My French Bulldog Baby G needs help

Hi my name is Rob I am an animal lover I have this little guy named Baby G he's going through a tough time because he got bit by another Frenchie and in the pictures it shows one hole but there is actually three I did go to the vet and they gave me antibiotic cream and antibiotic pills that didn't work and skin was dying and made it bigger and now it's at the point to where he needs to have surgery I am struggling with this unexpected issue the owner of the other dog did give me money $1,100 which is already gone as of today he went in to have it all cleaned up and disinfected as as much as possible and it's going to be sent home with an open wound for a few days for it to heal before they can do surgery which I have no idea how much that's going to cost me again. So I'm desperately asking for a little support as I don't have anymore money I've borrowed money from friends and family and I don't come from any money so that's only limited and money I have to pay back. this little guy deserves so much better and it breaks my heart to see him in this condition. I've tried the Humane Society and other places but nobody seems to want to help. So if anyone can donate something is better than nothing and Baby G be the little guy he used to be.
