Tita most likely either has severe periodontal disease or uremic breathe due to an underlying kidney problem (less likely). Have her evealuated by your vet and highly consider getting her teeth cleaned. If she does have a foul odor then periodontal disease is very possible and she may even require some teeth extractions to get her back on track to having a healthy mouth. Oral hygiene affects the health of so many other organs, so it's important to get this treated quickly. Once she does get her teeth cleaned and obtains a healthy oral cavity, brushing her teeth daily can help her maintain this level of care and prevent severe dental disease in the future. Best of luck with your pet Tita!

    The smell from the mouth is likely to be a teeth/gum disease, although it could also be something more serious such as a tumor or a gastric disease. the sneezing with the discharge might not be related, this is likely to be a nasal infection. Tita needs to be seen by a vet in order to solve these problems.
