Marian Breland Bailey played a major role in developing empirically validated and humane animal training methods and in promoting their widespread implementation.[14] Marian was a graduate student under B.F. Skinner. Her first husband Keller Breland also came to study with Skinner and they collaborated with him, training pigeons to guide bombs. The Brelands saw the commercial possibilities of operant training, founding Animal Behavior Enterprises (ABE). In 1955, they opened the "I.Q. Zoo" as both a training facility and a showcase of trained animals. They were among the first to use trained animals in television commercials, and the first to train dolphins and whales as entertainment, as well as for the navy.[14] Keller died in 1965, and in 1976 Marian married Bob Bailey, who had been director of marine mammal training for the navy. They pioneered the use of the clicker as a conditioned reinforcer for training animals at a distance.[13] ABE went on to train thousands of animals of more than 140 species.[14] Their work had significant public exposure through press coverage of ABE-trained animals, bringing the principles of behavior analysis and operant conditioning to a wide audience.[15]
One of the easiest ways to prevent accidents is learning to recognize when your puppy needs to go out. Most puppies will sniff the ground when they’re getting ready to potty, but there are many other more signals that happen prior to sniffing. Puppies that pace, seem distracted and walk away from play are subtly signaling that they have to go out. If your puppy tries to sneak out of the room, take a potty break right away.
Konrad Most began training dogs for police work in Germany, and was appointed principal of the State Breeding and Training Establishment for police dogs in Berlin, where he carried out original research into training dogs for a broad range of service tasks. At the outbreak of war in 1914 he was charged with organising and directing the use of dogs to further the war effort. He headed the Experimental Institute for Armed Forces' Dogs during the Second World War, and afterwards ran the German Dog Farm, a centre for the training of working dogs, including assistance dogs for the blind. He played a leading role in the formation of the German Canine Research Society and Society for Animal Psychology.[10] His 1910 publication, Training Dogs: A Manual, emphasised using instinctive behavior such as the prey drive to train desired behaviors, advocated the use of compulsion and inducements, differentiated between primary and secondary reinforcers, and described shaping behaviors, chaining components of an activity, and the importance of timing rewards and punishments. The book demonstrated an understanding of the principles of operant conditioning almost thirty years before they were formally outlined by B.F. Skinner in The Behavior of Organisms.[11] While publishers of the 2001 reprint warn that some of the "compulsive inducements" such as the switch, the spiked collar and the forced compliance are unnecessarily harsh for today's pet dogs,[12] the basic principles of Most's methods are still used in police and military settings.[13]

Potty training seems like a daunting task! It really does. I know people who avoid getting puppies just to skip this process, and in some ways I totally understand that! Puppies really are a LOT of work, and it is not just potty training! It can be varying aspects of housebreaking, teaching your puppy manners, making certain that it is well socialized, addressing early issues like persistent whining or separation anxiety before they become permanent problems, and tons of more areas to make sure that your puppy is on track to being a happy, healthy, well-behaved dog.
It also helps to teach your puppy a “potty phrase” when you take him outside for a bathroom break. A potty phrase is a way to gently remind your puppy what he needs to do when he’s outside. It’s a big help during the potty training phase of puppyhood and you can continue to use for the rest of his life. Pick a phrase like “hurry up” or “go ahead” and say it softly right as your puppy eliminates. In time your dog will associate the phrase with the act of elimination, so you can say it when your puppy gets distracted and forgets what he needs to do outside.

Pups between the ages of 9–12 weeks who were permitted to observe their narcotics-detecting mothers at work generally proved more capable at learning the same skills at six months of age than control puppies the same age who were not previously allowed to watch their mothers working.[56] A 2001 study recorded the behaviour of dogs in detour tests, in which a favorite toy or food was placed behind a V-shaped fence. The demonstration of the detour by humans significantly improved the dogs' performance in the trials. The experiments showed that dogs are able to rely on information provided by human action when confronted with a new task. Significantly, they did not copy the exact path of the human demonstrator, but adopted the detour behavior shown by humans to reach their goal.[57] A 1977 experiment by Adler and Adler found that puppies who watched other puppies learn to pull a food cart into their cages by an attached ribbon proved considerably faster at the task when later given the opportunity themselves. At 38 days of age, the demonstrator puppies took an average of 697 seconds to succeed, while the observers succeeded in an average of 9 seconds.[58]
Pay attention to your puppy while you're waiting for him to do his business. Sometimes, especially in the beginning, you might have to wait a little while before your puppy gets around to using the toilet. You can do some exercises or some light gardening, but keep on eye on your puppy because you'll want to take him back in as soon as he's finished.
Individualised training is used with dogs that have an urgent or unique training problem such as fear, hyperactivity, aggression (and other related problems), separation anxiety, biting, excessive barking, insecurity, destructive behaviors, walking difficulties, and inappropriate elimination.[84][85] This type of training would normally be undertaken where the problem naturally occurs rather than a class situation. Class training can be effective in encouraging socialization and play with a peer group. Classes are often offered at a more affordable rate and can cover both problem behaviors and teach new skills. Classes can range from puppy and beginner training to more advanced training and skill training such as performing tricks or therapy work.[86]
Remember that training is an ongoing process. You will never be completely finished. It is important to keep working on obedience training throughout the life of your dog. People who learn a language at a young age but stop speaking that language may forget much of it as they grow older. The same goes for your dog: use it or lose it. Running through even the most basic tricks and commands will help them stay fresh in your dog's mind. Plus, it's a great way to spend time with your dog.
