Female dog suffers hundreds of blood sucking flies

This is a stray dog a very shy female dog. After making the video I tried with some sprays which i use for my dog but this dog didn't stay for long.. i was able to spray a few times but hitting the exact point under her neck was a difficult job.

May be the spray wont work for long because she will soon go to a nearby water body and take bath again and get a coating of mud on her.
