The reason why I don't want the "love of fight" to be a main source of pp instinct is because a dog who loves to fight can very easily find himself in a fight for the wrong reasons. Sure, you can say "That's why you train the dog when/why/how to fight." But the love of fight is still there. And in a situation where you don't have 100% supervision 100% of the time, Ive seen bad things happen, simply because the dog is looking for a fight. Not my ideal for an in home family protector. In addition, its very important to know why the dog loves to fight and to what level he is willing to take the fight.
Since any dog I use is simply a family pet/protector, I don't want a dog walking around free range who loves to fight. Now perhaps I misunderstand fight drive a bit. Im no expert.
Lets put it in human terms. Most men who "LOVE to fight" often find themselves in sticky situations. I used to LOVE to fight. It brought me nothing but trouble. MMA fighters who LOVE to fight often don't do nearly as well as others. Marines love to fight more than the rest of the military. And more of them die, more of them divorce, more of them commit suicide than any other branch (per capita). I raise/breed bulldogs. You cannot build their PP skills on a fight drive base. They are constantly looking for a reason to fight and are constantly looking for the bad guy. Not my type of dog mentality. Maybe its different in mastiff types. I wouldn't know.
