At first, it was an inconvenience; stepping on a damp patch first thing in the morning. But he keeps going back to the same spot and peeing, despite your best efforts to clean the area.
The whole situation is very frustrating. Not least because you work hard at getting rid of the smell, but a friend told you that the cleaning fluid contains bleach and is heightening the urine smell to the dog.
If you can't punish the dog and shouldn't use household cleaners, then exactly how do you end this anti-social habit?
Therefore, it's crucial to develop a strategy that involves retraining the dog as to where the correct place to go to the toilet is, alongside a rigorous deodorization of the area. Even then, this requires considerable dedication and patience, if you are to win out in the end.
Tempting as it is, never punish the dog. This is liable to make matters worse, rather than better, and damage your relationship to boot.
