Hey there, sorry to breathe life back into an old post but I was having this same issue with a game I'm currently in. There's a spell-less ranger in the party and we both really liked the idea of a stag mount, so what we ended up doing is just taking a horse animal companion, switching it's strength and dexterity, and naming it a "Great Stag." Does that sound like it works? It just seemed like the easiest thing to do.
