Hi, I am afraid to tell you that this wound and the biting is secondary to a primary problem that is likely to be an ulcerated mammary tumour. I would really recommend to have Becky checked over as she can’t be left with an open wound that will just attract flies, parasites and must be extremely painful as well !
