I adopted a five-year-old GSD/Lab from a council round dog pound. I went in, picked a dog and went home with him.
They didn't ask me any questions as to whether I had had a dog before or what sort of home he would be moving into.
He was a lovely dog with me and my family and friends but would have been dangerous with kids or nervous people (most people to be truthful).
He died when he was 14 - we had nine lovely years together.
Vetting of people who adopt dogs is important.
