In Response to Hodgey
It is normally twice a year, for entire bitches they will loose More coat than entire dogs, who may not have a full moult after the big puppy moult at about a year, for some years.
Mine is a double coated breed and it normally takes about 3 weeks for the undercoat to come out and another week or so if they are going to drop the top coat.
Moulting is governed by the amount of daylight, and to some extent the weather so artificial lighting and heating can confuse things.
I have found neutered animals are inconsistent with their moult seeming to stop start or loosing a bit all the time.
