Researchers have described several reasons why the dominance model is a poor choice for dog training.[75] First, a relationship based on dominance is established to gain priority access to scarce resources, not to impose particular behaviors on the less dominant animal,[76] so the dominance model is irrelevant for most of the behaviors that people want from their dogs, such as coming when called or walking calmly on a leash.[75] Second dominance-submission relationships, once established, are constantly tested and must be regularly reinforced.[77] Thus people, particularly children and the elderly, may not be able to retain their rank and are at risk of being injured if they attempt to do so.[75] Third, dominant individuals gain priority access to resources, but only while they are present, establishing dominance over a dog does not guarantee its behavior when the dominant individual is distant or absent.[75]
Electronic training involves the use of an electric shock as an aversive. Common forms are collars which can be triggered remotely, or that are triggered by barking, fencing that delivers a shock when a dog wearing a special collar crosses a buried wire, and mats that can be placed on furniture to deliver a shock. Some aids deliver an aversive such as a spray of citronella when triggered.[65] The use of electric shock aversives for training dogs is the subject of considerable controversy. Supporters claim that the use of electronic devices allows training at a distance and the potential to eliminate self-rewarding behaviour, and point out that properly used, they have less risk of stress and injury than mechanical devices, such as choke chains. Opponents cite the risks of physical and psychological trauma associated with incorrect or abusive use.[66]

Young puppies can’t hold their bowels & bladders for long. If you come home to find that they’ve had an accident in there it’s quite possible that they can’t hold it that long. Generally puppies can hold their bladder for about one hour per month of age. So your 3 month old pup can probably only hold their bladder for about 3 hours. If you’re going to be away at work for long periods of time see if you can get a neighbor, relative or dog sitter to come over to let your pup out during the day.
Based on the principles of social learning, model-rival training uses a model, or a rival for attention, to demonstrate the desired behaviour.[69] The method was used by Irene Pepperberg to train Alex the African Grey Parrot to label a large number of objects. McKinley and Young undertook a pilot study on the applicability of a modified version of the model-rival method to the training of domestic dogs, noting that the dog's origins as a member of large and complex social groups promote observational learning. The model-rival training involved an interaction between the trainer, the dog, and a person acting as a model-rival, that is, a model for desired behaviour and a rival for the trainer's attention. In view of the dog, a dialogue concerning a particular toy commenced between the trainer and the model-rival. The trainer praised or scolded the model-rival depending on whether the model-rival had named the toy correctly. It was found that the performance times for completion of the task were similar for dogs trained with either operant conditioning or the model rival method. In addition, the total training time required for task completion was comparable for both methods.[70]

"Cesar Millan Live!" is an international touring dog training lecture and stage performance where Millan presents his techniques and philosophy from his television shows and books in front of a live audience. The show consists of one-half lecture and one-half demonstration with local shelter dogs, in which he uses his pack-leader training techniques to modify negative behaviors.[29]
Before enrolling with a particular club contact them and ask if you can go to watch a class without your dog. This will help you decide if this is the right environment for you and your dog. Some clubs have waiting lists and you will need to book ahead, some accept people on a roll on roll off basis. Prices will vary from a joining fee and then weekly payments to a one off fee for a certain length of training.
