Yes and no, really. It was complicated to talk about since unless they're communicating via Personae (which was a long shot regardless), she likely wouldn't understand that he used it to help him summon his Persona. Hell, she would likely be confused by that in general. It wasn't like he could tell that she was one, too.

He barked once, meaning 'yes.' It had helped him communicate with Chidori, after all. Maybe it'd help here? The mention of his name made his tail wag. Yep, that's him alright!
