Do you know much of the history of what we now call "dogs"? For instance, the fact that "canine" as a species is what has been used to breed what is modernly referred to as "dogs"? Wild animals like coyotes and wolves. Where things like "Saint Bernard" or "Doberman Pincer" or "Dalmatian" of even "mutt" didn't even exist "in the beginning". So, to state that "dogs" have any sort of intrinsic or natural role in "creation" (as a reference to "when things were created") doesn't make much sense. Humans crafted them. Humans created them. Therefore, if they have any sort of "role" as pertains to humans it is because we bred them for it. The act of creation was most certainly ours, if we're looking to attribute it to anyone/anything.
Yes, I know the developmental history of dogs.
From my advaita perspective, there is only One and the part of that One which are humans helped develop dogs to fill a spiritual ecological niche.
