Firstly you MUST have the 2 boys sterilised asap. It will help with most of your problems and then I suggest we do a session. They also must get out for at least an hours walk everyday. If you are not able there are dog walkers who can do it for you. They should also sleep inside at night and after the boys are sterilised they will not mark inside. Then the barking and destruction at night will stop. Also if exercised regularly they will not be as destructive.
