Dog training is the application of behavior analysis which uses the environmental events of antecedents (trigger for a behavior) and consequences to modify the dog behavior, either for it to assist in specific activities or undertake particular tasks, or for it to participate effectively in contemporary domestic life. While training dogs for specific roles dates back to Roman times at least, the training of dogs to be compatible household pets developed with suburbanization in the 1950s.

A dog learns from interactions it has with its environment. This can be through classical conditioning, where it forms an association between two stimuli; non-associative learning, where its behavior is modified through habituation or sensitisation; and operant conditioning, where it forms an association between an antecedent and its consequence.

There are a variety of established methods of animal training, each with its adherents and critics. Some of the better known dog training procedures include the Koehler method, clicker training, motivational training, balanced training, electronic training, model-rival training, dominance-based training, and relationship-based training. The common characteristics of successful methods are knowing the animal's attributes and personality, accurate timing and consistency. The use of punishment is controversial with both the humaneness and effectiveness questioned by many behaviorists. Furthermore, numerous scientific studies have found that reward-based training is more effective and less harmful to the dog-owner relationship than punishment-based methods.
