When Voltaire was a puppy he used to have a little light coloured bobble of flesh appear in the corner of his eye after he'd played a lot. It used to disappear back under when he slept and then reappear when he played again. Until it didn't seem to go away at all. It didn't bother him in the least by the way. I took him to the vet who explained it was a pretty common thing with dogs who have "saggy type eyes" - one of the tear duct glands pops out. He did a small op to snip it out and put in a couple of stitches. A month or so later - same thing with the other eye - same op, and since then no problems at all. That was 2 years ago. My brother in laws dog (not in the least related) had the same problem. Just wanted to post this in case anyone has the problem and doesn't know what it is...
