Municipal Corporation Of Delhi — "dog menace"

Address: Kalamandir Road, 110083

I want to get your precious attention towards our locality where stray dog's population is growing day by day. Not just their numbers are increasing, they are getting more dangerous than before. They bark at everyone who carries a bag, bark at vehicles and chases them. My sister got bitten few days ago by these over-aggressive stray dogs.
I know it is illegal to get rid of them but you can sterilize them so that they cannot reproduce in future and it will also help them to be calm.
Thank you!
