You want to keep your sessions short. 5 to 15 minutes max. The shorter the better. You can do multiple sessions each day, just keep them short. Make them fun and always end on a positive note.
It's okay to use mulitple commands. You want to be sure he's understanding the commands you start with as you add new ones
There are other ways to teach during these times as well. When you are playing and the dog exhibits behaviors you want, use the command word you want to assign to that behavior. The dog's running toward you?--"good come!"
