Dogs relationship after first heat?

Will my pomskies continue to have a friendlier relationship after my girl’s first heat?

So I have two small pomskies, a 2 y.o. male (Sir) and a 7 m.o. female (Dame). The female is in the middle of her first heat, shortly after she will be spayed. Our male will remain intact for now, since his breeder wants him to stud.

Before the heat cycle, the dogs liked walking, running and playing together, but they didn’t cuddle together, and our male was slightly food agressive with her. Dame looked up to Sir, but he didn’t reciprocate the affection. It seemed he thought she needed to learn her place.

Now that our Dame is in heat, Sir loves her. They are currently sexually frustrated in their diaper and belly band. When he tries to get humpy, I push him off. But now Sir is SO SWEET with Dame. He licks her, whines when she goes out of sight, he shares his chewies and bones with her. They fall asleep cuddling.

I know Sir won’t be obsessed with Dame when she’s not in heat anymore. But I wonder if this experience will bring them closer together. Hopefully they will continue to cuddle?

Does anyone have experience with this?
