I saw some one time with my original duck dog. He was older at the time. The otters would dive and swim but I was running beside them in the boat. They would surface and act shocked that I was right next to them.... If Ol' Red Dog had jumped in he would have gotten more then he bargained for! Used to see a piebald one in one spot. Have watched them from the Hatchie river to Barkley and several spots in between. Seen one at Reelfoot. LOTs of mink on Reelfoot!
