As a person who often sleeps past noon when she doesn't have work or class? I consider that rude. It's one thing if people are having a loud conversation outside of your room when they know you're asleep (and even then, I'd be extremely hesitant to ask them to move the conversation if I were a guest), but dogs and dogs, and you can't expect other people (much less animals) to accommodate your weird sleep schedule if you're a guest.

And it's also rude as fuck to shout in someone else's house.
