Emergency Dog Vet Bill

Today in Littleton my sisters dog was shot in her backyard and is in critical condition. We have NO idea why and who has done this heinous act on a poor innocent dog (police are involved) but she has severe internal injuries and is in the animal hospital. As of right now she has the bullet lodged in her chest cavity  that has punctured through her lung and is needing emergency surgery. The vet bill is adding up to close to $12,000 and we are asking for any help to be able to keep Hazley in emergency care and afford her vet costs. ANYTHING HELPS, and seriously thank you so much!
