I had a friend who worked in adoptions at the RSPCA, not quite pick a dog and take it home kinda of thing- i think you go on a list of preferances and i think the adoption officer will asses whether a certain breed/dog will work well in your family.
Im guessing this is similar to what you had to do?
We just went and had a look today. I just asked the lady if she thought they are a good breed for a family and she said about training them. I wanted to come home and do some research and make sure that it was something that we definately wanted. I told DH if he's still there when we make up our mind then it is ment to be. I had a look on the rspca website and saw that they sometimes go to the home and do checks. I know that having a dog is a long commitment so I want to make sure that i have done all the research and wanted to get some other opinions
