MRI for Roxie

My baby Roxie has lost most use of her back legs. After X-ray showed nothing and a visit to a specialist she now needs an MRI to find out what is wrong. Most likely a disc issue and possibly surgery. The best they could do is put her in a permanent harness and put her on painkillers and steroids. I cannot afford an MRI which is $3000 plus hospitalization so I am asking please help me help my baby. Even the smallest amounts help. She is my heart and I can’t bear to watch her struggle like this. Thank you!
