Did I claim it was true? It's just a song. And I don't give snopes any traffic, ever.
I was not implying anything bad.
I just thought you might enjoy the history behind it.
I first read it as a Welsh legend.
Snopes may suck but they had the best list of all legends involving that, sometimes it was not even a dog and wolf.
Unfortunately, I cannot copy and paste the list of variants from Snopes so you don’t have to go there to read it.
It is really a fascinating and powerful universal tale.
