I've never specifically looked for it, but to my knowledge the dynamic data for all the stats of a pet do not exist. The reason you get all those stats when possessing the minion is because it's using the player dynamic data, and during possession the pet is the player.
Having an (admittedly low-level alt) pet character, all that data would be great to easily access but I do not know of any dynamicdata to look. You can check in eq2ui_dynamicdata.xml and see if there's anything pet-related that you'd like in there. Whatever isn't available there I would put a /feedback in and request data for.
