...and wondered if you'd ever tracked anything down. I also have w-i-d-e dogs. From what I've seen in web-browsing, pipers with our problem recommend getting a pair of comfy Rockports/shoe of choice (oxford/brogue/wingtip), finding a good ghillie brogue photo, and then visiting a good shoe repairman to get him to alter the shoes to match the photo.

I found the idea too late to try it for my buddy's wedding -- wingtips were fine -- but I'm intrigued by the idea and will probably pursue.
