Awww, thanks everyone. We are just back, the vet said it was indeed cherry eye, a prolapse of the tear gland or something near? Anyway, he managed to pop it back in, and hopefully it'll stay in, which the vet said is what we want, otherwise an op if it pops again.
He's got anti inflammatory eye drops, and we will take it easy today, not too much exertion apparently :roll: don't think a cocker puppy will manage that somehow!
