House training succeeds or fails on timing: a puppy's bladder has a limited hourly capacity that grows with age, and every meal adds fluid load that needs to come out again soon after. This simulator runs a virtual household clock over a 3D floor plan — bedroom, kitchen, living room and yard — while a puppy eats, rests, wanders and needs to go, reacting to whatever feeding and walk schedule you set.
Most trainers agree accidents are a scheduling problem, not a stubbornness problem — a puppy taken out before its bladder reaches capacity almost never has an indoor accident, which is exactly the balance this simulator lets you test.
A virtual puppy lives out a day inside a 3D floor plan — crate, kitchen, living room and yard — while a schedule clock and a bladder-capacity gauge react live to the feeding and walk intervals you set.
Bladder capacity scales with age (roughly an hour per month up to adulthood) and every meal adds fluid load. If the gap between walks outlasts the gauge, the puppy has an accident wherever it happens to be standing.
Set the puppy's age, feeding interval and walk interval, then speed up the clock to watch a full day play out. Use "Take out now" to intervene early, and see how successes, accidents and your streak respond.
Most house-training "failures" are really scheduling mismatches — a puppy walked before its bladder gauge fills almost never has an indoor accident, exactly the balance this simulator lets you test.
