Golden spaniels like to play rough, rough

I have to wonder if these Traits do not also show up in Humans of different hair color, races and ethnic backgrounds... Food for thought isn't it?, could Nature have bread some of us to be Aggressive to others of the same species?...

Could this be the cause of "Our Problems" these days?... More food for thought... The latest study, recently published in the journal Applied Animal Behaviour Science, shows that golden/red English cocker spaniels exhibit the most dominant and aggressive behaviour. Kinda like the German Version of the "Perfect Race" was Nature responsible for that also?... Black dogs in this breed are the second most aggressive, while particolour (white with patches of colour) are more mild-mannered. Earlier research suggests that hair colour is also linked to behaviour in labrador retrievers. Maybe Nature plays a bigger part in "Who we are than what we ever knew"... Think about who are the most "Peaceful People" in the world and who are the "Most Violent"... Makes me go Hmmmm?...
