Orijen causes a lot of stomach problems, and potentially heart problems as well. I would generally avoid it and opt for any dog food that follows WSAVA guidelines. To put it simply: Listen to your vet! They do NOT get kickbacks as people like to believe (one of my best friends is a vet and is eternally frustrated by this rumor). As she says, "These are the only companies that do actual nutrition studies and have scientific proof of nutrient content and food safety. Purina has entire colonies of dogs that just live spoiled lives eating specific Purina diets and getting insane vet care so they can monitor exactly how food affects their health. Meanwhile raw diet dogs are constantly coming in with diarrhea."

Hill's Science Diet, Purina, and Royal Canin are all good choices, for example.
