@outlawingrace She sounds overstimulated.
Since she is hurting you I would start muzzle training for walks. There is a great sub to advise on it you can find through the search function. Or ask and I can clarify it.
I think you should have a training session (I like to work on mat training [sit, stay, lay in place for a duration], door manners-sit and wait calmly while waiting for signal to come, recall before walks at this age) and playtime inside (perhaps a flirt pole?) to wear her out before you even go on a walk. You want her to be mentally and physically tired before you even start.
Before you leave the house you want her to be calm and relaxed which is why the mat training and door manners get worked on right before the walk.
Walks should be shorter. Since she’s overstimulated, cut back on the stimulation by shortening the walks.
Keep a greater distance from people, animals and other triggers.
9 months is teenagerhood and in line for the second fear period so things can be extra challenging at these times.
