My problem is, I'm not sure what is meant by "vulva infection", it's awfully vague??? I'm going to assume, given that the vet didn't prescribe antibiotics that what she has is a condition called vulvar fold dermatitis it is a problem most often seen in older, or overweight dogs, and labs seem to be the most common breed with the problem. The skin folds surrounding the vulva trap moisture and because it is continuously warm and moist, it is the perfect breeding ground of bacteria... Often very smelly bacteria. The object of treatment is to keep the area clean and dry. Clean the area well, and often, with a mild gentle soap and water, taking care to spread the folds and clean all the way into the bottom of them, rinse well, and dry very, very thoroughly... I'd recommend a blow dryer on the cool setting to make sure you eliminate all moisture.... After that dust the whole area with cornstarch to help keep it dry. You can use an antibiotic cream such as neosporin to kill the bacteria at the onset, but once the area is no longer red and raw use the cornstarch... And keep using it, at least through the summer months. Be vigilant, particularly if she spends time outside... In the warm summer months this environment is a prime real-estate for flies to be laying eggs in.... And trust me, you don't ever want to know how disturbing that is, and how painful that is to the dog. For now try the wash/dry/cornstarch method, that should relieve her discomfort... If it becomes a chronic problem here is surgery for this type of dermatitis is very successful in alleviating the problem if it is done right.
You can also give he buffered aspirin (no substitutes) for the next few days to help dull pain associated with the treatment and inflammation... Once it starts clearing up discontinue the aspirin.
Aspirin: 5mg per lb. Every 10-12 hrs. (one 300mg tablet per 60-lb. Dog every 12 hrs.)
