Pretty much what everybody else is saying.
Be consistent. This means you and your wife. Make sure both of you are doing the SAME things.
Give it time. My German Shepherd only took a day and 1/2 to become crate trained. Then he loved his crate, it was his. BUT, he was 8 weeks when I got him. Your is 6 months, it is going to take a LOT longer for your dog to unlearn bad habits.
Learn your breed. Every Great Dane I have known seem to be potty trained from birth and they can hold it forever. It just seems to be in their nature. My shepherd is intent on doing what I want, he needs a job to do. Turning potty training into a task was best for him. Learn about maltesses. Especially from people who own them. Ignore people that only have positive things to say about their breed. Talk to people who will tell you the good and the bad.
Maltesse.... Are those even dogs
