Help Disco's maggot-eaten back heal

On 6th April, a chubby decently old pug came walking near our gate. I was at work and so our house help video called me, showing me this wrinkly old pug, seemingly abandoned. Harsh and the help took him to SKS Vet Hospital where we found two deep maggot-infested wounds, one on the ride side of where his thigh began and the other just above his tail. The maggots had eaten through the muscle in his leg from one side to the other.
We admitted Disco at SKS so he gets a clean space and the isolation he needs to be infection-free and slowly begin the process of the wounds healing.

Disco's wound is the only problem we know of now but since he was found on the streets, we cannot say for sure how long he has been out on the streets or what other conditions exist besides this. He is a work in progress and we will run tests when he's a little better, wound-wise.

For all this, we need help with getting his bills paid and prepping him for adoption. Do donate generously and spread the word to your friends. The more help me have, the easier it becomes for us to help Disco and scores like him.
