It is pretty rare that I ask my dogs to do two things at once, and I've realized that it is really difficult for them! Even combining two behaviors that they know is hard. Some of our first multi-tasking experiences involved asking my dogs to hold a dumbbell or other object while performing another task--teaching Lok to grab an object out of the fridge, then turn around to close the door was interesting! Both Lok and Jun would tend to drop the dumbbell before using their paw to shut a door. Jun had a really hard time with sitting from a stand while holding a dumbbell! I pretty much had to trick her into it the first few times until she realized that she actually could sit with something in her mouth!
Jun is currently learning two multi-tasking behaviors. The first one we've been working on for a couple months--jumping over my leg with a disc in her mouth. That is part one of a two-part trick we're hoping to put into our disc routine this year, and she's finally getting it down! The second part involves releasing the disc into my hand at the top of the jump, and that might take awhile! It would be a lot easier if I could give her a verbal drop cue! We are probably going to do a vault-less freestyle routine this year, so we need to build up some more complex tricks and sequences that do not involve vaulting. I have no idea if this will ever be ready, but it will be cool if it works!
The second multi-tasking behavior is holding up her left paw while targeting my hand with her nose. We've just started working on this the past couple days, and so far she's still putting her paw down to do the nose target most of the time. It's especially hard because my accuracy with the clicker is sucking. I'll think she's gonna hold her foot up, but then she'll put it down right as I click! The idea is that if she learns to hold her foot up while targeting my hand, I can just move my hand further and further away and she will have an automatic limp! I never was successful in teaching Lok to limp more than a couple steps, so we'll see how far I get with Jun. Currently, I am annoyed that no matter what I'm trying to work on I get a paw raise--the downside of being in the middle of shaping behaviors that haven't been put on cue yet.
