Any breed can do agility, it helps if they are obedient when you start. You don't want to start training with a dog that has never been off the lead! You need to find a class, some have huge waiting lists, so you might have to wait a while to join. You can't compete until your dog is at least 18 months old, but the earlier you start training the better. Obviously a puppy would start with walking over jumps (on the ground), definitely no jumping. You can get them used to going through tunnels & also use V shaped training weaves. If you start competing it's great fun, a whole day out talking about dogs, you can't beat it
