OMG! I must have this for Kira! I really need to get back into leatherworking. She'd look so awesome in that.

Sorry, carry on.

If you have PP2014, you should pretty much just be able to model it fitted to the dog and then go into the fitting room and transfer rigging to the armor. Depending on how many parts it has, some may need some movement morphs so they don't distort too much.
