Seems many have wondered: why “dog”?
To dog: As in to track or to hunt (English from the 16th century)
Weather dogs: a short segment of rainbow on the horizon (Anglo-Cornish)
“The phenomena of false suns which sometimes attend or dog the true when seen through the mist.”
~ Folk-etymology by Abram Palmer (1882)
“Of obscure origin.”
~ Oxford English Dictionary
