Little pupper doggo

On his way home from the school today, Charlie saw this little doggo had been hit by a car. Unsure of what to do, he acted instinctively, picked up the pupper, wrapped him in a towel, and brought him home. As soon as he got home he asked me to come out to the car and see what had happened. This little guy had been hit and left, so we bundled him up some more and he sat in my lap on the way to the emergency vet. Upon getting him there, they told us he was microchipped - as it turned out, there was an error with he scan. He isn't microchipped, and he wasn't wearing a collar. He's also intact, and the vet said with all of these he's most likely a stray. He was hit in the head and over the next few days will need to be monitored 24/7 because he is suseptible to seizures and they aren't sure the extent of his injuries. Without the appropriate funds, little guy will not be able to receive care, and will most likely have to be put down if he doesn't show signs of improvement on his own. Even if this duder doesn't end up becoming one of our family, we want to see him healed and placed with his furever home. We hate to ask, but we need help to ensure this guys survival. We wish with all of our hearts that we had the sufficient funds, but we don't. Please, if you have Anything to spare, even if it's only $1, anything would help and be greatly appreciated.
