After 1.5 months, my puppy's coat grew a little longer and became thicker
except for the hair on her nose bridge. It's very sparse there and I don't even know what the problem is. If it's winter/leather ear, I don't see any black slimy stuff on her ears. Does the black stuff also appear on the nose bridge? Her nose bridge is black with sparse short hair on it. It seems it didn't even grow in the past month
Help!
