I would put a belly band on him. And from what I hear about potty training, peolple can quit too soon. They think their baby is trained when he's not and quit with the training. Later on he's worse than he was months ago. Now I'm sure that's not everybody, but something to consider. He's a male and could possible be marking. I would be very consistent with the belly bands/training until you're sure he's 100%!! Hope that helps. My knowledge from the knowledgable
