The 3-3-3 rule is a guideline for transitioning a rescue dog into their new home and helping them to settle in. It suggests that the first three days should be used for adjusting to their new surroundings, the next three weeks for training and bonding, and the first three months for continued socialization and training. The first three days are for adjusting to new surroundings and getting used to the owner, during which time the owner should limit exposure to new sights, sounds, and experiences, and provide a quiet and safe space for the dog to rest and recover. Start your daily routine right away but do not force interaction. The next three weeks focus on training and bonding with the rescue dog, starting with basic obedience commands and gradually increasing the difficulty of the exercises. The first three months involve continuing socialization and training, exposing the dog to a variety of experiences and environments, and taking them to the park, on car rides, and letting them interact with other dogs and people. The 3-3-3 rule provides a roadmap for the adoption process and helps ensure a smooth transition for both the dog and the owner. It also helps set realistic expectations and prevents common mistakes such as overloading the dog with too much too soon.
