I understand I'm NECROing this(big time) but I was having similar thoughts for my dog(after I finish my MC suit(haven't even started)) But I was mainly wondering what the chances of scaling say the Arbiter's helmet down to fit my dog's head? I don't have exact specs of his size just yet but I'm mainly interested if if it's even feasible using the pepakura (the picture is my dog and he is rather small, beefy but small.) I know I can dress him as I've put jackets, goggles and all types of things on him(my sister has a French bulldog as well and bought it clothes I'll never do that lol but some spiffy armor.. well... lol) and he doesn't mind or care unless it's on his feet(he likes to lick the bottom of paws and the way he's built he cant lick anything else(seriously).) So really my question is, can something be scaled down to his size?
EDITED: I did some rough(very rough) measurements my dog is exactly 2feet long(from nose to tail or lack of tail), 1 foot tall from his head to his middle(his rear sits up higher about 2 inches making him 1'2" in the back) His head is 5 inches width wise and the length is 7(this isn't exactly exact so there is about an inch or 2 that will need to be added or taken away)
