I made a quick post about the pause table changes last week, but that isn't the only thing that has changed in AKC Agility rules this month.
The A-Frame used to be 5'6" for all dogs, but has now been lowered a bit for the little dogs. So starting September 1st, all dogs jumping 4" or 8" get to have their A-Frame lowered to 5'0" - it might not seem like much, but when the dog is under 11" tall, even 6" makes a huge difference.
The tire has also undergone a height change, now being set 4" lower than before for all dogs. So now the 24" dogs will jump a 20" tire, 20" dogs - 16" tire, and so on. The two extreme heights get exceptions - 26" dogs will jump a 20" tire, and the 4" preferred class dogs get the tire placed on the ground (true height depending on the tire wall size, which is regulated to be between 3 and 8 inches thick).
The Dog Walk has also changed to exclude the up-contact, only requiring the dog to touch the contact zone (lower 42" from the end of the board) on the descent.
