Eight years ago (can it be?) I started walking our dog with Syd and his five, in a wonderful wide-open setting that involves driving a few kilometers. It quickly became clear that the back of the folded-down rear seat was not designed to support a dog, so I glued some old door mats to a scrap of thin plywood and have been using it to doggify the vehicle ever since (removing it to accommodate biped passengers I call de-doggifying).
Somehow recently I got the idea I could do better. Got the lumberyard to cut to fit a piece of MDF (medium density fiberboard) which I sealed with various products that have been sitting on a shelf in my workshop for years, used the last of a caulk tube of glue to attach new doormats (felpudos) ordered from Mercado Libre, and voilà.
A little easier on the eyes, for sure.
