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.
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.
