Just come back from a walk and the pooch is wondering around in the kitchen - which we're due to have a new floor put in this weekend. Hubby had to remove all the skirtings to do so but has left rusty nails poking out (I didn't realise this)

, one of which the dog walked into. She reacted and moved away suddenly and half closed her eye. I've had a look and there's a small visible scratch on the surface of the eye, but she doesn't seem to be in pain at all and she's not closing the lid anymore - i.e. if I hadn't seen her do it I wouldn't have realised.
Is this something that will heal? or do I need to see the vets?
