No they haven't. Still waiting on our home visit. We haven't even seen the dogs in person, only though the pics on the rescue's facebook page
I would definitely want to see if it was a good match, personality wise. It's good to let them meet at a neutral location, then go inside and let them spend some time together.
A couple of years ago we were looking to adopt a young, small dog. We did the above, then spent quite a while in the room inside. My German Shepherd was so gentle she got rave reviews from the shelter staff. So all set, about to start the process of going home. I had new dog in my lap, and when my German Shepherd came over to me, new dog bit her twice in the face without provocation. New dog was what they call "lap aggressive". Shelter manager felt it wouldn't be fair to my older dog to have to live with that, and so did I, but it was kind of sad having to leave new dog there as she otherwise seemed totally sweet and we had fallen in love with her that afternoon. Shelter manager said to the dog, "This is the second family you've scared away now, yesterday you were mean to the other family's dog". Shelter manager also told me I had the nicest GSD she'd ever met - my dog didn't even bite back or get upset. (Ironically enough, since she could sometimes be reactive to other dogs. She seemed to like this dog a lot. Go figure.)
Later, we tried again at a different shelter's adoption day. Again, dogs got along well. We asked personnel if the dog was lap aggressive. Staff said no, dog wasn't. A few minutes later, a woman who'd overheard pulled my DH aside, said she was the dog's foster mom, and said that yes, the dog could be lap aggressive. DH thanked her for sharing, and we left, scratching our heads why they would not be forthcoming with such information. Idk.
Anyway, I think you have to see for yourself AND give it some time. If it turns out to be not a goood fit for whatever reason, they tell you to let them know, and generally they'd want the dog back so it could find a family that's a better fit. (Can't speak for all shelters, but this is what we were told by all that we dealt with.)
Good luck. The dogs are adorable. I doubt you'll have much problem, but you never know. Dogs can be funny sometimes in their personalities. They have an inner radar that we don't fully understand (IMO) that tells them they either like another dog, or they don't. When it's a don't, it can be difficult to deal with.
