Question: is the pink dog in blues clues a boy

Answer: No, Magenta is Blue's best friend, who is identical to her with the exception of a magenta fur coat. She is frequently seen amongst Blue's classmates and visited Blue's home for a play-date in one episode. She is often seen as an attendant at gatherings or special friends taking place at Blue's residence, and later acquires a pair of purple eyeglasses in one episode which she keeps for the remainder of the series. Magenta is shyer than Blue. Steven Burns stated in an interview that both she and Blue are girls.
