It sounds like you need a lawyer and you'd have to take it up with the AVMA (American Veterinary Medical Association).
Another vet won't touch it because (has nothing to do with brotherhood) they weren't there. They can not prove what happened at the hospital or in your home. All vets practice medicine differently too.
I don't know your case and haven't 'read' anything. I am just going by what you wrote in the post.
Did you receive and sign a paper for aftercare?
Also, did you give the medicine exactly and on a timely manner? Clean the ears as stated in your consult (thinking you received a consult?) You'd have to prove that you did every thing correctly and you'd have to prove neglect on the veterinarians part. Very hard to do since the dog was in your care for the past 7 days. What did the ears look like when you left the hospital? When do you feel the pup started to get sick? Did you call the vet right away? What did the vet recommend to do? You'll have to answer these questions factually and not opinion-ally.
I am assuming the body has been disposed of, so a necropsy can not be done to help your case. And a case like this can take years and is costly. You may not win in the end.
Unfortunately, we all know that during, and after surgery, comes with risk. Sepsis can happen and it is due to infection/inflammation in the blood.
I am sorry for your loss and I wish you well.
