My dog has a swollen eye and bumps on his nose. Is it a bug bite?

Updated On September 23rd, 2025

Pet's info: Dog | Labrador Retriever | Male | neutered | 1 year old | 81 lbs

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 feel like it’s probably bug bites. I’m not sure if you can tell from the pictures. I figured I’d try asking anyway.

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 Petco Pet Education Center, formerly Petcoach.

    Hello, thank you for your question. Based on the photos and the symptoms you are describing it seems like your dog is having an allergic reaction. I would encourage you to seek veterinary care so that they can administer antihistamine or steroid medication. Hope this helps!

    This could be caused by an allergic reaction or possibly an infection. A clinical examination at your local veterinarian is essential to confirm these clinical suspicions and treat appropriately. Antibiotics may be needed.

    It could be a bacterial skin infection or an allergic dermatitis. He may need an antibiotic, anti-histamine, and/or a corticosteroid. Have your vet examine him to determine the cause and prescribe medications to treat.

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
Hello, thank you for using Boop by Petco. 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.

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

Hi there, we have a 4mth old pit/lab puppy, 2 days ago we took her to the vet for her 2nd to last round of shots. We also gave her the 1st dose of simparica yesterday morning. Later in the day we noticed her snout was swollen on the left side and don
Thank you for contacting Boop by Petco with your question about Laika and for providing pictures, they are very helpful. I see what you mean about the swelling, it is quite pronounced! This could be from a bug bite or it could be an allergic reaction. Oftentimes Benadryl is not strong enough to treat these issues, and stronger drugs like steroids may be needed. The best thing to do for her is take her into a vet immediately to get this treated. I hope this helps!

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
Thanks for using Boop by Petco! 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!

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.

My dog has a big pus filled bump that appeared on his snout right above his nose. There are a couple of smaller pimple like bumps near the site that look like whiteheads. The big bump is very lumpy and uneven, red and very pus like. Could it be a bug
Hello and welcome to Boop by Petco. Those bumps do not look like a bug bite reaction as but bite reactions are usually haired swellings in the skin. I would be worried that these are an infection or masses of a different type (benign (non-cancerous) masses or more concerningly a cancerous mass). If they popped up quickly then they are more likely infection. I would recommend not giving Benedryl, putting an e-collar on Kelso so that he can't scratch them open, and get him to a vet as soon as possible for testing and medications. Best of luck with Kelso.

My dog all of a sudden started scratching the side of his nose and now it's becoming swollen and when I touch the side of his nose it's feels like hard balls.
This is most likely due to an allergic reaction. On the muzzle this is usually happens with an insect sting, or reaction to a poisonous plant (i.e. poison oak). This is usually temporary, but can lead to a skin infection, so it's good to flush the area with cool water 2-3 times a day. Flush the area using a syringe or other dispensing device with cool water for five minutes. This may not be easy, because dogs tend to hate water getting near their face. I recommend having someone help you with holding Bob to make sure the area gets flushed well. After flushing, you can apply aloe gel to the area to provide more relief. If the swelling is not going down within two days, then I would reccomend taking him to the vet for an evaluation. It may take a week for it to look normal, but it should start to look better within a couple of days. These reactions have the potential to get worse, so if the swelling is increasing, or Bob is having trouble breathing, then be he should go to the

My dog has a swollen snout, it’s not bothering him at all. He’s still eating. He doesn’t treat it any different than if I was touching his snout when it isn’t swollen.
Hello and thank you for contacting Boop by Petco. The swelling is most likely an allergic reaction, usually from an insect bite or sting but it could be related to pollen or plant allergy. If it is not bothering Peanut at all, just monitor him at home and the swelling should disappear in less than 24hrs. If it becomes itchy and your dog stars to have fast and noisy respiration, you should take him to your local vets for an appointment.

Hello....my dog has got a swollen nose(not exactly the nose but the region below it.just above the front teeth)...i dont know if it is a bee sting or an ant bite....he is also not letting me apply ice on the area...what should i apply???? or will it
I see what you mean about Jasper's swelling! It could be from an insect's sting, but it could also be a contact allergy. If you won't let you put ice on it, I wouldn't keep trying it. Keep an eye on it tonight, and if the swelling is still present in the morning or keeps worse, take him into a vet for treatment.

My pitbull/lab’s nose is swollen suddenly & I am not sure why. Any advice on what it could be from?
Hello and welcome to Boop by Petco. It looks like Gunther either got a bump on the nose and that is a bit of a bruise, or more likely was either bitten or stung by an insect. I would recommend monitoring it closely. If you notice the muzzle/around the eyes/jaw/lips/ears starting to swell, or if you notice hives on Gunther, then I would get him to a vet right away for a couple injections to stop the allergic reaction. Otherwise, I would just monitor the bump. If it grows at all, or has any discharge, or doesn't go away in 2 days, then I would have it looked at by a vet. Best of luck with Gunther.
