Help for Clifford

I set this page up for this sweet boy, Clifford, who is my sister and brother-in-laws puppy. Cliff is not even one year old yet, and just last week he was sent to the emergency vet because he wasn’t walking right. Today my sister and her fiancé found out he likely has Discospondylitis, which is an infection in the intervertebral disc space. This requires EXTENSIVE testing and blood work to figure out the type of bacteria is causing this horrible infection. Then will require 4 to 9 months of intensive antibiotic treatments.
He is currently in the hospital undergoing many tests, an X-ray of his spine and a CT scan.
This is so heart breaking to watch a puppy go through,  as he can no longer walk on his own.
My sister and her fiancé have their wedding coming up in just 10 days so this timing for them is extra difficult.
Anything that you can do to help would be so appreciated.
