Make your dog give you a hi - five
Ok this should work because it worked for me ok. Call your dog then get him/her to sit then hold up his/her paw then tap the light bolb with your hand then say hi-five then you do it a couple more times then you just say when he/she has lernt it hi-five then u just tap the dogs hand easy really easy its good in the obedience trials for when you can do the free one you get 10 points :) Hope it works for you :)
