Respond without adding alarm
If you discover an accident after it happened, avoid calling the dog over to inspect it. They cannot use a reprimand now to understand where you wanted them to go earlier. Move them calmly to another comfortable supervised area while you clean. Keep your voice and movements ordinary rather than turning the discovery into a household event.
If you notice toileting beginning, calmly offer access to the intended place when that is practical, without startling or grabbing the dog. Some accidents will simply need cleaning. The useful work is making the next opportunity easier, not trying to recover control of an event already underway.
Clean for the surface and the household
Use a suitable pet-accident cleaning product according to its label and the flooring instructions. Keep the dog away during application and until the area is safe to use again. Do not mix cleaners. Wash reusable cloths appropriately and store products securely rather than leaving the bottle on the floor while answering the door.
If a rug or absorbent layer has been affected, check beneath it as well. Persistent odour may require more thorough cleaning of the relevant material. Avoid covering the spot with a loose object that creates a new chewing or tripping hazard. Restore a usable, dry surface before allowing access again.
Review the moments before it happened
Ask a practical question: had the dog just woken, finished eating or become excited? Was someone meant to be supervising, or did responsibility become unclear? Note the circumstances briefly. One accident does not prove that previous teaching has disappeared or that the dog is acting deliberately.
Offer an appropriate outdoor opportunity and reward successful toileting there. Increase useful supervision or reduce unsupervised access temporarily if needed, while preserving comfortable rest and water access. A sudden change in an established pattern, apparent pain or other wellbeing concern belongs with a veterinarian. Cleaning and routine adjustments are helpful, but they should not be used to explain away a possible health problem.
