One thing I did with Sacha was a I made a "makeshift" leash out of nylon cord (that you get at Home Depot or Lowes). It's really light...I tied it onto a regular leash hook (and I made it about 25 feet long so I could work on long stays, etc).
First, as we were walking, I'd drop her regular leash, so it was dragging behind her...and I let her see both my hands (so she could see I wasn't holding a leash)...but because of the weight, she knew it was on her...
Then, I went to the nylon cord. I would hold it...then I'd drop that and let it drag behind her. She still knew there was a leash, but it wasn't nearly as heavy as the leather one...
Once I got her reliable on that, i started to take it off....
