Yay for thinking about adopting a dog! I'm glad to hear that you're really thinking it through, and weighing the responsibility.

Having volunteered in a shelter and having answered the housebreaking question *a lot*, I'll say this: Most shelters (including mine) aren't set up to teach or reinforce housebreaking skills. There are simply too many animals and not enough staff and volunteers. So I recommend that you assume that your pup is not housebroken. Start from scratch and, if she was previously housebroken, it will come back to her pretty quickly. Kind of like riding a bike!

When we adopted Cody, it only took about 3 days before we were convinced that he was housebroken. No accidents in the house, but we watched him like a hawk any time that he was out of his kennel for those 3 days.

As for the car-sick thing, they got her to the garden, right? What did her handler say about her car behavior?

Goood luck with your decision! Post pics if she comes home with you
