lately one of my cockers eyes has been running a little causing his white fur to look a bit red along thr side of his nose . should i take him to the vet again ,as he has been once and he said it was ok.Thank you Sally

I would, eyes are not something you want to be casual about.  Perhaps a different vet could give you another insight?  Not saying the one you saw is bad, but different vets specialise in different things.

I'd take him back to your vets, you have to be extra careful with eyes in cockers.   Hope everythings OK.
