The dog food market is dominated by two names - Purina and Pedigree. Meaning the only way for either to grow, is to steal share off the other.

Meanwhile, dog owners are very loyal to their brand of dog food - unless it's making their dog unhealthy.

A little known way to find this out is by analysing your dog's shit. With that in mind, this spec idea suggests a way for Purina to come out on top.
