My dog's nostril is swollen on one side. What could be causing this?

Hello and thank you for contacting Petco Pet Education Center, formerly Petcoach. 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.

Thanks for using Petco Pet Education Center, formerly Petcoach! This is most likely an allergic reaction. He needs to see a veterinarian as soon as possible. This is typically treated with steroids and anti-histamine medications and they do well if treated promptly. Have a good night!

I am sorry to hear about Pepper! A swollen face can be caused by a variety of issues, including an allergic reaction, a bite from an insect, or an abscessed tooth to name a few. These are all treated with different medications, so it is recommended to bring Pepper in to the vet to examine her to determine what is causing the swelling and how best to treat her. If the swelling is increasing in size or she is struggling to breath it is a medical emergency and she should be seen immediately.

Thank you for contacting Petco Pet Education Center, formerly Petcoach with your question. This could be an allergic reaction is there is no sign of trauma. The concern here is that the swelling is spreading, and it could get big enough to obstruct her breathing. I think it's best to have her seen by a vet now to get this treated. I hope this helps.

Roxie may have gotten bitten or stung by something to cause that location reaction which can be painful. An infected tooth can also cause a swelling in the area. If she is eating and drinking well and acting normal otherwise, then keep her quiet tonight and have your vet check for dental disease tomorrow. If she is lethargic and the swelling gets worse, than I would have her check at an ER tonight

Thank you for contacting Petco Pet Education Center, formerly Petcoach with your question about Sasha. Poor girl. She may have injured it, have an infection, a growth in it, or is suffering from an allergic reaction. She will have to see a vet for this. If she can breathe ok, isn't lethargic, and is otherwise acting normally, it can wait until the morning. If she is struggling to breathe, is lethargic, or acting differently, take her into an ER vet now. I hope this helps!

Thanks for using Petco Pet Education Center, formerly Petcoach! Based on the swelling's location, this is possibly due to a tooth root abscess. This is something your veterinarian could check for on an examination and treat if confirmed. This is something that is treated with local therapy including drainage, debridement and antibiotics. Good luck and have a great day!
