if it was me and I wanted to be a pain in the butt I would; trim your fence so it is within your property line, install a fence within your property where hers does not come clear to the property line, and then complain to the HOA about her lack of maintenance when her grass in between the two fences is allowed to grow unabated.
be warned though; in the area where she has property on your side of her fence; if your dogs go to the fence, they are on her property. You would be liable for and damages they cause either to the fence or the land itself (urine burns, fecal matter).
This really isn't a fight you want to get into. It can get real ugly for both sides. You should make an effort to find a peaceful solution. You will both likely be there quite awhile and it usually only gets uglier with the passage of time.
