Sorry to chime in so later here---but feel free to message me if you need any more information. The eyelashes growing inward is called distichiasis. My girl Lucy had a severe case. It got so bad that she was getting abrasions on her eyes and ulcers. We eventually had to turn to surgery. I went to an eye specialist and I think the whole thing cost around $1200. The procedure was called a hotz procedure and they had to cut the top and bottom lid to change the direction of the lids so the lashes stop scratching the lenses.
If it doesn't seem to bother the pup and the eyes are healthy I would wait and see. I have to admit every once in a while I pull out an eyelash on Lucy if it looks like it is bothering her. Lucy is a doll when it comes to stuff like that so she will sit calmly and still. If your pup is squirmish or won't sit still I would let a vet pull out a stray lash.
I think your major concern right now is to watch the pup to see if this is a mild case or not. You don't want to mess around with eyes.
Good luck. Let me know if you need any help.
