Attacked by a pet dog in Sec-8, Vashi

Me and my wife were walking on the footpath around 10.15pm last night. This is the road between Sagar Vihar entry and Vashi lake. A pet German shepherd dog leaned out from one of the row house walls and scratched my wife’s shoulder. It nearly missed biting my wife’s ear. We were in shock for a minute. Then when we complained to the dog owner to keep it on leash, he didn’t even acknowledge its dog’s mistake and started fighting with us. For our safety, my wife has started with anti-rabies injections. The house is between Lane G and Lane F in Sector 8, Vashi. They have a big German Shepherd that is kept unleashed in the lawn space outside the house. It has a low heighted wall, and the dog keeps leaning outside and attacking pedestrians walking on footpath. I am thinking of filing a complaint to NMMC. Can I also legal action can I take against the dog owner? What can I do to make sure that the dog owner is punished.
