What it says on the tin. The leash itself can be a bit finicky, in addition to the extra tags, I recommend adding something along the lines of (disconnected leash, multiple leashes,):1.2 to the negative to help with the leash splitting or being discontinuous. Shared activator is l345h3d, with l345h3d_m0u7h being the leash handle held in the mouth, and l345h3d_h4nd being for the leash being handed to the viewer. Strength of 1 works best for me.
l345h3d, ((l345h3d_m0u7h, girl biting the handle of her own leash, holding own leash handle in mouth):1.1), ((full continuous single leash from collar to mouth):1.2) L345H3D, ((L345H3D_H4ND, GIRL OFFERING VIEWER THE HANDLE OF HER OWN LEASH, HOLDING OWN LEASH HANDLE IN HAND, HAND WITH OWN LEASH OUTREACHED TOWARDS VIEWER):1.1), ((FULL CONTINUOUS SINGLE LEASH FROM COLLAR TO HAND,):1.2)
