It’s an instinct for your dog to want to investigate things you put near his muzzle, so he is likely to touch the bell lightly with his nose. Be ready for that moment and click and treat. If he is apprehensive, put the treat very near the ribbon of bells so that he almost HAS to touch them in order to get at his treat.  When he touches, click and treat!
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.
On a side note, a puppy’s mother can actually do a lot of the potty training for your dog. I know of several reputable breeders who tell me that the mother dog trains their pups not to eliminate in their nests. From the moment a puppy is born its mother is teaching it that the NEST is the place where it eats & sleeps. One of the first rules Mama Dog starts to teach her pups is NO peeing or pooping in the family nest – That’s Disgusting! And she makes them follow her outside.
A Hungarian dog training group called Népszigeti Kutyaiskola use a variation of model-rival training which they describe as the Mirror Method. The mirror method philosophy is that dogs instinctively learn by following the example of others in their social sphere. Core to the program is including the dog in all aspects of the owner's life and positive reinforcement of copying behaviors. Mirror method dog training relies on using a dog's natural instincts and inclinations rather than working against them.[71]
This method is the most effective and flexible. Your pup needs to develop his natural "den instinct" and learn where to eliminate - and where not to. To potty train our puppy we must condition a desire in the pup to avoid soiling the "den" - your house. Confinement and your due diligence in providing access outside the "den" to potty and poop will develop this instinct and eventual desire. When and how to use confinement is described in detail below.
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.
