Historically we always kept a b!tch, until my first male around 17 years ago. He was the most loyal loving dog I have ever had. We have two girls now and a young male (un neutered), and I have to say, although the girls are lovable, our little man is just a wonderful cuddly teddy bear, and all he wants is love and cuddles.
Have to say that I have met quite a few not so nice natured labradors of late, especially the chocolate variety, who seem to be rather boistrous, stubborn and can become aggressive if not corrected while young.
