This is normal. It might also look thin because the hair there might be silver compared to the rest of the darker hair? My Chloe also had hair that seemed thin on her head when she was a puppy but that was only because the hair on the very top of her head was a little gray-ish compared to the rest of her head hair. She is 13 months now and her head hair is much thicker and blonder. Your pups hair will grow.
