Saving Maverick

Our 7th month old German Shepard family pet Maverick was hit by a car. His leg is broken in several places and may have lung contusions. We took him to the animal hospital. They gave him pain medicine, put him on oxygen and a catheter in place. We just had enough money to take care of this. If he survives the next 24 hours he will need surgery to save the leg. It will cost 2500.00 to 3500.00 just to do the surgery. This will not include his meds and aftercare. We have 3 young boys that love Maverick like they love each other. Please help us save our precious family pet !
