lifting leg in house

Question
I have a 7 month male who seems to be marking his territory in the house! I am at wits end. He has been neutered but still lifts his leg. I sit for dogs while their owners are away. I think he is just being territorial but how can I break him of this bad habit? Thank you for your help.

Answer
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. Start at http://www.dogsbestfriend.com/

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.   You can pick him up with your hands behind his front
shoulders and hold him up with his back to you.  Keeping him far enough away
to keep his head from smashing into your face, hold him until he stops
struggling and relaxes.   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.
