I am convinced but then, this fits the theory of the abduction that I've held since I first heard about it.
On the other side, Aunt TB is not a handler of high level tracking dogs, so far as I know. I find it unlikely she was well acquainted with the specific dogs that were there and the way they work because both dogs were flown in.
Without some serious education in how scent dogs and particularly scenthounds work, what she's saying there is the guess of a layperson. Maybe she's right (I think she is) but maybe she's wrong.
Bloodhounds do tend to be whiny, vocal dogs. A lot of them vocalise when they are looking for scent and they vocalise after they've found scent and are actively tracking. But it's like any dog--you have to know that particular dog to know what those particular noises mean.
Anyone who has lived with a house dog probably knows that dog's particular way of communicating they need to go outside. Every dog varies and only someone who knows the dog will know what it means when the dog does it. To anyone else, it's just meaningless barking, whining, pawing, nosing, staring or whatever.
