Before Sally I thought that pit bills were vicious, nasty dogs and were only owned by idiots who wanted a "tough" dog. Sally came into my life and totally changed my perspective on the breed as well as dogs in general. Not sure that I would get another (at least a young one) due to the dog aggression issues. Sally gets along beautifully with Jack but I know that could easily not be the case and our house really isn't set up for crate and rotate.
Before Jack, I'd never really disliked labs, but never found them all that exciting. When we were looking for a second dog, I wanted a dog friendly, large, athletic breed since Sally was energetic, dog selective, and didn't seem to have good "doggy language" skills. Now I love the breed! There are a few quirks Jack has that I could do without, but I think a lot of that has to do with training mistakes/laziness on my part.
I've never seen Jack as an OMGILOVEEVRYONEALLTHETIME dog. He is an attention ***** for sure, and enjoys pets from lots of people, but it's never really much beyond a greeting unless the person has spent some time with him. He definately has his favorite people-his top three are me, my friend Ann, and DH, in that order. I've been around goldens that I'm pretty sure would have been happy to go home with me after a couple of pets and never look back but I've never really gotten that feeling with Jack or most other labs.
