It's been a long time now but I remember a way while back when Nancy Grace had on a dog and his handler (nice blonde lady) to demonstrate how the dog would react to decomp. They had put a piece of clothing that had the decomp on it hidden in a couch or chair prior to bringing the dog on the set. I don't think I've seen a dog more excited to find a piece of clothing, and he went right to it. He acted as if he'd hit the Vegas jackpot in rawhide bones and treats!
I was so impressed by that. These dogs are so specially trained, and they have the proof of it, so JB objecting to this seems very silly to me. It's not like they asked my cat, who does fetch but wouldn't know decomp from the man on the moon, to sniff in the A's backyard. These dogs are trained professionals.
