I am owned by a Great Dane. Monty is 39 at the shoulder, a true gentle giant. A good guard dog especially when the grandchildren are in residence. The only time he barks at people passing by the house, or sleeps in front of the door.

As intelligence goes...on the list more than 1/2 way down there...no matter...it may take him awhile to learn a command...but the love he gives makes him worth it. My Border was smart as a whip, but more interested in 'working' for you than kissing and cuddling.
