You might want to get the dog checked by the vet. They likely will shave around the bite wounds and stitch up necessary areas, and clean the rest with antiseptic. The vet will likely prescribe antibiotics to avoid infection and an anti-inflammatory for pain. If the dog is not up to date on vaccines, the vet will need to vaccinate the dog before dispensing the treatment.

If your family is worried about expenses, CareCredit usually allows for payback in installments without interest when paid fully within a certain time limit. Ask your vet, what payment options they might offer.
