Hong Kong practical guide: How small flats + busy Hongkongers can see results in 7 days
Hong Kong homes are small and busy. To solve indoor peeing, the key is "observe → zone → schedule → reward → clean".
Day 1–2: Record patterns
Use your phone to note your dog's water intake, food intake, and urination times and locations. After one night you'll see whether it's "health-related urgency" or "behavioural marking".
Day 3–4: Zone management
Even a 300 sq ft flat is enough: place a playpen + pee pads in a corner of the living room, and lay plastic mats outside the playpen to prevent slipping. Before your dog learns, use a leash to limit their range and reduce chances of "ambushing" wall corners.
Day 5–6: Scheduled walks
For Hongkongers working 8am to 8pm, set "three time slots":
- 7:30am: 10 minutes before leaving, go downstairs or to the pet toilet downstairs
- 12:30pm: ask family/pet sitter to take the dog out once
- 7:30pm: immediately go to the designated spot after getting home Reward immediately after each successful toilet trip with a treat + verbal praise "Good!", rewarding within 3 seconds is most effective.
Day 7: Cleaning up
Hong Kong is humid; lingering urine odour will encourage your dog to mark again. Use an enzymatic cleaner (available at pet shops), spray thoroughly, wait 10 minutes, then wipe, and finally run a dehumidifier for 30 minutes to eliminate residual odour.
When to see a vet?
If you see blood in the urine for two consecutive days, your dog constantly licking their genital area, or sudden loss of toilet training despite being trained, book a vet immediately; don't wait for the weekend. A walk-in at a Hong Kong daytime clinic including basic urine test is about HKD 400–600; get results first before continuing training with peace of mind.
