MRI IVDD French bulldog spine vet treatment

Hi this is Mabel she is insured. However sadly she was born with a front leg that knuckles and deformed spine and other legs. I rescued her as I fell in love with her beautiful eyes and could not leave her. She just wants to love and be loved. Sadly she was screaming in pain and has been to the vets and is on medication but I cannot afford £10k for an MRI and it is not covered by the insurance as it is pre existing. Mabel is family and we love her. She is currently not able to walk and is being syringed water and food and she cries when she does the toilet she can’t move so just does it on the puppy pads. It is heartbreaking to see her this way so any help would be appreciated. Thank you so much for reading this lots of love Mabel
