I always had male labs and still feel they are hard to beat. A Lab just has a great personality, loyal, loving,smart, and mine always were good watch dogs. Protective of children and always warned me if trespassers were around. My last one would have torn anybody apart if they laid a hand on my daughter. We now have a Scottish Terrier house dog and he is very protective of our home. While he would/could never defend or attack, he does a great job of letting us know if anyone is around. He can hear , from inside our house, if anyone is even 50 yds from from our house. Incredible hearing. He will go to the side of the house that the "walker" is on and start growling. He has done it many times. IN a SHTF scenerio, he is definatly part of the team.
