Ours is just coming to the end of her first one.

Thankfully Mrs Mul did some reading so I knew not to let her off the lead. She’s been an absolute sex pest(the dog, not Mrs Mul) - trying to dry hump everyone in the house with her big bulging vagina. I never knew a dog could look disgusted and furious until this fucker was staring my in the eye while trying to hump my elbow when I’m stuck on a work teams call.

Spoke to the vet beforehand and they said the guidance is to wait till the dog is at least 1yo before considering spaying.
