Jack, an aptly named 17 pound Jack Russell terrier more accustomed to chasing squirrels, treed a mountain lion near the family farm in Colman South Dakota. The Argus Leader has a write up about Jack, Virtus and Chad Strenge and a day they probably won't forget anytime soon.
[Jack] chases squirrels around their Colman farm every day, but he made such a fuss Tuesday morning that Virtus, Chad's father, had to step out of the shop to investigate. They could hardly believe what Jack had found. "He comes running back in saying, 'Get the gun, there's a mountain lion out there,' " Chad Strenge said. "I said, 'Yeah, right.'"
