1. Hold the treat so she knows she's getting it, tap on shoulder of the leg you want her to lift and say "FIVE" and shake her paw in the motion you want her to do and give her the treat.
2. Do this repeatedly and one day she'll do it.
Emma's first one was quite soft in the way she delivered it, like she wasn't sure. Now I don't have to have a treat at all.
Oh yeah, don't say "Gimme Five", just "five." You can throw the 'gimme' in later. Keep the command at one one.
