Loki's surgery

Loki has damage the vertabrae that controls his back legs and using the bathroom. Without surgery Loki will have to be put down in a week. He can not survive without this surgery. I am asking all my friends and family to please help us save our dog. Any donation is welcomed. We rescued Loki from the pound after being returned 4 times. We have fallen in love with him he is only 4 and half years old. Bob and I never ask anyone for help, but we are asking you now. His surgery is in Pittsburgh where they have an MRI for animals. They do not take payments and we just dont have that kind of money in a weeks time . Again any and all help is greatly appreciated. Thank you.
