Wetting problem

Question
I have a 2 year old American Cocker that will jump up on our couch and wet. Even after he was just out.  We have cleaned this couch and sprayed with a commercial product.  What can we do to help stop this behavior?

Answer
Having a good pack structure reduces such problems.  The dogs see all the
people and dogs in the household as a pack with each having their own rank in
the pack and a top dog.  Life is much easier if the 2 legged pack members
outrank the 4 legged ones.  You can learn to play the role of top dog by
reading some books or going to a good obedience class. A good obedience class
or book is about you being top dog, not about rewarding standard commands with
a treat. Start at http://www.dogsbestfriend.com/

That is his way of showing he is top dog, and the couch is his.  top dogs get the best and highest places to sleep.  It is called marking.
Catching him in the act of marking calls for stronger corrections than the
otherwise effective "Bad dog!".  When it misbehaves, throw it on its back, and
growl "Bad dog!" right in its face.  Hold it down until it lifts one back leg
to show submission.  Others like the squirt bottle.  Fill it with water
and a little vinegar or lemon juice.  Give it a squirt in the face as soon as
it misbehaves.  Dogs hate that.
