How old is Benji? He could be an excited pee-er. My mom's cockapoo is exactly like this, she gets so excited that she whizzes everywhere, lol. He might out grow it, or he might never. When does he exactly pee? When he sees the person, when they say something, when they touch him? What will help if you get him to calm down first before allowing any interaction. No touch, no talk, no eye contact really helps, and when he is calm he will be less likely to pee. My mom's cockapoo is fine after 10 min of being ignored and won't excite pee when interacted with.
