Hi. I'm pretty new here too so i'm probly not the most educated on all things puppy but i'll try to help. Walker just turned 12 weeks and he is a potty training angel. so potty training i can't help much with. But when it comes to the pant leg thing i feel you, Walker does it too. I've tought him to sit and whenever he starts attacking legs we say no, then have him sit and give him a treat for sitting. He's stopped attacking our legs unless we're actually playing with him, we're still working on that. I've also heard that squirt guns may help. best of luck.
