Answer
Hi Ranjith,

It's pretty obvious that this is a problem that needs to be seen by a vet. I am not a vet, and even if I was, I still couldn't do anything for you online.

He needs to be seen to determine what has happened to his leg. There are too many things dogs can do that can be problematic to even explain, so it's best if you have the vet look at it and possibly take some xrays.

I hope that it is something minor and that he gets well quickly.
