Hi, and thanks for your question. This presentation could be due to a trauma or localized spot of skin infection (likely to be caused by bacteria). As a first approach, disinfection may be done at home with very diluted hibiscrub or betadine or salted water baths twice daily for a week. Buster collar may be useful as well to avoid any licking (if any). A check up, appropriate disinfection and possibly antibiotics (oral, topical or in a shampoo formulation) are needed to solve the problem if no improvement are seen in a week. Hope this answer was helpful, but please do not hesitate to contact us again on the forum or by requesting a consultation if you have any more questions or to discuss it any further.
