Uh-oh, this is quite concerning. This could be vaginitis, but probably is a uterine infection (pyometra, open). This is an emergency and she needs to be seen by a vet preferably today. Your vet will give Daisy a thorough exam, and then probably will want to do an x-ray to verify his diagnosis. Treatment is surgery to remove the uterus with all the pus contained. Antibiotics sometimes work, however that would only delay the surgery as she will have another uterine infection when she has her next heat. Please take her to your veterinarian ASAP.

    A scant amount of vaginal discharge is normal from time to time, but if you notice it several times in one day she should be evaluated by a veterinarian. My biggest concern would be an infection of her uterus called a pyometra. This is a life threatening infection, so if she is acting sick at all please have her seen immediately. Best of luck and thank you for using Pet Coach.

    This type of discharge can be very normal in a female dog that is coming out of her heat cycle. If the discharge becomes thick or colored, this could indicate an infection in the uterus. Also watch for signs of not eating, fever and vomiting. These symptoms could indicate an infection as well.
