I have a 16-1/2 year old Pit Chow mix named Red. He has been extremely ill for the last 3 months, sneezing yellow discharge all day long. He has been on oral & inject-able antibiotics which did not alleviate the symptoms. My vet said the next step is a specialist to see if he has a fungus infection in his nose which would cost thousands of dollars. He also said my dog was too old to go under an anesthetic to have the test run. I was ready to give up hope when I investigated essential oils on the net. What did I have to lose? I put Geranium Essential Oil in a vaporizer & on his nose. Its only been 2 days & the symptoms are almost gone. I do feel bad because I know the essential oil is so strong for his nose but he can breathe easily for the 1st time in 3 months. I felt I needed to share this remedy which has been a miracle for my wonderful old Red dog.
