Nappy cob who hates going out alone ( so Ive tended not to bother riding) has arthritis in hocks. I decided to send him to vets for xrays possible joint injection etc. He is not covered for this by insurance as pre existing condition. OH says why bother, if youre not riding just let him retire, possibly on a bit of bute when needed, as its going to be expensive. However, I have recently found someone to come out with me on the odd hack. Can I justify spending a lot of cash for a once a week pootle?
