I agree Jacks need a lot of attention, as do all dogs, and they are like babies....picky picky. But it is a smart, loveable, cuddly, intelligent dog to have. With proper training it would be a wonderful addition to your home, and it looks great too, the All Anerican Dog. I have a Jack & Chihuahua mix, and she is too sweet, she's 5 months old and can sit, get down, lay down, roll over, and shake, and she loves to lay on your lap and be right next to you. She has no 'meanness' whatsoever, and Chihuahua's are known to be fisty too.
