The hair on Umas' shoulder under the top hair, has bands of lt. and drk. grey. The very ends ,inch or so, are the puppy black she was born with. The next inch or so is a drk. grey. The next inch or so is a ltr. grey. The next inch is the drk. again,and so on. Is this caused by the hormonal fluctuations? Perhaps she can't decide what shade to go there? LOL! Will she stay banded like that or go one way or the other? Her top is the very drk. grey, her underside is the lighter shade. Any ideas?
