There is no guarantee that an estrus cycle will change Sunny's vulva. My Naples has the same thing, and since she's a retired racer, I can tell you the approximate time frame when she was spayed. I know she was at least two years old, because her last race was not long after she turned 2. Which means, it is possible that she has had a season or two.

Now, I will also say this, though: Greyhounds are known to have their first seasons later than many breeds, often around 18 months to two years old. And, racers are usually given synthetic hormones to prevent cycles, to prevent "oops" litters, since intact males race with intact bitches (though they are turned out in separate runs).

But I would ask about doing a corrective surgery at the same time as the spay, to be honest. I would expect that would have been mentioned, if it were a possibility, though. And I would think there is a distinct possibility that, due to her age, she will continue to grow, making this surgery an inpossibility. Still, I would ask, just in case.

But I can tell you that the recurrent infections are no fun. We plan to get Naples corrected in spring, when she has her annual dental. I won't subject her to the anesthesia, unless things get worse in the meantime, so we will have it done all at the same time.

Best of luck!
