Hello, my name is Dr. Shines and I agree this is concerning. I suspect Pacha has an infection either in her vaginal canal or in her bladder. Some vaginal discharge is normal but the odor and increase in leakage is not. I recommend to make an appointment this week to have Pacha examined. The veterinarian will likely test a urine sample to determine if that the source of infection. Antibiotic selection will depend on the source of the infection. If it is vaginitis, she may get an antibiotic and a probiotic. One other thought, you may also ask the veterinarian to check her anal glands. Anal gland excretions are a VERY common cause of bad smell from the back end of pet. Sometimes the glands are infected but sometimes they are just full and benefit from being expressed. I hope this helps to provide some guidance and that things get figured out quickly.
