While I'm not positive it's the exact model modeled by this cute pup (since the picture was too fuzzy to zoom), I can certainly see Matthew McConaughey picking out an eco-tastic collar like this one — it's constructed with yarns made from recycled plastics. Way to just keep livin'.

For just $13, your pampered pals can have a heavy duty gold or salmon colored collar and, if you're not in a leash-free zone, a matching lead, too!
