What does ruff mean in dog?

"Ruff" doesn't really mean anything specific in dog language. It's a word we use to describe a dog's bark, often a loud, harsh bark.

Here's why it's a bit tricky:

* Dogs have different types of barks: A "ruff" is usually a deep, throaty bark, but dogs also have other types of barks, like yips, howls, and whines.

* Dogs bark for different reasons: The meaning of a bark depends on the context. A "ruff" could mean a dog is warning, playing, or even greeting you.

So, while we use "ruff" to describe a specific type of bark, it doesn't have a single meaning in dog language.
