Maybe the original crew of dogs weren’t trained for this purpose. People might think that any dog will smell a child’s blanket and then run through the woods right to him, like on TV. However, I think it’s much more likely that the average dog, even a ‘coon hound, would run right to the nearest spot another dog peed, and then look for a ‘coon to chase.
Dogs brought in last night, apparently from theis company http://scentevidencek9.com/Home_Page.html
Distinct possibility.
Hopefully there is scent, and hasn’t been masked by trampling.
