marking in the house

Question
We have a 10 month old mini pin and are having the hardest time stopping him from marking in the house. He lifts his leg. He has gone on our curtains, couches, floors, toys and more. He is kennel trained, but we can't keep him out very long or he pees on something. We don't know what to do to stop him. When I catch him I scold him, but I am still not sure of the proper way to scold him, I keep hearing different things. Can you help?

Answer
Neuter him if not already.  It is no cure all, but a big help in these cases.  It also reduces his chances of cancer later in life.  

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.

You need to keep a close eye on him when he is out of the crate.  Use closed doors or gates to keep it in the same room as you are, and perhaps as I do, a short chain fastened to the computer desk.  If you catch it in the act, give it a sharp ''Ah, ah, ah!'' and take it out.  When you can't watch it, crate it.
