Any dog can get flyblown if negected - you should see some of the DD types I've seen come out of pounds!!
Sorry to disgree Ashaari, and it is in the nicest terms of course!!
Lots of breeds have heavy coat around their trousers and tail area which quickly become badly soiled and a fly hazard if not cared for. It's an age old excuse for docking - not good enough. If you can't care for it don't have it. Cutting a tail off is not a replacement for management and care.
