Hi Sabby and all, you did 'heighten' my awareness of the possiblity, yes I was a little scared, but it also made me have information to work from. I spoke to 2 seperate vets, and they both implied they expect to find Todo has some form or CM / SM due to the symtoms and pains. The vet who did the MRI did mention as an option that is could be degenrated discs, but this was 'extremely unlikely'. So thank you for bring this to my attention, we have just had our first night with Todo back with us, he is a little sore ( huge scar ) but fingers crossed he will make a rapid full recovery, he has to go back to get stitches and other test results in two weeks. Thanks again all
