My dog has a bump on his eyelid. Is it a bite or allergic reaction?

Updated On September 23rd, 2025

Pet's info: Dog | Mixed Breed | Male | neutered | 1 year and 9 months old | 15 lbs

I just noticed a bump above my dog's eye. It is kind of on his eyelid. He's a Boston terrier/pug mix. He doesn't seem to be bothered by it. He had been outside for about 15min when I noticed it and there are a lot of bugs flying around. Could it just be he was stung by something or having an allergic reaction? We didn't notice it yesterday or even this morning.

Hello, thank you for using Petco Pet Education Center, formerly Petcoach. It very definitely can be an allergic reaction to a sting or bite. If it is not bothering him, then there is probably not too much to worry about, You can apply a cold compress to the area ( a bag of frozen peas wrapped in a towel works well ) for 5-10 minutes every hour or so, but if he begins whining, scratching his face, or pawing at his eyes, you may need to run him in to your vet for steroids, &/or antihistamines. Hopefully, it will start to go down soon. Take care.

    It could be local infection or inflammation. Monitor for rapid change or growth. If he is pawing at it or rubbing, place an e-collar (cone) on him and have it examined in person by your veterinarian.

    Thanks for using Petco Pet Education Center, formerly Petcoach! While a growth is possible, this is actually likely just a bit of inflammation possibly due to trauma. I would recommend you continue to monitor him closely for now. However, if this does not improve or you notice any squinting or eye discharge, have him evaluated by a veterinarian for further assessment and treatment. Best of luck!

    Thanks for using Petco Pet Education Center, formerly Petcoach! This looks fairly small and mild. This could have been a bug bite or even something like due to irritation. I would continue to monitor him for now. If this gets any larger or starts bothering him, have him evaluated by a veterinarian for further assessment and treatment. Otherwise, this is likely going to go away on its own. Best of luck!

This bump appeared under my dog’s eyelid a day ago, seemingly overnight. It’s soft to the touch and very much looks like a bug bite. My dog doesn’t scratch it, it doesn’t seem to bother him in any way. Should I be worried about it. He is a 9 year ol

Hi! My 4 year old terrier mix developed this bump underneath his left eye within the last 24 hours. It doesn’t seem to bother him or affect his vision. Should we see our vet immediately? Thank you!
Hi there and thank you for using Boop by Petco to address your concern. Based on the photo, the swelling could be from a number of things. This could be from an insect bite / sting, an infection or a cyst. Since this just showed up in the last 24 hours, the likelihood of this being a cyst is small. I would say this is more likely from an insect bite / sting. I would recommend applying a warm compress to the area (warm water washcloth) several times a day and consider giving Benadryl. Here is an article on Benadryl dosing you can use as a guideline. I hope this helps! If it appears to be worsening or Giannis' vision appears to be affected, I would get him to a veterinarian right away to be checked out. https://www.petcoach.co/pet-medication/benadryl

I dont know what’s going on with my dog’s eye , He was perfectly fine an hour ago and all of a sudden he has these bumps on his right eye , they don’t necessarily bother him , but he does get irritated when i try to touch the area or whenever i try t
It could be allergic reaction - it often starts at the eye(s) and face in dogs. You should apply a cold compress on the eye for a few minutes. Repeat that for 3-4 times. The swelling should slowly go down and dissapear in 8-10 hrs but if it is getting worse, or he wants to scratch the eye, please take Bleu to your local vets.

Hi, I noticed our dog has some swelling under his eye. I’m wondering if it’s from a horse fly or a bee or something. My husband isn’t sure if he would have hit it something when he was playing. About an hour later, I noticed bumps on his nose. So I f
Hello. A localized swelling like this in a relatively young dog is probably just some kind of allergic reaction. I agree with you that it is probably from an insect sting or bite. If Buddy will allow it, you can apply a cool compress or an ice cube wrapped in a wash cloth for as long as he will tolerate it. If it is not significantly down by tomorrow, you may want your vet to take a look, but there does not seem to be anything very worrisome about this. Just watch for any changes over the rest of the evening. Thanks for using Boop by Petco.

My dog has a swollen upper eye lid (very small swell) is there anything i can do or should i take her to the vet.
Thanks for using Boop by Petco. A picture might be helpful in getting you a more accurate response. If it looks like a single lump on the very edge of the eyelid, it could be a benign eyelid cyst or beingn tumor. These we often leave alone unless they bother the surface of the eye or they are getting large. If it is not very defined swelling (just a general “puffiness”) it could be the beginnings of an allergic reaction, bug bite, etc. You can try some Benedryl just in case but if the swelling gets worse throughout the day, or you see any other signs of allergic reaction (vomiting, diarrhea, collapse, hives), you need to head to the vet right Immediately as severe allergic reactions can be life-threatening. Best wishes to you and your pup!

My 18 mo old mixed boxer has a “pimple like” bump that appeared on her lower eyelid. She is fine with me touching it, it doesn’t seem to bother her. But it has increased in size in the last 2-3 weeks.
The most common reason that we will see white bumps develop on the edge of the eyelid is something called a chalazion. This is similar to a stye, but is not generally inflamed or painful. Sometimes we will use antibiotic eye drops or ointment if the area is red, but they will normally resolve on their own (but this can sometimes take a couple of months). Sometimes using a warm washcloth on the area for a few minutes twice a day can help, but some dogs do not tolerate this well. If the area continues to get larger, appears red or irritated, or does not resolve in a couple of months, I would certainly recommend having your veterinarian examine it. Good luck! I hope that was helpful. Thanks for using Boop by Petco.

My dog had a red bump on her face last summer. It showed up quickly, and was gone in three or so days before I had time to take her to the vet.. Now she has it again right by her eye near the tear duct. It wasn't there this morning, like last time it
This could be an insect bite, a blockage of a tear duct (though I would expect that swelling to be more on the lower lid), an allergic reaction, a bacterial infection, an ingrown hair follicle, and more. If your dog seems comfortable, you can try applying a cool compress to the area if it appears itchy/painful. If it doesn't seem itchy or uncomfortable or warm you could also try a warm compress and then gently massaging the area in case it is blockage of a tear duct. If the swelling is still there tomorrow, I would schedule and appointment for your vet to check it out.

This morning I noticed this bump on my puppy's eye lid im thinking its just a bug bite but want to be sure
Thank you for contacting Boop by Petco with your question about Lakota and for providing a picture, it's very helpful. It could be a bug bite but it could be a stye. Take a warm compress, and apply it to the area for five minutes at a time a couple of times a day to see if that helps it drain. If it gets bigger, starts to bother her, doesn't go down in a day or two, or appears infected, have her seen by a vet. I hope this helps!

Why does my dog has a little bump on her eye?
Hi, thanks for using Boop by Petco! Poor Daisy! From your picture, it appears as though Daisy's eye lid is swollen in corner (by her nose). This can be from an infection or an allergic reaction. If she is squinting her eye, keeping it closed, rubbing it, the eye is producing green-yellow discharge I recommend she be seen today. If not make an appointment to have her seen Monday. Also read this article for information on Benadryl https://www.petcoach.co/canigive/dog/benadryl/ I hope this helps and I wish Daisy a speedy recovery!
