The dog with a smile

My name is Emily,I have a little brother named Evan,Evan doesn't bother me as much as I wanted a dog,I always wanted a dog so we got one. This dog isnt the normal dog you see barking,peeing,growling. It does those things but it has this weird thing thats like following me and Smile dog. It has white skin and black hair,to me hes like out of a horror movie scary. But this dog talks at night,he one time tells me to spread the word. I don't know what that means. M-Maybe its just my mind playing tricks on me,I'm not sure. I think I'm the only one who can see and sense these things.
