Emergency Surgery for Fish the Pup

Fish is a six month old Maltese Chihuahua who loves adventuring. Sunday evening, he got so excited to see his dad that he jumped down a flight of stairs and broke his leg into four pieces. The break is right on a growth plate, and as he's only six months, he won't grow properly without immediate surgery. Fish goes into the vet on Tuesday morning, will have the surgery on Wednesday, and will be released on Thursday if we can find the funds to pay. The break is causing him intense pain, and only so much pain medication will help. 
Thank you for your help!
