An article about veterinarians that pretty much sums up how I feel:

13. i have always fed my dogs purina.

my vet says- purina is an old and reliable company that has always done tons of research, and regularly meets the standards of zoos and farms.
my daughter, who works at a big box pet store- the inside name for purina- dog don't die.

my data points- my dogs have almost all gotten tortuously old.

good r&d is the root of corporate growth. corporations absolutely have an incentive to put a quality product on the market. dogs do not live that long. it is easy to see how well they do on any particular brand.

unfortunately i have a dog with a bunch of food allergies, so i have to get the spendy stuff.
i'd be back on purina one in a heartbeat if i could get this guy straight.
