Hello, my name is Dr. Elizabeth and I am happy to help. Pets' can get rashes for many reasons. Some times you can care for it at home and sometimes they need to go to the veterinarian. For Boba you can try home care first. The first thing to try to figure out is how to protect the area from further scratching. It's a tricky because this portion of his neck won't be covered with the normal elizabethan collar. You would try a loosely fitting dough-nut style collar. Or the end of a tube sock cut to loosely fit around the area. A doggie turtle neck would work but it might be too hot where you live for that. Try to figure something out that covers it but not a choking/strangulation hazard. Next, wash the area once a day with either plain hand soap (like Dial) or a medicated pet shampoo. This will help to control the number of topical pathogens as well as remove oil and dead skin cells. Rinse the area well and gently towel dry. Lastly, apply a topical antibiotic twice a day. Just a dab will do and rub it in well. Make sure the skin is dry before application. Neosporin is fine to use. Keep him indoors, clean and dry. You can get hydrocortizone cream for pets and apply that once a day, try to apply with at least 2 hours after and before the neosporin. You can also give him benedrl every 8-12 hours. If the spot is not much better in 1 week, if it gets worse at any point or if the lesion is not completely healed within 2 weeks, Boba needs to be examined by the veterinarian. I hope this helps and please feel free to reach out any time.
