From what I've read a while back it was not possible for the PC to be a hellhound in the same way as Hellhound Syri or Ciaran, you had to have extra canine features such as face shape and stuff. Since the racial score stuff has recently been altered, I was wondering if it's now possible?
For NPCs, Hellhound is Treated Ausar. For the player, it's Canine/Lupine + Demon. It was tricky to get in Flash, because of the way Demon was calculated. After the conversion to JavaScript, for some reason, the calculation for Canine/Lupine was changed in such a way as to make achieving it impossible.
After the overhaul, Hellhound is possible again, but you still need to be very canine. The Racial Score system is still being worked on, so this might not be final.
Assuming it works as Flash, the easiest way is probably to start will full Canine/Lupine, then add Demon Horns and Wings. You could then add a Demon Tail, Demon Arms/Legs or hooved legs. I also found that Demon Tail-Cock(s) also count, regardless of tail type, but I don't think it's possible to get just the tail-cocks without a console command.
Open the console with F12 (if on a Browser)
type or copy/paste
pc.shiftAnyCock (pc.tailCock, [GLOBAL.TYPE_DEMONIC]);

That didn't work in Flash, but apparently it does now. I'm surprised. The notes said genital requirements were mostly removed.
Of course, if you don't want a penis, you'll have to do something else. There is no Demonic vagina.
Testing with the console, it's looking like Eyes and Tongue don't actually count. It's the Demonic penis that's pushing me over the edge.
I kind of wish you could get a more detailed breakdown of what parts are qualifying you for each race.
No hellhound treatment path has been written as-of-yet. If it were to become a thing, it would be a community-submission like cowmazon, cum cow and faux cow.
