Alanis weighs 46 to 48 lbs, a nice size. I noticed, however, that when she's on the grooming table and I'm trying to strip her coat, she grrrrooooowwwwwwsssss to the size of a 100-lb Airedale Behemoth, more than doubling the number of square inches of fur.
As for her head, I work and work and get maybe a handful of fuzz. I'm not trying to do a full strip--she'd be the size of a Clydesdale by the time I finished--I just want to strip out enough to keep the color and texture of that thick, thick coat.
