The poodle, ref. 11575, is not available in LDraw library. But it is available in LDD, and thanks to a conversion tool is available from http://www.digital-bricks.de/en/file.php?part=11575 . This raw converted part is not completely up to LDraw standards and needs a bit of polishing, but it's a very good base!
The sign is in LDraw library, 13459.dat (adapted from LDD data too by yours truely!)
