This is really dangerous advice!!! OP, please don't try this, and pajamajes, please don't advise people to do this!! There is a reason show like Dog Whisperer come with a warning to "not try this at home" if you will. This is a good way to get badly bitten or attacked if done to the wrong dog.
Eye contact is arguably the single most important thing you want to establish with your dog. Eye contact is the first thing I teach all my rescues and is the key to establishing trust, respect and effective communication.
