I really want to get a Beagle, a GSD, or a Rottweiler. But I don't know if they're easy to train, or if they are good in Agility! Because I want to do Agility and Obedience with my new dog, if my parents let me! If you can, please post a picture or two of Beagles, GSD's or Rottweilers please! Thank you!!!
