I think ten weeks is a great age to start, and yes I would start from the instant you bring your new baby home. Silvia was also ten weeks old when we brought her home and we already had her boxes set up for her, so that's the first thing we did after introducing her to the cats. Since you will most likely need lots of treats in the beginning to motivate your pup to use the box, I would focus on very small treats that can be broken up. We used greenies, the kind that came in tiny little broken up pieces. It only took the smell of the treat to motivate her and they were so tiny that we could give her lots during the day. I hope your baby does really well with it. Good luck! And if you have any other questions about it, feel free to PM me.
