The big news is the addition of the micro size category; general reshuffling of sizes and jump heights; and the possibility of "split" competitions if enough dogs compete in each size category (see New height divisions to take effect 1 July 2010). Some other changes include:

• Displacing the hoop (tyre) is now a fault.
  
  
• Elementary B (new handlers & dogs) now officially has no weaves but Elementary A (experienced handler but new dog) must include 6 weaves. Also, competitors winning out of Elementary B may now choose to progress to Elementary A.
  
  
• Judges may now set different standard course times for each height category in a split competition.
