For cuddles, I taught Henry he always had to have a toy in his mouth. Even to this day, he scrambles off for a toy when he wants to say hello. This means you can cuddle without the teeth getting involved.
At 14 weeks your little one is at a perfect age to start teaching 'go to your mat'. I found an excellent video on YouTube, I'll have a look for the link. When Henry would attach himself to my ankles / apron / trousers while I was cooking in the evening, this command was a godsend. It gave him something to focus on and calmed him down.
On walks, have you tried dangling a toy or treat just in front of you on the side you want her to walk on? Something to get her focus might help.
Yes, she WILL grow out of this, and probably quite soon, but there are things you can do in the meantime. Good luck!
