A Stray Dog

The Chinese believe that if a dog strays to one's house,LUCK comes to the house. I am still waiting to check if it's a myth or fact/truth. This dog has been with us for almost 3 months. It refuses to go away. Rain,shine,thunder & lightning,it would just lie down near my gate,barking and chasing at people & at everything that passes by my place. It used to wear a dog licence-collar judging from the lighter shade around its neck. My cousin said,"It looks like a wolf." I do not like dogs or any kind of animals for pets. I do not know how to get rid of it. Any taker for this dog.?
