House training
What should I do when I find an old accident I did not catch in the act?

Short answer
Simply clean it thoroughly with an enzymatic cleaner and move on, since scolding a dog for something that already happened, even a few minutes earlier, does not connect the correction to the behavior in a dog's mind. Dogs live very much in the moment, and a delayed reaction usually just teaches them to be nervous around you rather than to avoid accidents.
Why a delayed reaction does not work
By the time you discover an accident, the dog has already moved on mentally, and pointing at the mess or raising your voice at that point most often teaches them to associate your anger with your presence or the mess itself, not with the act of urinating indoors earlier. This can actually make house training harder, since a dog who becomes anxious about being caught may start hiding accidents in less visible spots instead.
What to do instead going forward
Clean the spot properly, then use it as information: note the time if you can estimate it, and tighten your supervision or schedule around that gap for the next few days. A pattern of accidents found rather than caught usually means supervision has been looser than the current stage of training calls for.
Key takeaways
- Scolding a dog for an accident found after the fact does not connect the correction to the behavior.
- A delayed reaction can teach a dog to hide accidents in less visible spots instead of preventing them.
- Use the discovery as information to tighten supervision rather than as a moment for punishment.
