I have a question about Lani blowing her puppy coat. Is she too young, she was 4 months on the 25th. Do they loose the coat in clumps? Lani has a spot on her left side where she looks like she has been shaved, it is about a 3in x 2in area. The fur that is there is darker than the rest of her fur. We have been finding clumps of hair on the carpet over the last week or so. We want ot make sure this is normal and not a sign of something else. Thanks.
