While feeding the dog this month, I noticed that some of the pellets of the "Pedigree's Adult Dog Food" were crafted in the shape of bones. On first sight all seems very logical - dogs are known to love their bones hence shaping food in that shape should increase its appeal to the dogs. Except that the pellets are tiny (less than an inch in length) and my dog doesn't seem to appreciate the aesthetics of its meal - it just gobbles.
Realization dawns that the shape of the pellet is designed to appeal to the human customer and not necessarily to the canine consumer. The dogfood people do their jobs: massage our egos to get to our wallets. And I have come to appreciate the crucial role product design plays in the the overall marketing strategy.
