what is wrong with my dog and how do I sort it out?

  my dog is 4 years old and she will not do any tricks or do Michal Jackson's moon walk!
not all dogs will do the tricks you want them to do. if you just keep practicing with her then maybe she will do one.
Try playing it some Metallica instead, it might not like Michael Jackson
Not all dogs do tricks. My dog doesn't. Just keep practising with her but don't worry about it
