Fun! Source article also covers meows.

This doesn’t make much sense because it purely looks at spelling, and not at pronunciation. We use ‘woef’ in Dutch as well, which is pronounced like, and probably has a common origin with, German ‘wuff’ and English ‘woof’.

French ‘ouaf’ is also pronounced essentially the same as Dutch ‘waf’, likely also not by accident.

This map is pretty much meaningless.

How is voff so much different than woof? It's pronounced like exactly the same.

French is "ouah ouah".

German can be "wuff wuff" or "wau wau".

I doubt the rest is correct

Is must have been really hard to make that chart. Imagine listening to lots of dogs from different places

And just like that I remembered about the Arbitrary Nature of Linguistic Sign I read about 20 years ago.

The one for the Netherlands is wrong: dogs say "blaf blaf" here, not "waf waf."

How, how?

Turns out they bark the same.
