My dog goes inside for attention?

I believe my dog goes potty inside for attention He(8 month old maltese-poodle). He went when he was barking/growling/running around me roughly when i didn't pay attention to him, since when they act bad, you are supposed to not pay attention, right? He also goes ANYTIME I put him in his crate, and when I take a shower he goes. What do I do? :/
