our gsd gril is 5months old weve had her about 6weeks now and over the last week we have notised its black and sticky around her bits , so ive been cleaning her to see if shes sat or lay in something , but the nxt day or so its back ?? ive booked her in the vets for monday but was wondering if any1 as seen this before ??  could she have an infection ??
ive always had girls and never seen this before !

thanks ,joanne xx
