Not sure about it being an old wives tale but it certainly is true in my case so I tend to believe the experts- people who have had both as my experience has proved it. I have a black and a brown newf, my black is the most laid back dog that I have ever owned (a lot to do with the breed of course) she always does as she is told, she is a dog that loves to be praised and will do anything you ask of her. My brown newf on the other hand is the one that pushes the boundaries, she jumps up at people, tables, counters, she is cosnstantly on the go and is always looking for things to amuse herself - whether we like it or not :rolleyes: I wouldn't change either of them for the world because they are both fantastic but she is much harder work than my black newf. Sayng that though she is a walk in the park compared to my first ever dog who was a dobe. All you dobe owners out there will know exactly what I am saying.
