I am assuming your baby got shaved. The hair grows back pretty fast, but that all depends on how long you keep the hair. If the baby is kept in full coat it could take 9 months to a year to reach long length. My boys hair grows very fast so that also has to be taken into consideration. I don't know what you mean by felt in the hair. If you keep your pup in long full coat he / she must be brushed and combed everyday to keep it from getting matts, knots and tangles in it. I keep my boy in a puppy cut year round, less work for momma.
