Yes— a foldable indoor dog cage with a toilet tray can be used for puppy potty training, but it works best as a managed “potty station,” not a substitute for a full house-training routine. The tray gives your puppy a consistent, easy-to-clean place to eliminate when you can’t get outside fast enough (overnight, apartments, bad weather, or during recovery after vaccinations). The foldable design also makes it practical to move between rooms or store when not needed.
A toilet tray inside or attached to a cage can reduce accidents by guiding your puppy to one designated spot. This is especially helpful for very young puppies with limited bladder control, or for owners who need an indoor option during work hours. It can also support crate training by creating a clear boundary: resting area on one side, potty area on the other—provided the enclosure is sized appropriately.
To avoid teaching “it’s always okay to go indoors,” keep the tray routine structured. Take your puppy to the tray on a schedule (after waking, eating, playing) and reward immediately after they use it. If your long-term goal is outdoor pottying, gradually shift from tray use to outdoor trips by increasing outside opportunities and limiting tray access to specific times. Avoid leaving unlimited access all day if your puppy is already capable of holding it for short periods.
If the cage is too large, some puppies will sleep on one end and potty on the other, which can weaken housetraining habits. Another issue is infrequent cleaning—odor residue can encourage repeat soiling. Use an enzymatic cleaner, replace pads or rinse the tray promptly, and keep the resting area dry and comfortable so your puppy naturally prefers to stay clean.

Start by taking your puppy outside first at every scheduled potty time, then allow tray access only if they don’t go within a few minutes. Over time, reduce tray availability to specific times (like overnight) and reward outdoor successes heavily so outside becomes the default.
