I have to admit that from the pics I cannot really understand if there is only one lesion or more bumps/lumps there. Generally speaking, 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. Skin scrapes and small biopsies (if not already taken) can help to diagnose underlying cause of it. Disinfection may 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/scratching. 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.

    I’m sorry to see that Gizmo doesn’t feel well. Those lesions on the skin could be a very deep bacterial infection, fungal infection, or even an autoimmune disorder. A biopsy may be helpful in determining the problem and the best course of action. I would also recommend a deep tissue culture to find out what bacteria may be present. Antibiotic therapy and soaks in Epsom salt or a medicated bath may also be indicated. Best of luck and I hope you find an answer and he improves soon. Thank you for using Pet Coach.
