FIRST get proof of hips/elbow certification. This is absolute minimum!!! Also remember almost all dogs are confident and stable on home territory, ask t see the parents elsewhere. This is one of the reason people work/train their dogs. All dogs listen at home with no outside pressure. Take the dog out and see if passing animals are safe, how it is with kids, bikes, loud unexpected noises. Nothing worse than rearing and loving a dog who is afraid of thunder, kids, dogs, etc...Good luck, there are great dogs in all types, but you must do your research. Remember this will be family for 10+ years, adn you must live with it, so put in the research!!!
