Here’s the thing, a bark is the sound made by a dog.  Isn’t it?  Apparently, it can also be from a fox or a seal

Not necessarily.  A man or woman can bark orders, especially if they are in the army.

And then, their bark might be worse than their bite, this usually refers to newspaper editors and school teachers.

You can theoretically be barking up the wrong tree, and believe me, I’ve done that a few times myself.

People can be barking mad.  Just go to any old spooky hospital that is named Belleview, and has a basement.  How do I know this, I’ve seen a lot of old black and white movies.

Then there’s that other type of bark, the outer layer of a lot of trees, and can be very useful as a top layer of a garden to keep the moisture in.

It can be thin sheets of chocolate with a thin layer of nuts or other confectionaries.

You can bark your shins, that is, scrape the skin off when you trip over a tree with bark.

Or just to complicate matters, there is also a barque, usually a three-masted sailing ship, though you don’t get to see many of them these days.
