Help Gus walk again

My 9 week old puppy, Gustav, fell down the stairs and broke his leg. Due to his age and size, he may need multiple surgeries in order to keep his leg. He’s the sweetest little boy, full of love, happiness and razor sharp puppy teeth. If you know anything about me, you’d know that my dogs are my babies, so any help is truly appreciated and means the world to me and Gus Gus
