I had one, and I can say that the “calmer” part in the house was not accurate with her. She was an incredible upland dog with extreme high drive and would point quite often (no formal training for that). She was shorter and very stocky. However, she never really calmed down and acclimated to the house, even after rigorous training sessions. After knocking down my girls in the house for 3-4 years I finally kept her outside most of the time. I don’t know if they are all like that, but my experience doesn’t support some of the “qualities” breeders claim.
