Even if you try to transition to the outdoors, your puppy will be confused because you will likely have items resembling potty pads lying around the house. Do you have pillows? Blankets? Sheets? Rugs? It’s not a stretch to think that your puppy, or an older dog, even, may confuse one or more of these items with plushy, soft potty pads and decide it would rather go there than outdoors. Just save yourself the headache and don’t use puppy pads.
Feed your dog a high-quality diet with appropriate amounts of protein. If your dog spends most of his days lounging in your condo, don’t feed him food with a protein level that is ideal for dogs who herd sheep all day. The money that you will spend on feeding an appropriate quality food will often be money that you save in vet bills later on. I recommend you always check with your veterinarian for the right diet for your dog.
One of the biggest mistakes new puppy owners make is expecting their puppy to hold it for longer than he is physically capable. The general guideline for puppy “hold times” is that each month of age equates to an hour of “hold time,” so a two-month-old puppy can hold it for roughly two hours. There are exceptions to the rule; your puppy should be able to hold it for slightly longer period of time at night as he gets older and you pup will need potty breaks more frequently when he’s playing.
Most people don’t have a problem being very clear about when they are unhappy with their dogs, but, they often ignore the good stuff. Big mistake! Make sure you give your dog lots of attention when he’s doing the right thing. Let him know when he’s been a good boy. That’s the time to be extra generous with your attention and praise. It’s even okay to be a little over the top.
Lindsay says of this study, "Schilder and Van der Borg (2004) have published a report of disturbing findings regarding the short-term and long- term effects of shock used in the context of working dogs that is destined to become a source of significant controversy ... The absence of reduced drive or behavioral suppression with respect to critical activities associated with shock (e.g., bite work) makes one skeptical about the lasting adverse effects the authors claim to document. Although they offer no substantive evidence of trauma or harm to dogs, they provide loads of speculation, anecdotes, insinuations of gender and educational inadequacies, and derogatory comments regarding the motivation and competence of IPO trainers in its place." 
Consistency and Patience. Never scold or punish your puppy for mistakes and accidents. The older your pup gets, the more he will be able to control his bladder and bowels. Eventually your pup will have enough control that he will be able to "hold it" for longer and longer periods of time. Let your puppy do this on his own time. When training is rushed, problems usually develop. Don't forget, most puppies are not completely house trained until they are 6 months old.
Classical conditioning (or Pavlovian conditioning) is a form of learning in which one stimulus, the conditioned stimulus, comes to signal the occurrence of a second stimulus, the unconditioned stimulus. Classical conditioning is when a dog learns to associate things in its environment, or discovers some things just go together. A dog may become afraid of rain through an association with thunder and lightning, or it may respond to the owner putting on a particular pair of shoes by fetching its leash. Classical conditioning is used in dog training to help a dog make specific associations with a particular stimulus, particularly in overcoming fear of people and situations.
With Ilusión Millan, his former wife, he founded the Millan Foundation – later renamed the Cesar Millan Foundation and currently called the Cesar Millan PACK Project. The foundation was established to provide financial support to animal shelters and organizations engaged in the rescuing, rehabilitating, and re-homing of abused and abandoned animals, and to fund spay/neuter programs to help reduce dog overpopulation. It aims to "improve the health, happiness, and harmony of dogs and people – while helping both species learn from and support each other." Among other projects, the Foundation worked with Yale University to create a children's curriculum based on his work.
Understand your puppy's particular breed behavior and needs. Research your dogs breed traits and special needs or any behavior that you should be aware of and look out for. For example, If your puppy is a tiny little chihuahua, their bladder will be very small and they will need to urinate more frequently; accidents will happen even if they are well trained.
Suppose you consistently praise your puppy for their actions, while potty training. Then say your dog has an accident. Do not praise you dog immediately. Instead, take your dog outside and wait for it to go to the bathroom. When it finishes doing its business, take it inside, and keep it in a separate room while you clean up the mess. After this you should act disappointed in your dog, but only for a few minutes. Keep you and your dog motivated to potty train.
Learned helplessness occurs when a dog ceases to respond in a situation where it has no option to avoid a negative event. For learned helplessness to occur, the event must be both traumatic and outside the dog's control. Family dogs that are exposed to unpredictable or uncontrolled punishment are at risk of developing disturbances associated with the learned helplessness disorder. Punishment which is poorly coordinated with identifiable avoidance cues or response options, such as when punishment takes place long after the event, meet the criteria of inescapable trauma.
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.
