Once your puppy is reliably going only on the papers you've left, then you can slowly and gradually move his papers to a location of your choice. Move the papers a little bit each day. If puppy misses the paper, then you're moving too fast. Go back a few steps and start over. Don't be discouraged if your puppy seems to be making remarkable progress and then suddenly you have to return to papering the entire area. This is normal. There will always be minor set-backs. If you stick with this procedure, your puppy will be paper trained.
Before enrolling with a particular club contact them and ask if you can go to watch a class without your dog. This will help you decide if this is the right environment for you and your dog. Some clubs have waiting lists and you will need to book ahead, some accept people on a roll on roll off basis. Prices will vary from a joining fee and then weekly payments to a one off fee for a certain length of training.
