Ruby, Christmas Dog and reading

I spotted Ruby listening to 'Christmas Dog', quite intently, and Marlane suggested I take a photo. Should have thought of it myself, of course, but I was quite engrossed in just watching her.
The dog has a spot on the side which, when pressed, makes the dog say 'Merry Christmas Woof Woof Woof'. 
It amused Ruby for a while but then she put the dog down and decided she'd read a book instead.
