Awesomedog has an unusual ability to open damned near anything. He can work zippers and buckles, certain types of doorknobs, and those airtight vault containers made for pet food.
Anything remotely edible inside a plastic container or with a plastic lid is fair game, but Awesomedog doesn't like to chew on metal or glass. For years, anything with a metal lid was considered safe. However, Awesomedog views the world as one giant food puzzle toy. Garbage cans, refrigerators, and jam jars rank alongside Kongs, Buster Cubes, and TreatStiks. The day Awesomedog learned to chew the lids off liquor bottles, I found him passed out on the couch with an empty bottle of Bailey's.
Fortunately there was only an inch left before he drained the bottle, but we now keep the liquor locked up because Awesomedog has yet to figure out how keys work.
