They do get affected by the work they do just as they can be fooled by human intervention. This is why in the absence of their indications leading to a positive result, their work can only ever be considered as intel.
In the McCann case - there are people who just will not accept that. Which is why as long as vitriol continues to be poured on the McCanns - "the dogs" will always have their day.

“When they train, they don’t search for hours without finding anybody,” she said in a recent phone conversation.
“You need to remind the dogs every so often that they do get to win.”
