Should we be worried?

Luke's favorite word is "dog" (granted, he doesn't have THAT many words to choose from). He sees a dog on the street..."dog". He hears a dog bark..."dog". We start to walk outside where the dog lives..."dog". We start to come in the gate from the street to the yard where the dog lives..."dog". We get near the window where he can see the dog outside..."dog". He sees the camel in the nativity scene..."dog".
