Help Archer get his leg fixed

On Sunday morning as we were getting ready for church Archer, our family dog, got loose from the back yard and was struck by a car. We were able to take him to see a vet that morning and they took x-rays and gave antibotics and pain meds for him. Today we got the call from the Vet Surgeon. Archer will need to have a plate and screws put in his left leg. The break is a compound fracture that can't be healed without surgery. Unfortunately we don't have the money to get this surgery done.  Please if you can help us out. My family loves this dog and we have scheduled the surgery Tuesday. Surgeon said the sooner the better. The surgery with medication and all the necessary care materials will be an expense we hadn't budgeted. Thank you in advance and I will keep everyone posted.
