Where to look for a Slavering Dream-Hound?

Hello dear friends.
I searched days and nights, everywhere in the Neath and beyond, but I never was to find the fabled Slavering Dream-Hound.
Would someone be kind enough to whisper in my ear some advice on where to find this dreamy companion?

Dear friends, thank you for the quick replies. The solution was quite right under my nose. :-)
My Slavering Dream-Hound is quite a very happy puppy…

Sorry to revive an old thread, but could someone point me in the right direction here, too?

There is a certain beast found at zee that needs to be fed Empyrean Redolence (Fate-locked) and bred.
