My 5 month old pitbull has been doing fairly well with learning some tricks such as "sit" and "lay down." However, I can't seem to get her to learn "paw." Whenever I try to teach her using treats as a reward, she focuses primarily on the treat and nothing else. She will stare at the treat and ignore my command. If I put the threat in my hand with a closed fist, and use my other hand to demonstrate I want her paw, she will sniff and lick my hand, likely looking for the treat I just had in it.
Is there a better way to teach this? The usual technique of giving her a treat when she does it correctly isn't working for me here.
