I have had it myself and it is excruciatingly painful, it was a broken old raspberry cane that did it while I was picking.
Only once with the dogs as we are not a breed prone to it, as their eyes are not prominent or large.
In the end we had to have the third eyelid sewn across allowing it to heal underneath, with AB's applied.
There was a scar at her next eye testing but it eventually disappeared, as never mentioned at subsequent ones (and I did ask).
