They all go through that stage, don't they. I know Dublin is right now!!!
We once lived in a house that had a mail slot on the front door, and the mail landed on the floor of the foyer. One of my Shelties shreaded an entire days mail one time!! I swear he wasn't alone but for a few moments, either!!!
Then someone posted on here once about their dogs white poo, only to post later (I'm sure after a hefty vet bill!) that it was ingested paper! lol
As my husband keeps saying, 'good thing they're cute!'
