Seriously, though, we'll come home from the store with a grocery bag full of other things plus a new toy, and he'll sniff the bag while I'm putting away groceries, even when I tell him to get off the counter. He knows when I pull out the toy. Once, I had a big trash bag of clothes my parents were getting rid of that I was going to go through before they were donated. Buried near the top of the bag was a frisbee- brand new, so no "dog smell"- stuck in there for Casey. He nosed through the bag and found it. I was amazed.
Do you have a "heavy-duty chewer"? What pacifies them?
