Oh No! It Appears Our Dog Schmingle Has Died.

Delete That Big Piece Of Candy (your dead dogs body)now you should see the core, turn that baby into a grave stone and call forth your dead dog, if you do not have this option then just wait for your dog to come over time.
oh yeah, and the more spooky your room is, the higher chance a dog will come back as a ghost, for example the default room would take around normal time for the dog to comeback, however. a room with spooky things like the pumpkin wallpaper and haunted floor will take less time.

Now That You Have A Ghost, Go Into The Dog Storage Menu And Click Export, Now Copy The Code, And Paste It Into Insert. Now You Have A Fresh New Dog! Please Remember You WILL Have To Rename It If You Do Not Want It To Have A Default Name.
