Counterintuitively, the fastest way to give your puppy freedom to roam the house is to restrict his freedom now to prevent accidents and establish good habits. Giving him full run of the house before he’s ready, will not set your puppy up for success. Besides being helpful tools for potty training, confinement areas are also crucial in teaching puppies what is (or isn’t) appropriate to chew on and how to enjoy time apart from you.
A short-term confinement area (crate) should be large enough for your puppy to stand up and turn around in, but no larger than 2x their size. Your puppy sleeps in the crate during the night, but otherwise should spend no more than 2 hours alone in their crate.
A long-term confinement area is an easily cleanable space bounded by an exercise pen or baby gate(s). Your puppy must be placed in the long-term confinement area when you cannot actively supervise them (no multitasking). Do not leave your puppy in their playpen for more than 4 hours.
What do I do if I catch my puppy pottying inside?
If you catch your puppy in the act, interrupt with a no-reward marker (“ah-ah”) said in a neutral tone, and take your puppy outside to her designated spot to finish. If she finishes pottying outside, follow through with your usual celebration routine (see above). If she doesn’t, simply put her in her crate for 5-10 minutes, then take her out and try again. Repeat this process, alternating between crate and potty spot, until she eliminates in the potty spot, then follow through with your celebration routine.
What if I didn’t see it while it was happening?
If your pup had an accident inside, but you didn’t actually see her do it, you’ve missed your teaching opportunity this time. Do not scold or punish her in any way — if you do, rather than teaching her not to potty inside, you’ll likely teach her that it’s scary to eliminate in your presence and next time she may decide to sneak off to a quiet corner of the house to eliminate in safety. So, if you find an accident on the floor after the fact, try your best to act neutral, clean up the mess without a word, and vow to be more vigilant next time!
When I take my puppy out, he sniffs and plays but doesn’t go potty. As soon as I take him back inside, he goes on the kitchen floor! Is he doing this to spite me?
Dogs don’t do things out of spite. It’s likely that he got distracted by novel sights, smells, and sounds while outside, and it wasn’t until he was back inside — away from the distractions — that he remembered that he really had to go. To help keep your puppy on task, have him on leash when you take him out to his potty spot. Once you’re there, stand still and only allow him to go as far as the leash reaches without you moving. If he doesn’t go after 2-3 minutes, simply put him in his crate for 5-10 minutes, then take him out and try again. Repeat, alternating between crate and potty spot, until he eliminates in the potty spot, then follow through with your usual celebration routine.
