I don’t have much new to add that others haven’t already said.
Just some of my own personal experience this winter;
I know you’re farther along in tracking with Pan than I am with Sundance but when I brought Sundance out for tracking after not having tracked for a few months he was going way to fast also. I went through all sorts of things that I could have done wrong. Watched and re-watched the video several times.
For me part of it was how I laid the track and part was just how little tracking he has done.
For us, we needed more bait at the beginning, smaller pieces of bait, and I needed to walk normally

. (Trust me you don't want to see that video.) So, I personally needed to be more careful how I laid the track. And then a few more times out and he’s right back to the pace I like.
Yes, the way I have been taught, you have something at the end of the track from day one. A ball wouldn’t be a good idea with Sundance (or Dalton) so we use a flat 3”x5” (approximate) Gappay leather tug (no stuffing) with a handful of bait (treats). It lays flat on the ground like an article but is way to visible when there is a little bit of snow. It also helps me to know where the track ends.
A prong would also not be a good idea for Sundance at his age, probably not very fair just yet either. He has to learn what I’m expecting a little more first. However, we do use the prong to teach him to calmly walk up to the start position and sit. Then we switch the leash to the flat collar, leash under legs and the prong comes off. Command given to search – off we go. If I don’t start him off slowly, he’ll drag me to that little orange flag at warp speed! Trust me, I'd have some nasty grass stains on my face.
Amy – I am not sure but I’m guessing that Lisa means at the end of the track since she said
“removed the ball from the end of the track”.
