In Arthurian Mythology, Sir Tristan had a 'tiny, beautiful, brightly coloured dog' called Petitcreiu who wore a little bell around its neck that brought happiness to whomever heard it. It was a beloved companion pet of Tristran's sweetheart, Isolde, who tore the bell off it.
Now, this thing could not move anything except its head.
It did not sleep.
It did not eat.
It is exclusively referred to as 'it'.
It's heavily implied to be immortal.
I'm also starting to see why it wore that bell.
(There is some serious debate about whether Petitcreiu was an actual living creature (probably a fae-thing) or a statue/toy, but it's Arthurian so an immortal fae dog would absolutely track)
