Potty training a westie puppy follows the same principles as any breed, but the westie temperament adds a layer of complexity. These are independent thinkers who may understand perfectly what you want and still decide the rug is a more convenient option than the cold grass outside. Consistency and patience are the only things that work.
The Schedule
Young puppies can’t hold it for long. The general rule: a puppy can hold their bladder for roughly one hour per month of age. A 3-month-old can hold it about 3 hours. An 8-week-old needs to go out roughly every 1-2 hours when awake.
Take your puppy outside at these times without exception: immediately after waking up, after every meal, after play sessions, and right before bed. In between, go out every 1-2 hours during the first weeks, extending the interval as they grow.
Go to the same spot every time. Westies are routine-oriented despite their independent streak. Using the same spot builds a strong location association: this spot means bathroom.
Reward Immediately
The moment your puppy goes outside, reward. Not when you get back inside. Not after they finish sniffing around. The instant they squat or lift a leg in the right spot, treat and praise. The timing is everything – even a 10-second delay weakens the connection between the behavior and the reward.
Use high-value treats for this. Regular kibble won’t create the strong positive association you need. Small, smelly, delicious treats that your puppy only gets for potty success.
Handling Accidents
Accidents will happen. When they do: clean it up with an enzymatic cleaner (not just soap) that eliminates the scent. Dogs return to spots that smell like previous bathroom locations, so removing the scent is critical.
If you catch your puppy in the act, interrupt with a sharp “ah-ah” and immediately take them outside to the correct spot. If they finish outside, reward. If you find an accident after the fact, don’t scold. Your puppy has no idea what you’re upset about. Punishment after the fact only teaches them to be anxious around you – it doesn’t teach them to go outside.
The Westie Stubbornness Factor
Here’s where westies differ from eager-to-please breeds. A golden retriever puppy who gets rewarded for going outside quickly develops a desire to please you by going outside. A westie puppy who gets rewarded for going outside thinks “I get treats outside, good to know” – and may still choose the living room rug on a rainy day because it’s warmer and closer.
This isn’t a character flaw. It’s the terrier brain doing cost-benefit analysis. Your job is to make the outdoor option consistently better: higher-value rewards, verbal excitement when they go outside, and absolutely zero punishment for indoor accidents (which only teaches them to hide it, not stop it).
On cold or rainy days, some westie puppies will refuse to go outside. Stand there calmly, wait, and praise heavily when they finally go. If they won’t go after 5-10 minutes, come back inside, supervise closely for 15 minutes, and go back out. Eventually they’ll have to go, and you’ll be there to reward it.
Crate Training as a Potty Training Tool
Dogs naturally avoid soiling their sleeping area. A properly sized crate (big enough to stand, turn around, and lie down, but not much bigger) leverages this instinct. When you can’t supervise directly, crate your puppy. When you take them out of the crate, go immediately outside to the potty spot.
The crate isn’t a punishment tool. It’s a management tool that prevents unsupervised accidents and builds bladder control. Never leave a young puppy crated longer than they can physically hold it.
Timeline Expectations
Most westie puppies are reasonably reliable by 4-6 months with consistent training. “Reasonably reliable” means occasional accidents are still normal, especially during excitement, when routines change, or in new environments. Full reliability usually comes between 6-12 months.
If a previously potty-trained westie starts having accidents, that’s a vet visit – it could indicate a urinary tract infection, digestive issue, or in older dogs, cognitive changes.
