PLEASE HELP MY PUPPY CUDI (Thank you)

This is not just any dog, this little guy is truly my best friend. I have never met a dog as sweet and happy as Cudi. Today out of the blue he basically lost all feeling in his legs. If he doesn't get surgery in the next 5 hours, he will have to be put down. I cant lose my dog. I love this dog more than anything he's my family. Please help if you can! Thank you so much!
