Dave is the light brown dog on the ground. Dave is so tired and old that he cant pull the sled anymore. He just collapses on the ground unable to get up. Dave was just to old and he could not adapt anymore.
Dave would cry out in pain. He wouldn't be able to sleep well. A dog driver came and tried to see what was wrong with him, but he found nothing. One night he was even pressed and prodded, the drivers just couldn't find out what was wrong with him.
One day Dave was so worn out and tired that he couldn't get up to get harnessed up. The dog driver then helped him up and brought him to the sled. All Dave wanted to do was to pull the sled and do what he loved to do. But it was getting harder and harder for him to pull the sled though.
The dog driver told Dave to go behind the sled so he wouldn't have to pull it. He thought that Dave would be happier. Dave was mad, he wanted to be in his harness pulling the sled even though it hurt so much. So instead of just staying in the back Dave went up to Sol-leks, who took his spot, and started nipping at him.
When everyone got to the camp Dave just fell to the ground and went to sleep. He couldnt even get up he was so tired.
When it was time in the morning to get up and into their harnesses Dave couldn't get up, so when they were about to leave one of the dog drivers went back. All the dogs heard a gun shot. It said that Buck knew every dog knew what happened back at the camp.
