Here's a video of our first efforts. Charlie already knows how to retrieve a ball to a net at shoulder height and now I'm trying to get him to slam dunk a ball into a basket that will require that he stand on his hind legs to do so and maybe even jump up a bit. Unfortunately, 2-1/2 ft. is as low as the rim on this little basketball hoop will go, so I'm trying to create a more realistic increment by using his trick pedestal. I'm not exactly sure this is the right approach, so suggestions are certainly welcome. Right now, I'm backward chaining from 'feet-up' on the rim and dropping the ball into the hoop. Could I also work with him to retrieve a tossed ball back onto the pedestal as a separate behavior at the same time as I am training the drop into the net behavior if I removed the basketball hoop from view ? I'm not sure if that violates the rule "Only shape one behavior at a time, or not".
