Tbh, I couldn't care less about being able to change your face with the upcoming patch. They need to at least have a summonable Mabari.
I get it if they don't want to make it a spell as they did in 2 (with only 8 spells on consoles and the inability to cast more) but even something like a ring that summons one (maybe have a cooldown of 60 seconds in case it gets killed). That would make me happy.
A war table mission after you help the ruler(s) of Ferelden would be a good way to obtain it. Heck, the dog we get could even be a descendant of the Mabari owned by the HoF

How awesome would that be?
EDIT:
Yes to a mabari -- or any other kind of pet, from a wolf, to a wild cat, to a bronto (brontos are cute and would made awesome tanks!).
My Cousland's dog was named Ser Riley; my Dwarven Noble's, Stonecutter; and my Hawke's, Dane, after the legendary Alamarri warrior.
This is an excellent point. Expanding on my original idea, they could have a different war table quest for each option. Possibly making them exclusive to one another to add impact to your choice. After all, having a dog, a wolf, a wild cat, AND a bronto would be cool, but it would make the pet you chose less special
