Help for Foxy, Our Shiba Inu

On 1/24/18 our Shiba, Foxy got out of our yard around noon. Posting Facebook links, contacting police, animal control, and such. We searched for a few hours to no avail. We received a call from local police saying they found her on railroad tracks and looks like she had been shot. She is currently in the animal hospital being treated and they said she’ll be okay. Then they came in the room with the bill, and I thought I wouldn’t be ok. Being a disabled vet at the moment, my family is on a fixed, limited income. Any help and positive thoughts for my Foxy would be much appreciated. Thank you and God bless!
