Definitely consider getting him neutered as soon as possible to
see if this helps. He is maturing and it does seem to sound like
he is marking so you want to nip that in the butt quickly. If
you neuter him and he still does it invest in some belly bands
it will save you major frustration and embarrassment especially
when you are visiting others with him.
