I had avery hard time housebreaking Ginger. For being such clean dogs, Eskies are very hard to housebreak. I had to keep her leashed almost all of the time, when she wasn't crated, and as soon as I saw her squat (or show signs of wanting to) I would pick up the leash and walk her out the door. I guess the main thing is, until he shows signs of understanding that he needs to tell you when he wants to go out, you will have to keep an eye on him at all times, when he is not crated. If he is just going whenever he feels he has to, bells on the door won't help. Once Ginger understood what was expected she would go sit against the front door. If I wasn't paying attention, she would walk into the den and stare at me real hard (you have an Aussie, you understand that ), but first they have to know to get your attention first. They need to know that going potty is something you do together. (Hmmm, is that why they always follow us into the bathroom?)
