Oh no, poor Bonnie! If the antibiotics are not helping with her sneezing bloody snot, then I would be concerned that her symptoms are caused by something more serious such as a fungal infection or even a tumor. I would take Bonnie back into a vet tomorrow for further testing such as blood tests, urinalysis, a culture of her nasal passages, chest x-rays, and an x-ray of her head. These tests will help the vet see if there is another cause of her symptoms, and then can discuss treatment options with you.
