When members of an animal rescue centre in Udaipur found Kalu lying in a hole at a construction site in October last year, his wound was gut wrenching. 

Animal Aid Unlimited (AAU) recently uploaded a video of how they treated "the most heartbreaking wound we had ever before seen" and the miraculous recovery of the wounded dog to good health thereafter. 

Describing how they treated Kalu, the AAU on its website wrote, "His face looked like a bomb had exploded between his forehead. The horrific gaping hole was infested with maggots that were literally eating him alive. As soon as our rescuers Ganpat and Kalu Singh brought him back to Animal Aid we decided that euthanizing him would be the best decision. But as Kalu stood there on the examining table, something in his spirit stopped us in our tracks and we knew we had to give him a chance."

"We put a powder into the wound that kills the maggots and gave him IV fluids while we waited for the powder to do its job. Over the course of the next 3 months, Kalu astounded us with him strength of will, his incredible healing and all the love he had to give," it added.

Kalu has grown a new face now and a new chance at life.
