Bonus 1 — The 14-Day Plan to Quiet the Barking
This plan turns the 3 R's method into a small daily task. You don't need any special materials. What matters is doing it every day, even if it's short. If you miss a day, pick up the next day without trying to make up what you missed.
Bonus 1 of the guide "Your Dog in an Apartment": 6 pages in PDF. You can buy it on its own, or get it included in the bundle with the guide and both bonuses.
