Clever Hans the horse could do that over 100 years ago.
Clever Hans (German: der Kluge Hans; c. 1895 – c. 1916) was a horse that was claimed to have performed arithmetic and other intellectual tasks. After a formal investigation in 1907, psychologist Oskar Pfungst demonstrated that the horse was not actually performing these mental tasks, but was watching the reactions of his trainer.

I heard it from Mr. Ed’s mouth myself!
And Clever Hans’s owner didn’t even know he was cuing his horse.
A good reason why a lot of police dog alerts are invalid, and subsequent searches should be inadmissible. You can’t put the K9 on the stand.
Right, it’s an old trick.
Immediately what I thought off.
It’s an old scam.
