I have found over the years that to train a dog, the best thing to do is keep things simple for you and the dog. There are different methods used for toilet training your dog but the method I have found the easiest is using paper as I will outline below.
Puppies normally prefer to soil on paper than on the floor and more then likely they would have been born on paper and also have spent the first six weeks of their life on paper because it is a lot easier to replace when dirty.
When you have brought the puppy home and you are setting up where the puppy is going to have its bed keep the paper outside of the bed and have a blanket or bedding for dogs in the basket, this will stop the puppy from soiling its bed. First thing everyday when you get up, carry the puppy to where the paper is and that will encourage the pup to go to the toilet. If you walk the puppy to the paper it could have an accident along the way. At the end of each day change the paper and move the paper closer to the door, as each day passes and the pup gets used to soiling the paper. Slowly move the paper outside the back door, if the paper is soiled do not change it as to remind the puppy when it goes outside to continue to soil on the paper. If the paper is kept in the same location all the time the pup should in time always soil in the same spot so it will become much easier for the owner to keep the back garden clean, something which is very important if there are young children in the house.
