At first your puppy’s eyes will be a milky grey/blue colour – don’t be alarmed, this is completely normal and will clear with time. Their eyes won’t actually fully mature until they’re between four and five weeks old.
As their eyes mature, they develop the ‘tapetum lucidum’, a layer of tissue behind the retina (the back of the eyeball) that helps dogs see at night – it’s also what gives them that green/yellow glow when you see their eyes reflected in headlights or with a camera flash.
When to contact your vet
In the majority of cases, puppies’ eyes open naturally by themselves without any assistance from you or a vet, but you should still be monitoring their progress along the way. Things you should be on the lookout for include:
- Swelling or bulging beneath the eyelid: this could be a sign of an infection
- Pus or discharge from around the eyes: again, this could be a sign of an infection
- If they don’t open their eyes by the time they’re two weeks old. If this date passes and their eyes still aren’t open, it could be a sign of a developmental problem
If you notice any of the above signs, contact your vet straight away. Puppies’ eyes are so delicate and getting the correct care as early as possible can make all the difference in ensuring their eyes are not impacted later on in life.
