Ideally, toilet training should begin with the breeder, and needs to be continued when you get home. Choose a waterproof floor area for your puppy to sleep and cover the floor with newspaper. Carry puppy outside and stay with him until he has performed, using a word which he will associate with toileting for the rest of his life. Choose a word which will not be associated with anything else eg “toilet”, “perform”, “be clean” etc. Praise him like crazy when he performs outside and ignore any mistakes inside, just quietly clean up and say nothing. Do this when puppy wakes up, after he has fed, after playtime and before bed, in other words around 16 times a day to start with. Once you have established a pattern, you have cracked it!
Gradually, when the puppy is more reliable at going towards the door, you can put newspaper just in that area. When he moves towards the door, open it and take him out. When you learn to “read” your puppy’s body language and you’ll be nearly there! The more effort you put into toilet training at a young age, the quicker he will learn.
Never reprimand your puppy for a “mistake” in the house.
