Riley's a talker. I don't know about other Saints, but he likes to grumble, moan/sigh, and bark. I'll tell him no, and he'll let out a long sigh. He used to bark and when I'd say, "Hush," he'd look right at me and bark again, just like he was talking back to me. He doesn't do that much anymore. He does like to grumble when he's not getting his way. He's very dramatic about it. If I'm not paying attention to him, he paws at me (he picked it up from Sadie who does it when she needs to go to the bathroom). Then, if his big ol' paw isn't enough, he'll sit right in front of me and bark a couple of times.
Sadie will bark is she's guarding me/our home. She has occasionally whined-to get outside to see a cat or dog (a few times) and once because she had to throw up (smart dog-I never knew her to whine, so I immediately took her outside... thank goodness-it was a mess).
