The foundation of training should be based on positive reinforcement. Positive reinforcement is the process of giving a dog (or person!) a reward to encourage the behavior you want, like getting a pay check for going to work. The idea is not to bribe the behavior but to train it using something your dog values. Avoid using punishment such as leash corrections or yelling. Punishment can cause a dog to become confused and unsure about what is being asked of him. It is important to remember that we can’t expect dogs to know what they don’t know – just like you wouldn’t expect a 2-year-old child to know how to tie his shoes. Patience will go a long way in helping your new puppy learn how to behave.
If your pup barks: Some dogs have the habit of barking at other dogs while on a walk. Oftentimes, this behavior comes as a result of lack of exercise. Make sure your dog gets the proper amount of mental and physical stimulation for his age and breed. If this is still a problem, use the same process as you would if your dog is lunging, as described above — create distance and offer treats before he starts to bark, so every time he sees a dog he gets used to turning his attention to you.
It typically takes 4-6 months for a puppy to be fully house trained, but some puppies may take up to a year. Size can be a predictor. For instance, smaller breeds have smaller bladders and higher metabolisms and require more frequent trips outside. Your puppy's previous living conditions are another predictor. You may find that you need to help your puppy break old habits in order to establish more desirable ones.
