The first step in house training your puppy or dog is to establish a routine. Much like babies, dogs do best on a regular schedule.
Take your dog out regularly to establish a place outside where they are to go the bathroom. When teaching puppies, make sure you take them out immediately after sleeping, eating, or playing. Those are the times a puppy is most likely to have an accident.
When you're unable to watch your dog/puppy, they should be confined to a crate. Crate training your dog/puppy is the best thing you can do to cut down on accidents in the house, as well as destructive behaviors. We have a section on our website with a "How to" video on crate training. Check it out!
