Q: Why can't my Great Dane see??

We have an 8 year old Great Dane, we recently noticed that her eyes were kind of cloudy so we took her to the vet. The vet tested her eyes and told us that she had ulcers in her eyes. So she gave us some eye drops to fix it, and had us bring her back 2 weeks later to check up on her eyes. They have gotten worse! What in the world is going on with out Great Dane? Now she has gone blind!! She can't see anything! She runs into everything.. What can we do??? She's on thyroid medicine (Thyrosyn) I think that's how you spell it. Is there anyway that her not being able to see is a side effect to the thyroid medicine?? Please help me!!

Hypothyroidism itself can cause blindness, but the medication does not. Danes that carry the merle gene, like the Harlequins, carry the gene for blindness (and deafness), but they're born that way. It's typically disease that causes them to go blind later on. Keratitis, which is basically cloudy eyes, can lead to partial or complete blindness. There are several forms of Keratitis. Some forms are progressive and incurable, other forms respond really well to topical corticosteroids. Infectious Keratitis is caused by a bacterial infection and can be treated with antibiotics. Danes are prone to glaucoma but I don't think that causes clouding of the eye. It's just very painful. Cataracts, which Danes are also prone to, will cause clouding of the eye and lead to blindness. I would definitely get her back to the vet for a full workup. All eye issues like that can only be diagnosed and treated by the vet. Some eye conditions can be reversed if treated before they cause permanent damage. If you feel this vet isn't taking the problem seriously, get a second opinion. Good luck!

This is not an affect of thyriode medicine that I know of but I have a friend she is a dog trainer and knows dog breeds well alot of Great Danes lose their sight when they get older but becoming blind can be a sign of diabetes in dogs so I would defenitly have the vet check her blood sugar the next time you take her in. Also my friend had a dane she adopted him as a pup the owner was gonna just put him down cause he was born blind and deaf she had him until he was 10 but they are great dogs. Also Dogs use their nose more than their eyes Skitters has cloudy eyes and she is almost entirely blind but she is not running into things and I know that my friends dane Gorge never ran to anything either for one thing since dogs use their noses you might try setting up stuff with diffrent scents in every room like candles say put a melon candle in the living room and then a rose candle in the kitchen just don't put the same scent in every room or she may get confused this just might help also use rubber gaurds to put on sharp corners that they use for people with toddlers so that if she runs into them she won't get hurt other than that I am not sure what else you can do good luck!
