Why is my dog's swollen eye bleeding after a possible sting?

Updated On September 23rd, 2025

Pet's info: Dog | Labrador Retriever | Male | neutered | 5 years and 4 months old | 125 lbs

Under Eye was swollen yesterday gave Benadryl thinking it was a sting because dog likes to chase flies/bees. This morning eye has blood in it? Could this just be discharge from swell spot? Dog is a lab and his eyes have been normal goopy from the smoke we've had from the fires in our state.

I am so sorry to hear that Moose is experiencing these problems with his eye. Thank you for providing an excellent picture, it seems swollen red and has discharge. Because of the sudden nature of the presentation, I would be concerned that Moose has suffered a corneal ulceration or has a foreign body lodged in his eye lid. Start by placing an e-collar or cone on Moose to prevent scratching or rubbing. If the eye is infected it is likely painful, this will prompt Mosoe to scratch or rub his eye. However, this could inflict further damage, infection or even an ulceration. Because eye concerns with dogs, such as infections, corneal ulcerations, cataracts and glaucoma, can progress rapidly, I would have him examined by your veterinarian to diagnose the issue. The precise medication can then be dispensed by your veterinarian. Please do not attempt to treat an eye infection at home with any over the counter medications, drops or ointments. This can lead to permanent damage and unnecessary pain or discomfort. I hope this answer was helpful and that Moose feels better soon. Warmest regards to you both!
