Pluto: Yellow or Orange???

Usually every morning I fix Kayla's hair with her sitting on the bathroom counter. 9 times out of 10 it doesn't go very well. She's way too busy wanting to turn the water on in the sink, empty out the basket on the counter, move all around the counter, and her hair ends up getting pulled a lot as she is moving around. Needless to say, she ends up screaming, I end up screaming, and I just want to cut all of her hair off, so I don't have to worry about doing something with it everyday!! This morning, I thought I would try something different: I tried fixing it in the living room while she watched T.V. --She's not much of a T.V. bug, so she really wasn't too concerned with watching Mickey Mouse Clubhouse with Hayden. Instead, she would look around the living room, and see one of her toys, a book, a crayon or anything and decide she needed to hold it. So, really it didn't seem to help her "busyness" very much!! But at one point I asked her "Where's Pluto?" and Hayden (who I didn't think even knew we were in the room because he was so zoned out in the cartoon) quickly responded with "He's the yellow dog!" And Kayla who was crying, "I want my baby!!" heard him say this, and quickly said: "It not yellow, it orange!!" Then of course, Hayden had to respond back with "No, he's not Kayla, he's yellow!! So, then Kayla said, "Orange!!!" --And you can imagine how the rest of their "conversation" went!! So, my question is: Who is right? Is Pluto Yellow or Orange?
