We got Marley a new toy, a treat ball. She absolutely loves it. It has an insert where I can record my voice, which kind of weighs the ball a bit. I have not recorded anything, because I think it would drive me nuts.
This toy will keep her occupied for about an hour. Unfortunately, she'll end up hiding it and I have to spend an hour searching for it.
I've also discovered she loves bubbles. Yep, the same bubbles we used to play with as kids. She goes absolutely crazy and starts barking at me as soon as she notices the bubble bottle. As soon as I blow the bubbles she starts jumping and trying to catch them before the dissipate. As soon as I can I'll take some pictures.
