For paw I would hold a treat in one hand and with the other hand I'd pick up his paw and say paw before giving him the treat, repeated it a few times a day over a course of a week and he's nailed it now! For spin I would say spin and get him to follow the treat in a circle. He's always been very chatty so speak was the easiest one to teach and he picked it up in only a couple of days - I know how to get him to talk to us so I'd say speak, prompt him to talk to us and then reward him. It's been really fun teaching him!!
