Attending class once per week is ideal! This way, both you and your dog have time to absorb the new information and put it into practice before you have to take on something new.
We would still suggest not taking more than 1 or 2 classes per week and definitely not two classes on the same day. Your pup will be too tired or full by the second class to gain as much benefit.
Of course, as with all our programs, please complete all your classes before your credits expire (3 months from purchase)!
