Place two dogs of opposite gender (preferably the same breed) in the wardrobe room. Take out plenty of love heart pillows and love spray and scatter them across the floor, then put a melody player on the chair and play a sweet song. Let the dogs play in the hearts, and the spray will automatically activate on them. Note: Love biscuits can also help. Leave or play with them for about seven minutes, and they will soon have a puppy.
Note: This procedure requires editing a game file; creating a backup copy of the file before proceeding. Look for the "Daphne" folder in the game directory. It contains all the art files for Daphne, which can be modified and saved to your liking. This can also be done with all other art files.
Don't buy the book of secret tricks on every dog profile. Only purchase them on one profile, then just remember the tricks and use them on your other dogs.
