Do you guys do a down/sit or just a stand? Pros and cons? Is USDAA the only one you need a down for nowadays? I feel so far behind on the new rules. My trainer is recommending a down for us because she says that dogs tend to hold the downs and sits better than just standing. She also says that I need to be able to build some distance with Mia while she's on the table because she's so fast, it'll give me some time to get out ahead of her.
