Continuity mistake: When Travis finds Arliss and Old Yeller in the drinking water, he throws a rock at Old Yeller. Old Yeller is wet all over. Arliss then throws a rock back at Travis, and a chase ensues. After their mother breaks up the fight, she admonishes Travis. Travis then says something to Old Yeller. Old Yeller is lying on the ground dry as he can be. He was just in the water a little over a minute ago, yet there is no sign of wetness at all in his fur. (00:15:45 - 00:17:11)
