There's no particular reason the magic couldn't just make (real, permanent, ordinary) dogs out of nothing.
Generally it's actually fairly clear in the description when things are being forged whole-cloth out of magic versus being called to the caster and bound to service. Sometimes you need a catalyst; many undead require corpses in the description (though not in-game) for example, though those which call things from the Underworld sometimes just yank them out.
I can only speculate of course, but probably because the Oracle chassis is
I wanted something with high Astral, with Fortuneteller, and also that was very alien in its nature and potential mindset. The Oracle, as a Pretender God, is nearly as distant from a human thought structure as any of the Void Gods. It's a spirit bound to a magical well that speaks through a series of crippled and blinded little girls that are ritualistically drowned in its waters. That's kind of horrifying, but in a way has the lowest impact on Taylor.
Not to make too fine a point of it, but the Oracle is a cheapgod for MA and LA Arcoscephale, as well as MA Pythium.
