Bleeding hearts of the world unite!

We found this puppy on the side of the road. He had been hit by a car and was being eaten alive by ants. He was estimated to be on the side of the road for more than 24 hours!! He has a broken femur/tibia/fibula, among other injuries/lacerations, and needs surgery. Amputation is the cheapest option, but if we receive more funds than asking we may be able to save his leg! Otherwise, we have been recommended euthanization. He is a sweet SWEET puppy and this is my last resort to help him. Please, please! Anything helps! More photos to come once we get him home!
