Address:

Plot no. 17,Block A, vikas vihar ,kakrola 110078

There is a stray dog in our neighborhood who bites everyone. He bit one lady so badly that she fainted due to blood loss. He bit my dad today as well. There is one family who feeds that dog and hides it whenever dog catcher van comes. Please help us out. There are many dogs but that one particular dog is the problem here.
