I rewalked the Castro Valley hill track again with Scout and then, 48 hours later, I ran the track again with Dino. Again, he was hesitant in the beginning, but this time we ran the track in early evening, so he may have remembered the last track, because heat was not a problem. Eventually he got into the track and he got all the turns and switches. He did have a problem when we got to the top of the track where there was access to an open space area, but I think this was based on seeing two other dogs in there and wanting to go play with them. I did correct him with "wrong" and eventually we got back to the track.
He followed it down the hill and got the switch across the street to the one way road. He got the cross over to Rolando, but he missed the first time of the cross across the street. I think he was distracted by some kids he saw ahead of him, but once I brought him back and I was more firm with him to "get to work" he got the street crossing.
On one corner near the end he missed the left turn and crossed the street, but he then did indicate loss of scent and we check all the corners and eventually got back on track. He followed it all the way down the hill and made the cross across the street. I ended the track just after that cross since the track had been long. We played with the rawhide and he got treats.
