Dog training is a lifestyle, training should never stop. I compare dog training to dieting and working out. Lets say someone who normally doesn’t eat healthy or workout decides they want to lose 20lbs, so they workout for 2 months and diet, lose the weight and abruptly stop working out and eating healthy. What do you think will happen? If a person is naturally lazy and doesn’t have the determination to stay fit instinctive drift will kick in and they go back to their usual routine. Instinctive drift means that your natural instincts are always working against your learned behaviors. When this happens and they stop eating healthy and working out the weight starts coming back on. Similarly in training a dog, the bad behaviors creep back in once you stop training.
