My friends early spayed golden bitch was like this her whole life, each of my girls outgrew her in this behaviour by the time they were two, and she then became best play buddy with the next puppy we kept.
Sadly when she was 11 rough playing with a springer youngster she turned sharply and tore her cruciate and for her own sake I no longer allowed her to play with any youngsters I had, as she didn't have an off/moderation switch.
I have to say that her playmates were more than happy with her play style.
My current nearly 14 month old plays like this too, and I expect her to tone this down over the next year or so, but not much before 3.
