The information in the included leaflet is insufficient and misleading, but the pool itself is very good. For a small child, or in my case a dog, it’s sufficient. It includes one patch; you can inflate it by mouth, but a pump is recommended. Fits perfectly on a balcony so even the dog can cool off in the heat.
Our puppy doesn’t use it for toileting at all, probably because the material isn’t pleasant. Instead, it prefers to relieve itself on a baby changing mat, which is likely softer and nicer.
