When your dog's teeth start rotting out, you've only got a few options. You can fit him with dentures, which apparently only come in the shape of human teeth. Or you can give him Dentastix, the oral-care treats from Pedigree. The TV commercial, by TBWA\Chiat\Day, will have people chuckling, for sure. But again, the real winner here might be the Denture Your Dog Web app, from Catapult Marketing, where you can upload your pooch's headshot, pick one of six denture designs, add some audio, share with friends—and await confirmation that this is indeed the greatest thing ever invented.
