Dog Sandworm Costume

My boyfriend and I are going to be Beetlejuice and Lydia. So our dog is kinda like our baby and we decided to include her as the sandworm. Gidget was really well behaved during all the measuring and trial and error sort of stuff. Anyway, it was kinda tricky but I'm pleased with the outcome. If anyone has any suggestions that'd be sweet! But I want her to be as comfortable as possible so I didn't put a tail or anything else on it. Also, we think its funny because her tongue is almost always poking out :p
