Thought 'cardboard' ears was one of the rewards for having more than one dog, never noticed it causing a problem with the coat though so it must be a breed problem.
The breed Brainless and I have do loose coat but not through play, well it does not show, although you do notice pups in particular with a gob fall of hair and the birds round here would not be happy with anything else to line there nest with, they do however manage to have enough left to be able to strut their stuff in the show ring without being penalised for moth-eaten coats.
