My dog Connor is so strange.
I live in a house that was built in the 1880's and I am never quite confident of the water pipes, as I am sure they are lead-lined. So I tend to drink bottled water. It becomes a battle of wills between me and the dog. As I drink, he sits and stares at me. All he wants is the bottle.
Once I am finished, I throw the empty bottle down the hallway and he romps after it and begins the process of taking it apart, bit by bit. Once he's gotten the plastic pieces off, then he starts on the label. It's a great source of entertainment for him.
This dog has quite a selection of toys, including several iterations of "Lambie" and a pink pig. But what he likes the most is a plastic water bottle. That counts for recycling, doesn't it?
