If you've never visited Emma the GBGV's blog, check it out and you'll know what I mean. There are numerous photos of well behaved dogs baking, reading, using computers, and other things mine wouldn't do if I offered them a whole box with cookies.
Once Ellie showed interest in the box, BooBear wanted to look too. He's a very hungry little fluff-ball, and a box someone else looks at might contain stuff to eat. He has no idea how right he is, LOL.
I think he's saying, "I smell food."
