Hoo boy, you ain't kiddin':
The term is derived from Latin Cynosura (Ursa Minor), from Greek kynosoura (dog's tail), ultimately
from the Indo-European root kwon- (dog) that is also the source of canine, chenille (from French chenille: caterpillar, literally, little dog), cynic, kennel, canary, hound, dachshund, and corgi.]

I hadn't looked at it yet; thanks!

From the "other" OED (prize of half a chewed doggie bone to whoever figures that out):
canary
1584, of the wine; 1655, of the songbirds (short for Canary-bird, 1576), from Fr. canarie, from Sp. canario, from L. Insula Canaria "Canary Island," largest of the Fortunate Isles, lit. "island of dogs," (canis, gen. canarius) since large dogs lived there. Hence, the name of the little bird from the island. The name was extended to the whole island group (Canariæ Insulæ) by the time of Arnobius (c.300).
