When a dog wins its group at Westminster, it heads to a medal stand where it poses with its handler and the judge who chose it.
Or the dog could be reacting to a cue from its handler, be it accidental, like reaching for a treat to reward the dog, or, more ominously, on purpose.
The costs don't end there: while a bomb dog typically goes to live with its handler when it retires, dolphins require specialised care.
According to one account, she could even charm her way around animals: when a "vicious Alsatian dog, trained to bite and break necks," found her hiding under a bush with some partisans, she placed her arm around it, and "it lay down beside her, ignoring its handler's whistles".
It manages to escape its handler and elude capture for a significant period of time.
The Saint Peter's Peacock was formerly sassy; now it looks primed to maul its handler.
Its main weakness is that it must work apart from its handler.
Every service dog is a bit different when it comes to its training and its handler's needs, said Jennifer Boan, the annual fund and communications manager for Paws With a Cause, a nonprofit organization that trains service dogs.
As it turns out, Clever Hans was actually sensing its handler's bearing.
After indicating the spot, the dog returns to its handler, and sits down to confirm that it has found something.
But even with conscientious cops, a dog without the proper training may pick up on its handler's body language and alert whenever it detects its handler is suspicious.
