My 6 month old CKCS, Rusty is deaf in both ears. He is due to have an MRI scan on Friday to check for Arnold Chiari syndrome. He does scratch his neck quite alot but does not show any symtoms of pain. I'm really feeling lost about what the future might hold. Very little I have read links the deafness with Chiari so I am confused as to why he is being sent for the scan.
