug, slows down, lags behind, speeds up, hits the end of the leash, rinse and repeat. I found that at times, we walk too slow for her. So she started pulling so i sped up, she went faster, i sped up, she went faster, im jogging, she is trotting, im running, she is keeping up, I'm sprinting, she is sprinting. At that point I lasted about a min or two(out of shape

) then we stopped to wait for mom and our pug ozzy. I was laughing my backside off, huffing and puffing and Daisy was more excited then I have ever seen her licking me and dancing around. So make sure you watch your dogs speed as you go, you might be going to slow even though your bully looks like a rock with legs. On a side note, i think i have a jogging buddy.
