Did anyone see the hypnotist dog on Britains Got Talent ? If you don't want to know how it is done, don't read any further. OK, this is probably how it was achieved.
There would have been a pre televised set up. The hypnotist (the girl) does a quick test to find the most susceptible people in the audience,( you will have seen that the people who came on to the stage were conviently placed.) She would then have hypnotised them and told them that when they come onto the stage and look into the dogs eyes, they will fall into a deep sleep. It is as easy as that.
How do I know? Well, I have a Diploma in clinical Hypnotherapy. I have on occasion had fun with willing paticipants although I don't take it too far as I don't like making a fool out of people. Some people are just floppers and can literally go into a trance at the click of the fingers.
Cheers,
