My Cocker , Topaz is nearly 13 and I have suspected she has had failing eyesight for a little while, but suddenly it is more noticeable, seems to have happened in just a few weeks, anyone else come across this, she doesnt have grey eyes and I can see any excessive blueyness? Is there anything it could be that is actually treatable, she gets very stressed at the vet, so dont want to take her unless there is a chance they can help
