Hello, I rescued a stray from the streets 2 months...

Hello, I rescued a stray from the streets 2 months ago and he was extremely skinny and extremely weak he was not able to sit without opening his legs wide open and sitting in a postition a human normally would. He stayed for a week in my care at home and I fed him started introducing the leash to him walking him and he was improving and he started to play fetch and run and respond to my comands. Later me and my mom decided that we should find a good shelter that can provide security for him because we were unable to keep him and I have 2 dogs already and they were not getting along so well. So we took him with his food and everything and i tried my best to go and check on him every once in a while, it was very far almost on the other side of the city. Last time i went to check on him i noticed that the guy that works there that normally puts him his food everyday was not promising, by that i mean once when he was going to put him his food i noticed that the dog immediately put his head face down as if he was receiving abuse from this guy and he always limps to the other direction whenever that man is facing him. I told my mom i didnt frel good ab the people there or the place and eventally i convinced her to bring him back he came back in a worse state then when i found him. All his bones are showing he has absolutely no control over his 2 legs and hes is unable to get up or sit down ( always in this postition in between) and it looks very painful and he cant even eat out of his bowl. Ive been making him boiled chicken mixed with soup and rice and bread and when i put his plate underneath his chin hoping he will eat... he doesnt so i try taking with my hand and feeding him in his mouth not caring if he will bite me or not and he takes it and eats a little but only till he stops accepting more. Please tell me anything i should be doing or anything i didnt do yet because im in need of help and i dont know how much longer this dog can survive like this. Thank you
