Help Ranger heal

Ranger fell off a cliff while on a hike with my husband. He has two fractured legs, bruising on his lungs, and some fluid in his abdomen. He has been to two vets already and in the morning I take him to the third vet that will actually be able to do the surgery after they get him more stabilized. He will be in the vets care for several days then once he comes home there will be follow up appointments and possibly physical therapy.
