I think using a gate is the best idea for you and your Yorkie's. I really do not know how to retrain the dogs from using the couches . My 2 are inside most of the time, but when I do take them on walks they usually love to roll all over the grass. I do not let them go out after it has rained . But, if their paws do get dirty i'll just wash them off in the sink. They are small enough to just pick up and do this without too many problems. I use pee pads in the hallway. They do fine . But, have seen one of them pee on the bathroom floor . So we have to keep doors closed to prevent this from happening.
