her hair became heavily matted. We? recently brought her to the groomer and she shaved all her hair and left the head and the tail with hair. She looks weird and thin, my dog was affected and became really depressed. How long do you think will her hair grow back? She's not her usual bubbly active puppy that she used to be. She even walks awkward because of her tail. Can you help on how to deal with her... thanks.
