Remove implication: puppy -> dog

Reason: wolf puppy should not return dog.

Actually I believe puppy is dog specific, and "pup" would be the correct term for referring to wolf cubs.

If you want to make it more general you might want to switch the naming of the tag from "puppy" to "pup."

I think it's going to be a little tricky at times to tell if it's supposed to be a dog or a wolf, so maybe the vagueness might be helpful?
