Why is my dog's eyelid swollen, but he's acting completely normal?

Updated on September 23rd, 2025

Pet's info: Dog | Mixed Breed | Male | neutered | 3 years and 9 months old

Dogs eyelid is swollen on top. He’s acting fine and wanting to play like normal. And he isn’t rubbing at it or anything. Just looks bad.

Hello. This could be some type of allergic reaction. Apply a warm compress to the area twice a day for 10-15 minutes at a time. You will need to keep the water quite warm, but not uncomfortable. If the swelling does not go down by tomorrow, please make an appointment to see your veterinarian on Monday. Hopefully, the swelling will resolve by then. Thanks for using Petco Pet Education Center, formerly Petcoach.

    Oh my, poor Lamar! I can certainly see the prominent swellings of both of his eyelids. One of the most common causes of eyelid swelling is from an allergic reaction. The tricky part with allergic reactions is that we often aren't able to figure out the trigger - whether he may be reacting to an insect or spider bite, pollens outside, or countless other things. However, since it looks as though Lamar is missing a good bit of hair around his eyelids (although this could also be pigment change and some glare in the picture), other possible causes could be infectious issues, like mange. Certainly other skin lesions or itching would make this scenario more likely. Since it's most concerning that he's possibly experiencing an allergic reaction with swelling on his face, you really should take him to an emergency vet right away for evaluation and treatment. Some allergic reactions can progress to anaphylaxis, which can cause severe breathing difficulties. I hope that he's feeling better soon!
