Municipal Corporation Of Delhi — stray dogs in new rajinder nagar are biting us all daily, even during daytime

Yesterday, while going to io bank, shankar road, new rajinder nagar, we found a lot of stray dogs basking in the sun, in j - block. One of the dogs suddenly bit me on left thigh and ran away. I have now got an open wound.
Last month a dog had bit my husband outside io bank.
Pl let me know why these stray dogs are not being removed, and for how many more years we human beings are required to be bitten by these stray dogs?
