My sister's dog... I mean, I love him, but I'm usually the one left watching him while she's at work or at her fiance's house. And this damn dog will whine to be let outside, but if I don't go out to the backyard with him, he'll whine to be let back in. I let him inside, he's chill for like 30 seconds, then wants to go outside again, rinse and repeat. I don't think he's happy unless I'm out there with him--but I can't do that all day, because I have my own hobbies and obligations.
