This presentation could be due to a trauma or localized spot of skin infection (likely to be caused by bacteria or fungal). A check up, appropriate disinfection and possibly antibiotics or antifungal meds (oral, topical or in a shampoo formulation) are needed to solve the problem. Disinfection can eventually be started at home with very diluted hibiscrub or betadine or salted water baths. Buster collar may be useful as well to avoid any licking. 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.

    Hi there and thank you for using pet coach to address your concern. Without pictures it is difficult to say what this could be. A bacterial or fungal skin infection could do this as well as allergies or trauma. I would recommend the following: 1. Douxo PS chlorhexidine combination shampoo and bathe twice weekly 2. Malacetic conditioning spray and 3. Zymox topical ointment If there is no i.peovement or the area worsens, I would suggest having a veterinarian examine this so that an appropriate diagnosis can be made and treatment administered. I hope this helps guide you in the right direction. Please do not hesitate to contact me with any further questions or concerns you may have.
