With my next female I would spay her (uterus and ovaries) after the second heat so she can develop first. Spaying because first: WD is in tact, hopefully still by that time and second: I don't want to deal with heat cycles every 6 months for another 10 years, interfering with her exercise, hikes, sport events and the local coyotes. Heard from a local dog owner that she was followed in the forest by a coyote when she walked her female that was in heat.
I thought about the alternative of leaving the ovaries but the only thing that changes is that she is not bleeding (no uterus).
