What a difference a dog can make. Everyone knows about dogs being used in police work, although some (rare) courts are now requiring proof they actually can do all that is claimed. And they’ve already proven their usefulness in getting young, scared children to tell their stories to prosecutors — and even helping them testify. I have no quibble with that when it’s done outside the courtroom.
Instead, since the law doesn’t allow children to take their entire families into the witness box with them to help them testify, dogs are being used instead.
