What causes my dog's bloodshot, cloudy, watering, and itchy eyes?

Updated On September 23rd, 2025

Pet's info: Dog | Mixed Breed Small (up to 22lb) | Male | neutered | 7 years and 9 months old | 18 lbs

Baxter, my yorkie/Rat terrier mix, has had bloodshot eyes for the past two days. He has been squinting, blinking, and trying to scratch at them, and I've noticed that his eyes are a bit cloudy and are watering. I'm definitely willing to take him to the vet! I just need some guidance on what might be causing it.

It's most likely an eye infection, possibly conjunctivitis. Taking him to the vet now is great, before he damages the eye teslf by rubbing and scratching. Your vet will do an ophthalmic exam, part of which may be putting a dye in his eyes and examining them under a black light to look for scratches on his cornea. Based of the results of the exam, it will allow your vet to know just what is going on and how best to treat it.

    Even if from your description it sounds like a conjunctivitis, I would recommend to take Blaze to your veterinarian for a check up as sometimes more severe corneal or in general eye injury could be present in these cases. The fact that the eyes are potentially itchy could suggest the presence either of an infection or an allergy.

    I am so sorry to see that she is so uncomfortable. Red eyes can be caused by allergic conjunctivitis, infectious conjunctivitis, ulcers or scratches to the cornea, and uveitis. In her age glaucoma could be very rare. I would encourage you to have her evaluated by your veterinarian soon. In the meantime using a cool water compress to the eyes every few hours may bring some comfort until she can be seen by a veterinarian for an ocular exam and diagnosis. Best of luck and I hope she improves soon. Thank you for using Pet Coach.

    If he is squinting or his eyes seem painful you should see a veterinarian today to make sure he doesn't have scratches on his eyes (corneal abrasions). If the white part of his eyes are red with a small amount of discharge he could have allergic or infectious conjunctivitis, which could probably wait until tomorrow for treatment. I would not recommend using any eye washes or drops until you can see a vet.
