Oh yes Maddex already has that drive, but he gets 2 of those hour walks a day that leave him pretty zonked and HE LOVES to do tricks, never seen a dog that loves to hear the treat bag coming out so much they start sitting, and laying down before I even give the command. He's picked up sit, down, paw, and roll over so quickly and has them down pat to the point I just have to say the command! Pretty stoked about that.
Samson is in a world of his own at the moment, really independent of everyone including Maddex but I'm sure that personality will change like it did with Maddex as he gets older.
[Fixed: It read like we took him for two hour walks a day, rather then two separate hour walks a day!]
