Help Dottie!

Dottie is an amazing dog. She makes everyone and everything around her brighter. There aren't even enough words to describe how amazing she is, so I won't try. But, if you've met her, you know.
Last March, suddenly Dottie began screaming out in pain, having difficulty moving and was not herself. The vet determined she had a slipped disc and put her on a round of medicine, laser therapy and strict rest. After 6 weeks, she appeared better. 
This past January, the symptoms came back, but much more aggressively. Since January, we have done laser therapy, medicine and rest. Unfortunately this time, she has not responded to treatment and is continuing to worsen. Dottie has also begun having panic attacks due to the pain, and has had bouts of pain more frequently.
Most recently, I brought her to a neurologist to have a series of tests done to determine exactly what is going on. And to also determine next steps. They determined she has a very bad herniated disc in her neck, coupled with issues in her back. The appointment and testing were over $4,000, and that does NOT include any type of treatment. 
Dottie is in need of specialized and expensive veterinary care. After laser therapy, months of management and seeing the neurologist, I am left worried, and heartbroken. I am not the type of person to ask others for help, but Dottie is my whole world and I would do anything to make her feel better.
If you can help Dottie in any way, I would truly appreciate it. Please help brighten Dottie's world, like she brightens it for everyone around her.
