Where they completely house broken before they began doing this? How old are they? Do you let them out regularly? Have you had them checked for a urinary tract infection? 

Don't confuse urine marking with wanting to pee

If you find large puddles of urine on the floor it is more likely that the dog had to pee and couldn't or didn't want to go out. With urine marking the dog deposits a smaller amount of urine. Marking in the house is usually done to an upright surface such as a doorway, table leg or piece of furniture. The dog will lift his hind leg and mark urine on practically any object in your house. Quite often the object is something new or different with unfamiliar smells that has come into the house but not necessarily so. He is also likely to mark items that he feels belong to him such as anything that he has become possessive about including you. He thinks you are his possession and any objects related to you are also his possessions.For more info go here>>>
