I meant Rally Excellent A by the way - not Advanced! I enter the "A" classes if I can - I just feel that my dog and I need all the help we can get! I had to enter Skippy in Rally Novice B because I had titled a dog, but after that, I can enter him in "A" classes for Rally if I want to (I don't see him ever getting an obedience title)
Don't feel bad - people are always asking what they should enter in, and I have to read the rules everytime, and even then get confused. You can enter A if you want to, or B. Anyone can always enter the "B" classes. In rally especially, it shouldn't really be judged any differently, but I think that sometimes the judges might be a tad more forgiving of the "A" people. I know that it is harder for Emilu and I to place now that we are in B classes for her RAE title (she has both Advanced, Excellent, and her CD -so she is definietly in B classes for Rally)
