I made this sign so my wife and I will know if there other one has already fed our dog.

Similar to the "clean/ dirty" dishwasher signs. If you just gave your dog breakfast you slide the slide to cover the word "breakfast" so it will read "I want dinner" and vice versa. Fairly self explanatory. Probably would work for kids also if you don't give them lunch and don't feel like just asking them.

Just place the slide on the "breakfast dinner" section and then glue the "I Want" section on top.

My wife painted it beforehand so it didn't look to boring but I'm not going to tell you how to live your life.
