This dream is very difficult to interpret without some information about the context and/or what the dog said. Very generally, it might refer to a message from an unexpected source.
that you have a very vicious dog
It means nothing. It just means that in your dream the world exploded.
bad luck
What the HECK are you talking about?! If you have had this dream it means you are claustrophobic and nervous... I have no idea if that is true but i will do...........
that you are a cat person
it means that you don't trust her
Unless you dream about this happening often I wouldn't read much into it.
it means your gonna die
You Want A Hotdog :D
it means ur weird
Dogs hate you
its dreaming when dogs dream they make whimpering sounds as in expressing there dream to other dogs
