Who can resist a new puppy? Those little paws, that special puppy smell, the way their eyes are squeezed tightly shut as they fall over each other as they’re playing. But did you know that puppies' eyes remain closed for a few weeks after they’re born?
They’re completely closed off to the rest of the world, even their ears are sealed for the first 13 – 17 days, so they must rely on smell, touch, and pheromones, the chemicals that animals rely on to communicate with each other.
Eye contact is very important when building relationships, it’s how human mothers bond with their babies as it increases oxytocin levels. Oxytocin is the hormone associated with maternal bonding and studies have shown that dogs experience a 130% increase in the hormone and humans a whopping 300%, when they look into each other's eyes.
So, what do we need to know about this crucial part of puppy development?
Why are puppies born with their eyes closed?
A puppy’s central nervous system isn’t complete when they’re born; their brain hasn’t developed yet, and the optic nerve has yet to be formed.
Mammals are often born early, before their brains are fully developed, to enable the adult to leave them in a safe place while they hunt and provide for them.
If the eyes stay shut they can develop and grow without the risk of infection or damage by foreign objects, it also protects their eyes from bright light.
When do they open their eyes?
This can vary between different dogs as well as between breeds, for example, the bigger the breed, the sooner they open their eyes, and a Cocker Spaniel puppy will open its eyes before a Fox Terrier, but in general, puppies open their eyes between 10 – 14 days.
They don’t always open their eyes at the same time either; they might open one eye one day, then the next a couple of days later. The most important thing is that it happens naturally and is never forced.
What can they see?
It can take 3 – 4 weeks for a puppy’s vision to develop, but even then they can only detect movement, and everything is still blurry. Their eyes are also still very sensitive, so they need to be kept away from bright lights.
Their vision improves over the next few weeks, and by 8 weeks old their level of vision should be the same as an adult dog.
When should you be worried?
Puppies need careful monitoring as it’s important to deal with any issues as soon as they develop, so keep an eye out for bulging, swollen eyelids, or pus/discharge as this could be a sign of infection and will need looking at by a vet.
If your puppy is three weeks old and still hasn’t opened their eyes, it could mean there are developmental issues. It could just be that the light is too bright, but it’s always worth getting them checked out by a professional.
