Municipal Corporation Of Delhi — I'm complaining about dog on our street

Address:

2413 Punjabi basti,subzi Mandi, clock tower 110007

I live at 2413 punjabi basti, subzi mandi, clock tower.
Our neighbours have a dog and they never tie any band or chain to him. And he's a very aggressive dog. Anybody who comes in the street he just goes onto him and barcks like anything and bites and scratches.
He never lets anybody in the alley. As and when anybody comes he just jumps over him and starts to bite and scratch. Everybody is very angry about this and our neighbours careless attitude. They are always like do what you can we will not tie him any chain.
Daily some delivery boy/water man/dhoodh wale/ our helpers all get through this and are very much terrified.
Please see into the matter and do something as soon as possible.
