Consult the Progress checkpoint | Beginner, does your dog meet all the criteria for the intermediate level exercises?
Is your dog able to, consistently, complete your intended goal of Intermediate level exercises in one session?
Keep in mind that we do not necessarily transfer the intended goals from beginner level to intermediate level. The introduction of multiple reps and/or poles constitute an increase in difficulty. As we increase difficulty in one aspect (i.e., the number of reps/poles), we decrease the difficulty in other aspects (i.e., the number of sets/reps)
For example, your dog was able to complete 2 sets of 10 reps (a total of 20 reps) in Ex 2.3 (Beginner level). Your goal for Ex 2.5 (Advanced level) may be to complete 2 sets of 6 reps (a total of 12 reps).
