Oh wow, I feel your pain... Uni has the thinnest most fragile hair ever! I want to grow out her hair b/c she has such loooooong legs and if she where short or shaved she would be mistaken for a reindeer or giraffe!
Her hair is about 5-6" long now, BUT she itches and breaks off her hair in some spots.

: anyway, I have been brushing her since she was a baby while she was sleeping, so she doesn't mind. If your pup if yelping... you're too rough. Try it while he's sleeping and use a light hand!
