Our charlie also has problems with his back diagnosed as IVDD (Intervertebral Degenerative disk disease) which I have since discovered cockers are one of a few breeds which are pre-disposed to. He was paralysed in his back legs 2 years ago when 2 of the disks in his spine exploded. We 2 thanked god for Pet Insurance then as he needed spinal surgery done by a neuro surgeon at Glasgow University Vet School, which ended up costing £2,500. After a lot of rehab and physio we got him mobile again, he still has a weakness in his back legs and doesnt do stairs or is not allowed to jump on and off the furniture any more, he is easily tired. But he and we have made adjustments to cope with this and he is still our boy.
