hi i really need your help. my ess bitch who is a year has 3 red patches on her skin they look really sore have lost the hair on the area and are covered in small scabs. i am baffled as to what they are. we have been to the vets on numerous occasions and they keep giving us stuff to try that work but then its back in a week. every day it gets worse. they have took a scraping and give us treatment that they said would heal it but what a surprise its back. i dont no what to do anymore. she is not itching it but it looks really sore. anyone any ideas!!!!!
