Last night around 4 am a dog thats furry and black and white, sort of like a black & white maltese, gave to our doorstep. It's got no collar and we're trying to make it go away but we don't know why its staying. Its pooed on our lawn too lol. It seems excited cause its tail is wagging. Why is it staying at our driveway and how do we make it go away? THanks.

P.S. Mums really afraid of dogs so we cant let it inside.
