Lucky dog needs your help!

My husband Christopher found this poor dog on the side of the road, left for dead. He couldn’t get up. Obviously hit by a car. We are doing everything we can at the Veterinary office to save him. No broken bones appeared on X-ray but he has bruised lungs, and a stomach full of dirt from laying there so long. His front legs have infected wounds with a high white blood cell count. He still isn’t wanting to get up but has feeling in all his legs so we hope with medication he will start to move a bit more. We plan on giving him a loving home if he survives but need your help! 

I will post updated pictures when I can !
