Pre-Routine is the part of a disc dog freestyle competitive performance before the first disc is thrown to the dog.
Usually about 10-25 seconds or so, the Pre-Routine allows dog and handler to get warmed up and comfortable on the field and allows you to showcase or highlight the relationship and connection with your dog.
In contests, traditionally, time starts when the first disc is released with the intent for the dog to catch it.
Pre-Routine also functions as an athletic, on-field warmup.
