Has anyone tried herbal remedies in treating a dog who has a stuffed up nose and is sneezes at least 5 times every half hour. The sneeze is very snotty. We have been to the vet and had various medications, an xray which showed a lump on his nose. He then had a biopsy which proved to be just a thick tissue on his nose. The vet has no idea what to do next and wants to send him off to the university for them to do more tests. I have lost faith with the vets and would like to try homeopathy or herbal remedies. Any ideas?
