Just to add to the fun:

This spring herding promoted much discussion of stock that had not "weathered well" and of "dogies" and "dobes," these last being calves or yearling cattle that were still scrubby and anemic from the scant food of the cold months.

According to Black Cowboys of the Old West by Tricia Martineau Wagner (Twodot, 2011), the song "Good-bye, Old Paint" was composed by Charley Willis (1847-?), pages 110-124.

I don't find anything on either one in Katie Lee's Ten Thousand Goddam Cattle.
