• Whenever you greet your dog, especially after a long period of absence, keep it calm and mellow, don't get him all excited.

• Do not punish or harshly correct your dog for this behavior. He's not doing this on purpose. If you catch him in the act, simply interrupt him and praise him when he stops - but don't punish him.

• Limit his intake of water to help him control his bladder especially whenever a situation is coming up which would normally result in urination.
