@siskie no matter her age, and three weeks, she probably still isn't even being herself around you. you CAN train her, but first you need to create a bond and work on gaining her trust. when i got my dog (following the death of the best dog ever), i was really scared because we didn't seem to be bonding the way i thought we should. in reality, she was just too nervous to let down her guard. once she learned that i was a safe person, the bond developed so quickly.
also, if you want to adopt a dog, you have GOT to be patient.
