When I first got my girl she had a dry patch on her back with no hair on her back it was the size of a dime.....I thought it was something that would go away but it seems to be slowly spreading it is now the size of a quarter......do any of you know what this could be and if there is anything I could put on it to stop the spreading so that hair would start growing again......her hair is healthy on the other parts of her body......I will be taking her to the vet next month for her shots and will ask him......that is why I have not taken her for a consultation on this as yet......any helpful advice would be appreciated.
