Consistency is crucial. This may mean taking time off work to be there to take the pup outside every 20-30 minutes when they are awake. Crate training will also help the 'penny drop' as it teaches the pup to hold on until taken outside. Then, be sure to stay with the pup in the yard so you are there to reinforce how clever they are when they do go in the right place.
If your dog isn’t giving you an obvious signal that they need to go out (like whining at the door) I suggest teaching them to ring a bell when they need to go outside. Some of the other signs dogs give that they need to go out such as pacing around or circling can be easy to miss if they’re in another room, which is why a noise based signal such as ringing a bell can make things easier.
Work on only one part of a skill at a time Many of the skills we want our dogs to learn are complex. For instance, if you want to train a solid sit-stay, you’ll need to work on teaching your dog that she should stay in a sitting position until you release her (duration), she should stay while you move away from her (distance), and she should stay while distracting things are going on around her (distraction). You’ll probably both get frustrated if you try to teach her all of these things at the same time. Instead, start with just one part of the skill and, when your dog has mastered that, add another part. For example, you can work on duration first. When your dog can sit-stay for a few minutes in a quiet place with no distractions while you stand right next to her, start training her to stay while you move away from her. While you focus on that new part of the skill, go back to asking your dog to stay for just a few seconds again. When your dog can stay while you move around the room, slowly build up the duration of the stay again. Then you can add the next part-training in a more distracting environment. Again, when you make the skill harder by adding distraction, make the other parts-duration and distance-easier for a little while. If you work on all the parts of a complex skill separately before putting them together, you’ll set your dog up to succeed. Can I train my dog myself?
