There are numerous things this could be. Please call your vet and ask to be seen. I always start with an exam and a good history and then talk about potential possible causes and discuss rhe myriad of treatment options In some cases we chose an antibiotic. In others we talk about dental disease and it’s affect on the nose and discharge. We also talk about cancer and nasal flushing for foreign bodies. Even allergies are a possibility.
Please see a vet for which might be most likely in your dogs case.
