Walking Puppy HELP!!!!!

Help!!! I've been trying to teach my pup to walk on the leash with no success. She is constantly jumping up, chewing leash, running ahead, dragging behind, playing tug of war, hanging off my mittens,etc.

Does anyone have any suggestions. I've tried bitter apple on the leash for chewing, I've tried stopping and restarting over and over again (a 5 min walk turned into 20),
Any tips would be appreciated.

P.S. She is a handful but I love her to bits already (she's just under 4 months now).
