Well you just opened Pandora's box! You're probably going to hear about just about every breed under the sun. I won't tell you my favorite. But I will tell you about one on your list.
My brother has a German Shorthair Pointer, his second one. Not the dog for me, but a good dog nonetheless.
This is what I can tell you about my experience with this dog:
He is absolutely tireless, you will have trouble keeping up with him!
No shedding. If he does, the hair is ultra fine and ultra small. You can barely see it at all!
Great watch dog! If I get up at night, quiet as a mouse, he barks!
Now my brother's always wants to outside being active. He's not a couch potato except at night and morning nap time.
Hope this helps,
Best
He never leaves my brother's side. Even in the bathroom! If my brother is at my house and closes the bathroom door on him, the dog will try to break the door down.
