I have a pup who is very food driven. Old school ways to teach him to 'give me your paw' didn't work. What worked for him was for me to have him sit. Then I'd have the treat in my closed hand and gently use one finger (of the hand that has the treat in it) to nudge him under his snout (upward), while saying, "give me your paw". He get frustrated and use his paw to stop my hand so he could sniff out the treat.
Never used that method before, but it worked for him. I can now just ask him and he'll give me his paw.
