It's a great place to start. Once you start seeing results, and then all of a sudden he doesn't seem to be changing anymore you'll kow it's time to increase the work. Don't beat yourself up over a set schedule, just get that dog working as many small intervals a day as you can both handle and stick to it! A break is ok on occasion..
