Greta is by far the most well behaved dog we have. Not that the others are not well behaved, but Greta has this regal attitude and is so laid back and quiet.....and is this way no matter where we go EXCEPT the MIL's house. For some reason whenever we take her to MIL's she turns into this gittery, whinny, running you over, crazy dog, plowing through people, whacking everyone with her tail, pacing and refusing to sit still. I don't know why. It's like she's her normal self, walking to the door, walk through the door and she's a completely different dog. And of course, since MIL never comes to our house, she doesn't see the calm, super cool Greta and so when I say she doesn't normally act like this, she doesn't believe me.
