I think it depends on the command and the trick. Marta learned everything pretty quickly, but she loves to show off her tricks and will work for free with these (especially speak, it's her favorite) because she gets such great feedback from her "audience."

Adele was harder to teach, I think because she gets too caught up in the reward and doesn't pay attention to what she's doing. She has a great recall, though, which is really important.

Has anyone here tried "clicker" training? I've always wanted to try it but for some reason never done it.
