shed out

1. Of an animal, to shed a particular coat of hair or fur. It can be used transitively or intransitively. For some reason our mare isn't shedding out her winter coat properly. I know it doesn't look very nice now, but your dog is simply shedding out his puppy fur to make room for a beautiful new coat.

2. To move a sheep that has recently given birth to a different, typically better, pasture. OK, it's time to shed out that sheep now that she's had babies.
