Positive and consistent training, both in attitude and action, is needed so that your new pet will know what is expected of it at any time. If the expectations are unclear for your new pet this may lead to a wide variety of problems, such as unruly behavior, disobedience, and even aggression. Undesired behaviors such as nipping, excessive mouthing, and jumping up should be discouraged by teaching appropriate or acceptable alternate behaviors.
There are many different reasons why dogs bark. In most cases, the barking is actually a signal that another behavior problem exists and, if that problem is addressed, many times the dog will stop barking on his own. It is extremely important to know why a dog is barking before trying to control it.
