Awww Liz hugs for Dulce, poor baby.
One tip I think you could try too, is to give her vinegar baths. I use them myself for all these types of things. It's a natural astringent, and is very very soothing. Vinegar of course won't harm her. Granted it might sting a bit but can't be any worse than what she is going through.
Trust me it does work, and it won't hurt to try
Good healing vibes.
