My Shih Tzu puppy has a blue ring around its eye. Is this normal?

HI, thanks for using Petco Pet Education Center, formerly Petcoach! If you are referring to the blue line around the brown iris color and the white of his eye, it may be a deposit of cholesterol or normal for a puppy Rocky's age. If he isn't squinting or rubbing his eyes then have your Vet take a closer look at his next puppy visit. Cholesterol deposits usually are not harmful. I hope this helps!

Hello. It appears that Panda may have bruised the eye. It is not uncommon for the dog breeds with protruding globes to accidentally get bumped in the eye. Usually, the redness will go away in a few days, but if the area does not clear or seems to be getting worse, or you notice any discharge from the eye, enlargement to the globe, unequal pupils or anything else that concerns you, please see your veterinarian as soon as convenient. Otherwise, just observe things for a couple of days. Thanks for using Petco Pet Education Center, formerly Petcoach.

Heterochromia in dogs means the dog has two different colored eyes. This is usually no cause for concern unless there is an underlying medical condition. Luna's eyes are the same color. The blue ring you are seeing on or near the margin between Luna's iris (the colored part of the eye) and the sclera (white part) is likely no cause for concern in the absence of other symptoms (redness, swelling discharge, pawing at the eye/face). https://www.petcoach.co/dog/condition/heterochromia/

Puppies vision develops gradually between 2 - 7 weeks of age and it is very hard to tell at this age how this will improve, The eyes do appear a little hazy and I recommend a vet check to rule out any infectious or inflammatory cause which may improve with treatment. Conjunctivitis, ulcers and certain viral infections can cause 'blue eye' and a full health check is recommended

This could be an inflammation of the sclera (episcleritis). At this time this does not look very dramatic or like an emergency as I cannot see other swelling which would point to more serious diseases such as glaucoma or an underlying autoimmune disease, however I would make an appointment with a veterinarian for an eye exam soon. It is not possible to diagnose this from a photo, and would need a proper eye exam. The cause of episcleritis (superficial inflammation of the sclera) or scleritis (full thickness inflammation of the sclera) is unknown, however toxins, autoimmune disorders and toxoplasmosis are accepted causes, In severe cases the vet may want to take a biopsy under anesthesia to distinguish between a mass and inflammatory tissue. Treatment may be necessary and would consist of corticosteroids and/or other immunosuppressants.

This could be a normal pigment change with age. If you could post a picture that may help identify what exactly is going on. However if his eye is normal, he's not squinting, no tearing, no discharge then it's likely a normal change for him.

Thank you for submitting your question regarding Symphony. She may have a condition known as cherry eye where the third eyelid becomes prolapsed. She will need to see her veterinarian to know for sure. If this case, surgery can be performed to replace the gland. I hope this information helps!
