Reverse sneezing is caused by irritation of the nasal cavity and/or larynx which an be allergy related or even caused by a nasal mite in rare cases. Yes pets can seem to be trying to vomit, but this is really them trying to scratch the irritated area. If she is doing this more frequently than comfortable with and does not respond well to offering her water during the event, then a vet visit is recommended to perhaps start her on allergy medicine and to check her for possible nasal mites. However, in most cases pets don't require any treatment for reverse sneezing episodes b/c they are infrequent and don't impede on the quality of life of the pet.
I hope that Maddie's reverse sneezing episodes resolve soon! Best wishes and take care.

Thank you for using Pet Coach! Reverse sneezes are similar to regular sneezes in that it is triggered by something that irritates the upper airway (nasal passages and nasopharynx). Occasional reverse sneezes are normal. However, since Luna is having frequent and repeated bouts of reverse sneezed, it could indicate that something more serious is triggering it. Allergies, an environmental irritant (such as perfume) or even foreign bodies (like grass) in the back of the nasal passages can cause reverse sneezes. If she continues to have bouts of reverse sneezing, or if she also develops discharge from her nose or bad breath, you should make an appointment with your veterinarian to get Luna checked out! She is lucky to have you!

My dog keeps reverse sneezing. What causes it and how can I stop it?

Hi there! Usually reverse sneezing is caused by nasal mites which are microscopic bugs that invade the nasal cavity. It could also be allergies. I’d have your vet check Molly lungs just to be safe and get her started on nasal mite medicine. Some prefer ivermectin which is oral for 3 weeks, others use different medication. I’d have your vet prescribe whatever they are comfortable with and that should clear it up. Thanks for asking us about Molly!

My dog is sneezing and wheezing. Is it reverse sneezing? What to do?

I'm wondering if Daisy might be reverse sneezing when she's making this new noise. A reverse sneeze and a sneeze can have similar causes - anything that irritates the nose and throat including allergens, upper respiratory infections, nasal foreign material like pieces of grass or even parasites can all cause sneezing and reverse sneezing. I usually don't get too concerned about either one unless there is also nasal discharge or the sneezing/reverse sneezing is occuring frequently enough that it seems to be affecting the pet's ability to rest. If so I think that your best bet is to see a vet unfortunately.

My dog is reverse sneezing, shaking, and vomiting. What's wrong?

I'm glad to hear that Sassy seems to be doing better; do I understand that correctly? It is possible that she may have been having some gastritis or an upset stomach that caused the vomiting; and perhaps some gastric reflux. If they regurgitate and the stomach contents come up to the back of the throat from reflux, that could potentially lead to some reverse sneezing and irritation in the throat. In a more serious scenario, aspiration can occur (the stomach contents from vomit or regurgitation go down into the airways) which could lead to pneumonia. You can ask your vet if an acid reducer for her stomach may be warranted, but other than that, as long as she's doing well I don't think you need to worry.

Morkie puppy reverse sneezing after drinking water, what should I do?

Hi and thanks for using Petco Pet Education Center, formerly Petcoach! Sorry to hear about Maddy. It's possible there is something in the air that is irritating her respiratory system. As long as there are no other signs (nasal or eye discharge, coughing, lethargy, decreased appetite, change in behavior, etc) then I would just monitor the situation. I know it's troubling to see her go through these episodes and if they continue or worsen, have your vet take a look at her. They may advise some antihistamines or other medications to lessen the frequency of these if they feel it will help. Good luck

My dog has reverse sneezing, vomiting, and diarrhea. What's wrong?

Reverse sneezing can be caused by allergies, upper respiratory infection, or something caught in the back of the nose or throat causing irritation. Sometimes the reverse sneeze can cause vomiting, or it is possible that some vomit got into the nasal passages and is causing irritation and thus reverse sneezing. However, I am more concerned that Benny is having vomiting and diarrhea at the same time. Small dogs can become dehydrated very quickly. Possible causes for vomiting and diarrhea include intestinal parasites, bacterial or viral infections, intestinal blockages, or other internal issues. If Benny has been having both vomiting and diarrhea for more than 24 hours, he should be seen by a vet as soon as possible.

Why is my dog dry heaving, making hiccup sounds, or reverse sneezing?

Based on your description, I’m suspicious that your dog may simply be experiencing a reverse sneeze. This is completely normal and benign. Sneezing usually occurs with irritation to the front of the nasal passages, but reverse sneezing occurs with irritation to the back of the nasal passages. Consider looking up a video of reverse sneezing to compare with your dog’s actions. If your dog is retching to vomit unproductively, isn’t eating or experiencing other problems, I recommend a trip to the vet. Feel free to post additional questions or a request a consultation if you have further questions for us. I hope this helps!

My dog had a long reverse sneeze and looked like she couldn't breathe.

Thanks for using Petco Pet Education Center, formerly Petcoach! Reverse sneezing can look quite scary at times so I understand your concern. However, thankfully this usually is benign and rarely becomes anything concerning. Most dogs just have reverse sneezing episodes every once in a while without causing any issues. If this ever seems to affect Diva in any way or if these episodes become too frequent, have her evaluated by a veterinarian for further assessment to make sure that this is not anything else more concerning. Good luck and have a great day!
