Most dogs will never need an indoor toilet. Most dogs will also have four or five stretches in their life when one would have made everything easier.
Indoor toileting has a reputation as a lazy shortcut. In practice it is usually the opposite: a temporary answer to a situation where going outside is genuinely not an option.
1. The puppy who is not fully vaccinated yet
Your vet tells you to keep the puppy away from ground other dogs have used until the vaccination course is finished. Your puppy, meanwhile, needs to learn where to go — and the habits formed in those first weeks tend to stick.
An indoor spot lets toilet training start on day one without walking a half-protected puppy across the neighbourhood’s shared ground.
2. After surgery, and later in life
A dog recovering from an operation is often told not to do stairs for weeks. A dog with arthritis reaches the same point more gradually. Either way, the distance between the sofa and the street stops being trivial.
This is the case owners tend not to plan for, because it arrives suddenly — and then you are carrying a 20kg dog down four flights, six times a day.
3. Typhoon season
Hong Kong averages about six tropical cyclones a year that require a warning signal. In 2025 there were 14 — the most since records began in 1946. The season runs May to November, and July through September is the busy part. (Hong Kong Observatory)
Under a No. 8 signal you are not walking the dog. Nor during the rainstorms either side of it. The dog still needs to go.
4. Living upstairs
In a high-rise, a toilet break is a lift, a lobby and a walk — ten minutes, four or more times a day, in whatever the weather is doing. For an old dog, a sick owner, a newborn in the flat, or a 6am start, an indoor option is not indulgence. It is the difference between the dog waiting and the dog not waiting.
The options, honestly
Pee pads. Cheap and everywhere. They absorb liquid and then hold it flat against the surface, which is why the smell builds and why a dog that misses the edge has made a bigger mess than before. Disposable, so the cost never stops.
Artificial turf. Reusable and tidy-looking. Everything drains through to a tray you then have to rinse — and the drainage holes clog with hair sooner than the product page suggests.
Real grass. Dogs take to it fastest, since it is the surface they already associate with going. It is also alive, so it needs replacing every couple of weeks, indefinitely.
Mineral dog litter. The least discussed of the four, and the one that behaves most like what already works for cats: the granules absorb liquid on contact and clump, so waste is lifted out rather than left lying in a tray.
Why we made ours from the same mineral as the cat litter
Waggle uses the same natural attapulgite we build our cat litter from. The reasoning is the same too — the clay’s pore structure traps moisture and odour inside the granule instead of releasing it into a room you are also living in. No added fragrance, because covering the smell was never the point.
Paired with a tray that separates the dog from what it has just done, it stays dry underfoot, which matters when the whole arrangement is two metres from where you eat.
An indoor toilet is not a replacement for walks. It is what you fall back on when the walk is not possible — and those weeks arrive more often than most owners expect.
