Males marking

Question
I have three shith tzu's.  Ali is 3, Snookie is two both female and Thor who just turned one.  Thor is peeing everywhere.  What can I do about this.  He pees on end of the couch, he pees on the corner of the bed.  What can I do to help this situation? My two females are not fixed yet. I actually bought Thor to bred but he has some male problems (he never dropped) therefore he is going to be fixed.  Also is a this breds trait to eat there own droppings?  It seems i cannot break them of this habit.

Answer
Getting him fixed should help.  You also may need to give your dogs better leadership.  

The key to most behavior problems is approaching things using the dog's natural instincts.  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.

I don't know if it is more common in them.  Best thing to do is clean them before they have a chance.
