We're back...
No foreign bodies, no parasites, not fungal but could be a type of dermatitis (sp) although its normally on the pads and Soaps sore bits are in between her pads. So still a bit of a mystery really! Got the same treatment as before (metacam, synolux, hibiscrub and buster collar). Fingers crossed it doesn't happen again!
If it does then they will go down the dermatitis route which would mean steroids and they didn't want to just put her on those.
Fingers crossed she is just getting "sweaty toe jam" (yuck) and overgrooming...
