Why is my spayed lab still having yellow discharge after antibiotics?

I am assuming she is on an antibiotic. if not, then your vet should start her on an antibiotic. If she is on an antibiotic then you should call your vet as he/she may want to change antibiotics. After 4 days, I would expect any discharge to be decreasing.

Stump pyometra is a common sequela to retained ovarian tissue in the female dog. This can happen when the surgery was performed, As the ovary continues to produce progesterone and estrogen in cyclical fashion, any remaining endometrium is stimulated and fluid accumulation within the uterine stump occurs, increasing the chance for infection during diestrus. Ideally an ultrasound is needed to make sure there is no remnant of the ovaries left. If antibiotics are not effective, a bacterial swab should be ideally performed to identify specific type of bacteria and most appropriate antibiotic.

It would be best to have your vet recheck this. Pyo can be a concern at any age. Even if the dog hasn't had a heat before. They can also have very severe UTIs which can be resistant to certain types of antibiotics. It would be best to do a culture of the discharge to make sure the medication you are giving is working and that you know exactly what type of infection you are dealing with. Good luck and I hope your girl feels better soon!

Symptoms of a stump pyometra include discharge, vomiting, anorexia, lethargy, increased thirst, and increased urination. Your vet can do a blood test and urinalysis to see if Chutki has a UTI as opposed to a stump pyometra.

No, that is not normal. She should be put on broad spectrum antibiotics. There may be an infection in the uterine tissue that is remaining in the abdomen (stump pyometra). A second surgery may be needed to remove the infective tissue. The bloodwork shows a high white blood cell count indicating infection. Some of her liver enzymes are mildly elevated but I don't think they are significant at this time. She needs to be evaluated for a stump pyometra.

Vaginal discharge can be caused by a number of things. Both the urethra and vaginal openings exit the vaginal/vulvar area so discharge could indicate a problem with the urinary tract or with the reproductive tract. With any strange discharge, it is a good idea to schedule a veterinary appointment to check it out. If the discharge becomes cloudy, green or yellow in color, it is best to seek veterinary care as soon as possible as that may indicate something more serious such as a uterine infection (in unspayed females, but can occur if part of the uterine stump is left during a spay).

Yes, it is definitely worth a trip to the vet. Even if she did not previously have an infection, Shiloh may be dealing with one now. Infections of the uterus (called pyometra) can sometimes present this way, and they can be deadly if not treated. She may also have a vaginitis or urinary tract infection that needs treatment. Good luck, and I hope Shiloh feels better soon!
