Problems...

Question
I have a Shih Tzu that is 5 years old.  He was very easy to house train, however within the last couple of months, he has started "marking his territory" inside the my house, my boyfriend's house and my parent's home.  He only does it when he is left alone.  At my house, he does it to one particular chair by the door; at my boyfriend's house, he does it to his recliner; at my parent's house, he does it to the sofa near the front door.  We let him out regularly.  Please help!  Thanks!

Answer
5 years is a little old to be starting that sort of a thing.  Has anything changed, perhaps more of the boyfriend?  If he is only doing it when nobody is around, crating him should work.  Other dogs may not be as bad as the young Labs I am plagued with.  Still your house and dog will be much safer with the dog in a crate when you are away.  The dog may be happier in its den than loose in the house.  It relaxes, it feels safe in its den.  It rests, the body slows down reducing the need for water and relieving
its self.  Dogs that have been crated all along do very well.  Many of them
will rest in their crates even when the door is open.  I think the plastic
ones give the dog more of a safe, enclosed den feeling.  They are harder for
dogs to open too.    Metal ones can be put in a corner or covered with
something the dog can't pull in and chew.  Select a crate just big enough for the full grown dog to stretch out in.

Leave it some toys.  Perhaps a Kong filled with peanut butter.  Don't leave
anything in the crate the dog might chew up.  It will do fine without even any
bedding.  You will come home to a safe dog and a house you can enjoy.

Accidents and damaged possessions are the fault of whoever was watching the puppy.  When you are watching it, immediately correct it as soon as it goes for anything except its own toys.  In a quiet, but firm voice ''Bad dog, its name drop!''.  Gently remove what ever and replace it with one of her toys, or if older, hold eye contact until the puppy drops it.


A dog that has not been crated since it was little, make take some work.
Start out just putting its toys and treats in the crate.  Praise it for going
in.  If you have been able to trust it with any bedding, put that in the crate.
Feed it in the crate.  This is also an easy way to maintain order at feeding
time for more than one dog.

Use the crate only when you must  I have a short length of chain fastened to
my computer desk.  With more mats around the chair mat, this gives a place
where the puppy is with me, but about as controlled as in the crate, while
still allowing me to get some work done, or at least answer All Experts questions.
