The collar idea works, just reword some of the text from the Amulet of Natural Armor for flavor.Rothe said:Why not a magical band around a leg or a collar that provides an AC bonus, not enough cash?
That sounds about right. And I've seen doggy plate armor.jefgorbach said:Dont see anything wrong with the idea of providing his little furry friend with some extra protection, after all it was done for war dogs/horses IRC and modern pets are routinely outfitted with "cloth armor".
However I imagine (and suggest ruling) the animal needs both time to adjust and training to move unhindered in anything above cloth armor.
Do you also reduce the effectiveness of armour for halflings and gnomes?Rothe said:I can't see it working like armor would on a person. You need a certain minumum thickness to help stop a dagger thrust etc. On a small creature it just becomes too encumbering.
