We took kissespup for her first beach trip last weekend and on Monday one eye was producing green gunk. I cleaned it and swilled it with water every day. By today her eye is no longer red and no extra gunk, normal eye bogies normal colour. Based on my experience of sand in eyes in humans I didn't see the need for the vet but would have gone if pup was otherwise under the weather or if eye hadn't improved by now. Just wanted to ask if I made the right assumption
