My dog's green nose discharge returns after antibiotics. What's wrong?

If the nasal discharge continues, especially only on one side, I would be concerned about a possible foreign body in his sinus cavity or even something like cancer. The next step if not already done would be lab test, potential he a CT scan of his skull or/and even a rhinoscopy where we put a camera up his nose to examine for anything. Your veterinarian can determine with you which of those steps would be best suited are even available in your area.

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.

Hello and welcome to Petco Pet Education Center, formerly Petcoach. If a runny nose is returning after a course of antibiotics has stopped there is concern for a foreign object stuck in the nose. Another course of antibiotics won't help. The best thing to do would be to scope or flush the nose to see if anything comes out, or to get a sample. Fungal disease is common in the US as well and is a consideration of cause. I would recommend a revisit with your vet. You can discuss allergies at that time as well, as a runny nose can be caused by allergies. Best of luck with Olive!

I think you need to get a second opinion from another vet, preferably one who has a rhinoscope and can actually look into your dog's upper respiratory passages. By examining the nasal passages with a rhinoscope one will be able to see whether there is a tumor present or more plant debris or foreign material that may need to be removed and so stop the constant infections and bleeding. Your vet may be able to refer you to a relevant clinic.

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.

Poor Sam! That is unusual and not expected. There are a few possibilities including infection, fungal disease, cancer, foreign body in the nostril or oral-nasal fistula. I recommend to call your veterinarian today. They may want to see Sam sooner. I hope he starts feeling better quickly!

Yes I would schedule a recheck if the discharge is still brown or yellow and hasn't started to resolve after a few days of antibiotics and other medications as it is possible there is something stuck in the nose causing irritation, or the infection requires more targeted medications. I would also make sure to keep Fray eating and drinking. You can also clear away any nasal discharge that is crusting around the nose to help keep it easier for her to breathe.
