Why are you all so down on dogs being "protective"?
My Border Collie, Ewan, (a pet, not a work dog,)would protect me against all comers.
When my husband gives me a kiss and a hug, Ewan goes mad, barking furiously. It`s a good game.
But I feel secure when out walking because I am sure that if I was attacked for real he would wade in and mean it!!
By the way, I personally wouldn`t choose a male dog again. I always had bitches before, and they are far more biddable and quiet. Also males make the yard stink because they pee everywhere!!!
