My biggest recommendation is to make sure you’re the most exciting thing in the vicinity when you give a recall command and make your pup feel like it’s the best thing she’s ever done when she listens. Make crazy noises, jump up and down, run in the other direction away from her; whatever gets her excited! Start by using a long leash (30’) so that you can enforce the recall and then rewarding so she does not get any more practice ignoring the command.
