To solve problems that taking a walk with a dog gives neighborhood residents uncomfortable feeling, feces dropped on the ground must be brought back by picking them by hand and putting them in a bag, and it is not easy to pick up the feces by putting up an umbrella in a rainy day, and provide a device having an automatic cover for a movable toilet and making it possible to take an all-weather walk of a dog.

An owner can understand the instance of excreting feces in advance during taking a walk with a dog, so at that instance, the cover 4 of a toilet 3 attached to the top of a body 13 with wheels is opened by an open/shut lever 5 and the toilet is attached to the dog to directly discharge the feces into the toilet 3. After discharging the feces, the automatically shutting cover 4 is shut and the toilet is brought back to home and treated. A conventional umbrella can be set in a rainy day or a shiny day. In taking a rest. the toilet can be placed anywhere by a fixing stand 8. If the feces escape, they can be swept with cleaning scissors 11. The toilet 3 can be moved upward and downward by a height-adjusting screw 2.
