Customer Question

My 9 month old female heat...has a tennis ball size mass coming out of her. I believe it's vaginal hyperplasia. Can anything be done or do we need to wait until it resolves?

I agree the most likely thing is vaginal hyperplasia based on your description. The best recommendation is to wait until it resolves, which will likely occur after she completes her heat.

In the meantime, it is important to keep it lubricated with sterile lube that can be applied numerous times per day, 6-8 times at least (no such thing as too much here). And placing a cone to prevent her from chewing or licking it. If she does damage the tissue or it becomes blue/purple, she may need surgery to repair it.

Another important thing is to make she she is still able to urinate. If she goes greater than 12 hours without urinating, she needs to see a vet and they can place her under anesthesia to manually reduce (push) it back in and place some sutures in her vulva.

The bad news is there is literature that says this will recur in about 80% of females. So if you were planning on having her spayed, do it as soon as she has completed her heat cycle to prevent this from occurring again.
