Couldn't get the link to work so I don't know what all the excitement is about.

Though I've seen critters I could onlt describe as "mutant." Though they were actually hybrids. My little ranch I had borders on the Rez. There are a boatload of feral dogs crossing with the yotes.
While out riding one day my son and I noticed we were being shadowed. A pair of canines that were VERY odd looking. Higher and heavier in the front tapering to slim hips. Big stand up ears, bushy tails, large heads and dark solid colored. Like a cross twixt Wile E and a hyena. They were out of range of the arms we were carrying as I was packing a pistol and my son had a shotgun otherwise I would have took them out.
They were quite formidable looking. If I'd have had my rifle they would have been toast. They were better than 200 yards out but were quite visible through the binos. Quite weird looking. Rather scary actually. I've never seen them since that day so they must be picking on the Tribes cattle and sheep.
