Why is my dog's red, irritated eyelid still crusty after Benadryl?

Updated on September 23rd, 2025

Pet's info: Dog | Husky | Male | neutered | 11 years and 7 months old | 56 lbs

My dog has a red irritated upper eyelid. It seems to crust after a while. I gave him some Benadryl hoping to bring down the swelling, thinking it was an allergic reaction and it seemed to help somewhat but now its back.

He could have a bacterial infection and need an antibiotic to treat. Since the Benadryl is not working, he should be examined by a vet for treatment. Your vet can prescribe an antibiotic and an anti-inflammatory, if needed, to treat.

    This looks like conjunctivitis. The benadryl should reduce the itching but I recommend a veterinary exam to check for a corneal ulcer and get eye medication to reduce the swelling and prevent infection. I always recommend an exam and treatment with eye problems since they can sometimes cause permanent vision problems.
