In his younger days he did not get along well with Dale's other pets and Dale gave him to a rancher down in the valley.

Pedro was back in Dale's camp next day.

From that day Dale began to care more for the hound, but he did not want to keep him, for various reasons, chief of which was the fact that Pedro was too fine a dog to be left alone half the time to shift for himself.

That fall Dale had need to go to the farthest village, Snowdrop, where he left Pedro with a friend.

Then Dale rode to Show Down and Pine, and the camp of the Beemans' and with them he trailed some wild horses for a hundred miles, over into New Mexico.
The snow was flying when Dale got back to his camp in the mountains.
And there was Pedro, gaunt and worn, overjoyed to welcome him home.
