My dog's third eyelid is always visible. Is this normal or a concern?

Updated On September 23rd, 2025

Pet's info: Dog | Mixed Breed Medium (23 - 60lb) | Male | unneutered | 4 months and 29 days old

I've read that if a dogs third eyelid is showing then it shows there is something wrong. I've had him for about a month and I think the eyelid has always been visible. I don't want to take him to the vets if it's nothing to worry about. It doesn't seem to be bothering him and his eyes are normal apart from that, not swollen or itchy.

It can be normal for the third eyelid to be slightly visible in some dogs, due to the shape of their faces and skull bones. In the photo, Ziggy's eyes look normal to me. If this is how he has always looked, and he does not have any other signs of an eye problem such as redness, squinting, or discharge, I would say that this is probably normal for him and not a reason for concern :)
