The main issue is that she has a large sore on her side from scratching that does not clear up (It has been about 12 weeks now since we first spotted it.) It has always remained very dry/odourless and doesn't bother her when touched, so I haven't given any antibiotics yet, but it is definitely getting bigger over time.
I have tried bandaging her both with vet bandage and socks, but she is incessant and will always wriggle/chew her way out. I have also tried manuka honey, but then realised this would be counterintuitive when she started licking at it

Today I noticed that it is starting to protrude slightly so am going to put her on a course of baytril to see if this makes any difference. I have also just ordered some bephar wound ointment and some johnsons tea tree skin cream to see if it will help (anyone had any experience with these?)
At the moment she is absolutely fine in herself but it is worrying that it still hasn't healed after so long and mite treatment doesn't seem to be going anywhere. In theory is there anything stronger than ivermectin to treat with? Could bathing her regularly with an emollient cream/aqueous cream help?
Thanks
