Establishing good habits early on in house training your puppy is critical.
If you allow your puppy to eliminate every where and any where he wants in your home, you will end up with an adult dog that will always have a tendency to want to eliminate in your home. You will have to live with it forever, or go through some time-consuming, tedious retraining later on. A dog is either house trained or not.
There is no such thing as weekly 'accidents.' A truly house trained dog will NEVER eliminate in your house unless forced to do so or because of illness or excessively long confinement.
Don't expect your puppy to be reliably house trained until it is at least 6 months old. *** Remember to take dog out same door,
same spot and praise and reward with special treat
