It typically takes 3-4 weeks of consistent training for a dog to start automatically behaving in the way you want them to: During the initial training period, dogs are just learning the new behavior. Around the 3 week mark is when dogs start to understand that a certain action gets them a reward. At 4 weeks, the behavior has been reinforced enough times that it has solidified as a routine for the dog. Factors that can influence the time it takes for a dog to learn and form a habit include: Breed, age, and size of the dog Training frequency, expertise, and methods used The specific behavior being taught The household environment
