How to spot eye problems in your dog

The pupil is a key part of your dog's eyes, just like ours. It's the black circle in the centre. Sometimes, especially if your dog has dark eyes, it can be tricky to spot. Generally, the lighter the eye colour, the easier it is to see the pupil.

Your dog's pupils and daylight

It's completely normal for your dog's pupils to change size throughout the day. However, both pupils should always be the same size. Pupil size changes depending on the light – they're usually small in bright light and larger in dimmer conditions.

Unequal pupil sizes

If you notice that your dog's pupils are different sizes, it could mean they have an eye problem. If your dog is blinking one or both eyes, that's also a sign something's wrong. If you spot unequal pupil sizes or excessive blinking, always contact a vet for an eye examination. If you're unsure, you can always chat to our digital vet service – a perk for all Lassie customers.

Remember, it's natural for pupils to get smaller in bright light. So, if you're checking your dog's eyes and the light hits them differently, it might look like the pupils are different sizes. Always compare them when both eyes are under the same lighting conditions.

Eye injuries in dogs should always be taken seriously. If you suspect your dog has an eye problem, please contact a vet immediately.
