Denise Dalmatian is a puppy who has just come home from the animal shelter. She is full of energy and plans on exploring every inch of her new home. She loves her new owner and just has to investigate everything from the garbage can to the toilet paper roll. As she goes from room to room she makes a mess, not intentionally but that is what puppies do. The large Persian cat who lives in the same house is very upset at the new interloper. Will they become friends or will Dumpling the Persian make things worse? What will her owner say? Is she going to be sent back to the animal shelter?
