I think our dog is pretty smart. That is, she knows how to communicate and tell us what she wants.
Last night hubby and I were sitting on the couch watching TV, and doggie was lying on the floor. She got up and looked at us and wagged her tail as if she wanted her nighttime biscuits; she'd already had them, though, so I told hubby she probably wanted to go out. He got up to let her out, at which point she ran around the coffee table, jumped onto the couch where he'd been sitting, settled down and put her head in my lap, then looked up at him with her big brown eyes as if to say, "What?" Apparently doggie was trying to tell us that hubby was sitting in her spot on the couch (which he was) and she wanted to sit there! While laughing, hubby called her a conniving little mutt. I thought she was pretty smart.
Not to let the dog get the last word hubby squeezed in next to her, which she thought was just fine. She didn't move, of course; after all it was her spot. But she's willing to share. She's a snuggly dog and likes to be close to her folks.
