A pet food dispenser has a container, a bottom lid and a receiving plate. The bottom lid is covered on a bottom opening of the container and has multiple through holes. The receiving plate is connected to the bottom lid. A gap is formed between the receiving plate and the bottom lid. The pet foods in the container drop out from the through holes of the bottom lid. Because the receiving plate collects dropped pet food, only some pet food is released for the pets to eat. The pets need to push the pet food dispenser to topple and roll so that more and more pet food is released. Therefore, the pet food dispenser efficiently leads the pets to move more by using food to attract the pets.
