Tough love isn't easy but it is necessary...
oh this is a fun one and quite common. you get your little puppy, he follows you everywhere, comes when you call him to you when one day he realizes there is a whole world out there that is much more exciteing than you...well, this is when you become much more interesting and keep leashes on in an open area. work on obedience as much as possible, as positive as ever and never ever get mad at the pup for not listening. she will know your angry and then defenitly will not come to you, may shut down and then your relationship is screwed for a while....here, ill let you in on my biggest secret when recalling young puppies...RUN! RUN away from them, they will follow...thats all im gonna give out ...good luck!
oh, and something else that was not mentioned...a tired puppy is a good puppy..
im not sure how old you are or if you have kids but there like teenagers at that age. testing boundaries in everything they do. which means you need to have an even firmer hand with her. make sure that she understands you are boss. now i know that this is easier said than done. tyson was the biggest PIA puppy i have ever met but is now....still a PIA but has settled nicely into a mature PIA and not one who runs rampent blowing me off...get what i mean?
