Municipal Corporation Of Kolkata — A sick stray dog

There has been a stray sick dog visiting our locality(Alimuddin Street)for the past week.This dog has a disease due to which it has an unbearable smell.At night he comes and sits at the main door of our flat(5A, Alimuddim Street).Due to the blood that his wound sheds and the smell we constantly have to wash the doorsteps of our house.
This has been happening everyday for the past week and its almost unbearable to smell in the area where he sits.
I would be grateful if this matter is looked into and that dog is taken by the canine control to a shed.My contact details are:
