what kind of dog is kentucky? halti leads / gentle leaders work great for big paws, we've had good luck with the anti pull harness they sell at wal-mart on caine who is low to the ground but heavy and strong. also, you can try randomly changing directions on walks so that kentucky learns that he / she HAS to pay attention to you ALL the time. also, we had great luck with the "loose leash" command, and stopping our walk until they stop pulling. eventually they figure out pull = not going anywhere, then we introduce the "loose leash" command, where if the leash starts to lose even a little slack in it we say loose leash and they look and slow down. that one takes a lot of patience, but works great in the long run! good luck, keep us updated! i'm sure lots of others will have advice too!
