I have a litter of 5, 2 blacks and 3 blues and all of the blues have, in varying degrees, very thin hair particularly around the rump. One of them is reduced to a tufty appearance and you can clearly see the skin. There is no redness or marks on the skin and no sign of mites at all. Is this associated particularly with the variety, or could it be something else more worrying?
ETA:
I bet it's more bloody barbering-why would they only target the blues?
