Hi there, I am getting a lab puppy in the next couple weeks from a friend who is a breeder. My daughter picked out one of the seven puppies, the largest one in the litter. She is a lovely yellow lab, but what I have noticed is that her coat seems to be a little longer and than the others. My daughter calls her coat whispy. Is this a common trait? I have never noticed it before. Also, at 7 weeks, her teeth seem to be coming in slower than her brothers and sisters. Any cause for concern?
