- Absolutely no punishment is allowed: Scolding, hitting, or forcing a child's face to smell urine. It only made things worse. The dog will get stressed and will go urinate somewhere else instead.
- Take him/her to the veterinarian (most important): It's necessary to first check that the dog isn't suffering from any of these diseases: cystitis, kidney stones, or kidney disease. If the dog is sick, it must be treated for that disease.
- Clean properly: Use an "enzymatic cleaner" to eliminate odors at their source. Do not use ammonia. Because the smell is like urine, it will further stimulate you to urinate again.

- Take your dog to urinate in the designated spot at the same time every day (e.g., after waking up, after eating).
- Give the reward immediately. When he urinates in the right place (very important!).
- Restrict their area (use a fence) when we can't watch them.
