Thanks guys, I definitely didn't cut her, it's definitely a matting sore, thanks for the sudocreme trip but am worried she can reach it, we are taking Mo tomorrow for his snip so will ask for suitable cream there... We may have to take her in for a shave, it's just a bit unmanageable right now, we do use a metal comb, the furminator. But it doesn't seem to be doing the job this summer, like I say, never had an issue before, think its the run of weather...
