Again don't know these dogs specifically (used to follow steel trap when they were just abs and neo/abs) but wouldn't herder blood sharpen them up and make them less tolerant of the typical shenanigans of children than a bull/mastiff? I mean you pay a price for all the positives herders bring to the table, and I think the main negative is that hair trigger, relative to bull/mastiff types. Ultimately making them better PP dogs better for working a decoy and etc, but not necessarily better family dogs.
