Two of the most common causes of behavioural problems, is a deficiency in two things.
1. Exercise
2. Enrichment
These things need to be done on a daily basis, to prevent behavioural problems developing.
Both should be diverse, broad and varied.
The result of catering for both of these on a daily basis, is an outlet for both physical and mental energy, which are often underlying contributing factors in a vast array of behavioural problems.
