I know the owner of DMRS is a certified trainer and puts a lot of time into evaluating her dogs, so she has a good idea of what each needs - and doesn't need, like whether they're good with cats, kids, other dogs, etc. No rescue wants to see a dog come back to them because it doesn't work out.
That said, sometimes it's harder evaluating the person... like when you tell them the dog needs house training, and they assure you they're fine with that... then return him two weeks later because he's peeing all over the house. Like....
