I was inspired by the shoes sold by Dog Mocs, and wanted to make something similar for my dog. Went through a few iterations, starting from hand-drawn shape and glued-together fabric to a CAD-designed, 3d printed template and, of course, leather. Dog's name is Melody, she can walk and run almost like normal in these shoes, without them shifting around.

Next step is to parameterize the CAD design, try out different leathers (thinking goat and deer) and see if any of the neighbours with smaller dogs might be willing to let their dog be models.
