My dog's green nasal discharge returned from one nostril. What's next?

This could be a fungal infection or an antibiotic resistant bacterial infection. If bacterial and fungal cultures have not yet been performed, I would recommend that you request them. I would also suggest a consultation with a veterinary internist for a rhinoscopy with possible biopsies. You can find one in your area on www.acvim.org.

This must be really frustrating for you! Since four different antibiotics did not improve Skye's condition, I would think that her nasal discharge is either not due to bacterial causes or is a highly antibiotic resistant bacterium. Other causes of nasal discharge can include fungal infections, viruses, masses in the nasal cavity, presence of foreign material (I once saw carpet fibers cause nasal issues!), etc. Unfortunately, I don't think there are any at home remedies that will help Skye. At this point, I would recommend having your vet recheck her and consider x-rays or a nasal culture as the next diagnostic steps.

I apologize for the delay in answering your question, and I am so sorry that Carlos is having problems. It’s possible that he’s got rhinitis, which can be caused by an allergic type reaction, an infection, or even an auto-immune type condition where the nasal passages become inflamed for no reason. A foreign body (such as a grass seed) would also be possible, as would a nasal tumor. A rhinoscopy (scope of the nose) and biopsy may be needed for a diagnosis and to determine the best treatments. Follow up with your vet to discuss the recurrence of the problem, and discuss the best way to move forward. http://download.skyscape.com/download/ota/5mvetcf5/documents/pdf/rhinitis_and_sinusitis.pdf Thank you for asking PetCoach!

Poor Tersk! Nasal discharge with blood is always very concerning in dogs, and is not likely to be due to a simple cold. I would be concerned about a possible nasal tumor, a fungal infection, or even a foreign body such as a foxtail or a blade of grass stuck in the nasal cavity. These problems generally do not show up on x-rays or blood work, so I agree with your veterinarian - rhinoscopy would be the next step to try and get a diagnosis.

Poor Roxy! I can definitely see the dry discharge from both nostrils. You’re right in saying that this can be caused by an upper respiratory infection. In most cases these infections cannot be transmitted to people or from people to dogs. These are very common in dogs, and can easily be treated with antibiotics prescribed by a veterinarian. Unfortunately, nasal discharge can be caused by several other diseases such as a nasal foreign body or mass, or even pneumonia. Your vet can do some blood work and x-rays to determine the exact cause of Roxy’s nasal discharge. You should have her seen immediately if she begins acting lethargic, loses her appetite, or you believe she’s having trouble breathing.

Left nasal cavity seems full of discharge and bone seems affected as well (so whatever is inside is causing bone erosion as well). It is not possible to determine what it is specifically from the CT images and a further investigation is unfortunately needed. Was rhinoscopy performed? was a biopsy taken? Otherwise aggressive treatment for fungal infection is required (not only oral treatment but often ''flush'' of the nasal cavity is necessary to have substantial results. Hope this answer was helpful, but please do not hesitate to contact us again on the forum or by requesting a consultation if you have any more questions or to discuss it any further.

Thanks for using Petco Pet Education Center, formerly Petcoach! Yes, a CT scan would be the next diagnostic for something like this. This is very important as I am afraid this could either be a nasal cancer or possibly a severe nasal fungal infection. A CT scan helps to distinguish these conditions and a biopsy will help confirm it. Rhinoscopy is needed in some cases to better visualize the nasal cavity after the CT scan is done. Good luck and have a great day!
