Sometimes dogs will mark their territory by urinating. If they have a dog, your Cavachon could be trying to become dominant over their dog. Another reason is that your dog could be afraid of your friends/family because they could scare or irritate him in a way that scares him. Some dogs urinate when they are afraid by someone teasing them (such as 'flappping' the mail-slot loudly).
