US Patent 7146935 Animal training method

A method for training an animal to proceed through an enclosure begins with the act of providing a generally clear or translucent enclosure having a first end, which serves as an entrance and a second end, which serves as an exit. A trainer encourages the animal to enter the entrance and can walk alongside the enclosure allowing the animal to generally observe the trainer to reduce any apprehension and to generally encourage the animal to proceed through the enclosure. Subsequently, the clear or translucent enclosure is replaced with an opaque enclosure once the animal has gained sufficient experience and comfort with the clear and/or translucent enclosure.
