Street Dog needs proper treatment

The dog has suffered a lot in his eyes, for which he could not walk properly. The dog that runs around the whole day, Now he is still sitting silent in the one place. Can not eat anything. Not even eating food. He just cry all day. Sometimes screaming and screaming loudly. I want to treat this dog. But for this it needs 500$ for his treatment. If any kind of mercy helps the dog then the benefit is for the dog.

Come forward to help the dog.
