Link and I have been having some trouble with contacts. He does them fine on the bottom of the obstacle (on the A-frame, decent on the dogwalk), but when we start doing the whole obstacle it falls apart and he comes off the contact. If someone is waiting on the other side and puts treats on the target he does ok, but usually I'm working by myself. My instructor suggested having him jump up on the side of the A-frame using a table, or lift him onto the dogwalk and start working backwards, since it really seems he is having a hard time slowing down, and on top of it doesn't really understand his back feet have anything to do with it. I did a little bit of that though and it worked better. We also have a target box at home that we do back foot targeting with, but I don't know how to transfer the behavior to the contacts. this is my first serious agility dog, so I'm pretty confused on how to address this. Any suggestions?
