The NULL figures supplied by Nerd and Rob the Whiz are for human figures. Because the P4 dog has some differently named actors, these NULL figures will not work properly on it.

Attached above is the text of a  NULL figure I made (just this minute) for the P4 Dog. I hope it will solve your problem. Using NULL figures with a number of figures can be a bit complicated when you are not used to it, a small mistake can cause the process to breakdown, so follow the instructions from the "And then there was NONE." section of Rob's site exactly, and if it does not work the first time, try again, you may have made a slip.

It was necessary to add a ".TXT" extension to the NULL in order to post it here, remove the ".TXT" part of the extension when you save it to disk.

You may need to "prep" the dog's cr2 files, as explained on Rob's site, if they do not already use ":1".
