He is still very young, but if you can, spend some time just watching him and you will be able to learn 'his' signals. Brody and Mia are older...almost 3 years old, but both have a 'signal'...their signals are not something a 'normal' person would notice, but I watched both carefully when they first came to live with me to pick up on any variation in their behavior, especially when I thought it was getting near the point where they might need a potty break. If they have an 'accident' of any kind, I figure it is MY fault for mis-reading/missing THEIR signals. We have puddle pads, too, in case something goes wrong, or hurricanes, etc...use of which I do not consider an accident...so when I miss a signal and/or they need a puddle pad during the night, etc., they get praise for using the pad, too. Keep at it. You will get there.
