The first step to a well-behaved pet is to fully understand its behaviour.
Finding out the cause of unwanted behaviour allows you to solve the problem from your pets point of view, rather than trying to treat the symptoms with unkind methods.
Most behaviour problems are natural behaviours exhibited at an inappropriate time or place. Treatment often involves providing for the pets behavioural needs, such as staying safe, or needing to live as part of a social group, and offering something else to do at the time of the unwanted behaviour.
An owner who solves the problem for the animal will have a calmer pet with a more tolerant disposition. In addition, finding out how to get your pet to do what you want it to do, rather than trying to force it to behave, results in a long lasting cure and, a stronger bond between you.
