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.
Put 2 dogs (preferbally same specie) in the wardrobe room and get out loads of love heart pillows & 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 spray them. Note: Love biscuits can help aswell. Leave or play with them for about 7 mins and soon they will make love and have a puppy, aarrr how sweet. Have fun!
