Charlotte has been shedding quite a bit for almost 2 weeks now, I mean clumps of hair coming off around her tush. Hair coat doesn't seem to be thining and she doesn't have any bear patches but she seems to be losting quite a bit of hair. Is that normal for a basset? If so is it normal for them to go through a big shed this time of year? Its been a really cold Dec here in DC and I don't want her to be without her natural protection.
