Agree with WylieMom on everything
I would never feed Iams, btw. Ever. Their animal cruelty stuff is enough to make me not feed it. I'd feed Purina over Iams, even though I don't like Purina either.
I would
never condone feeding a dog a vegan diet. It's completely unnatural for a canine and it cannot be healthy. I do not eat raw food for myself, and probably never would, but it's simply because I don't like it (I don't like the taste of sushi, etc) and have not researched it enough for humans... but I do know some people do the raw diet thing for themselves.
I'm not comfortable with prey model raw simply because I don't have the freezer space, the money, the knowledge, or the time to prepare it. I love pre-made raw because it's all done for me, pretty much, and it's pretty easy and convinenant. I feed pre-made raw a few times a week for breakfast for Jackson, and Orijen or Acana kibble for dinner. So far, he's in fabulous health at a little over 2 years old. His coat is super shiny and soft (and he always gets compliments on it- though he has short hair), his teeth are great, his energy levels are great, he's never had ear infections, or things like that, his bones and hips and everything are in perfect shape. I'm incredibly pleased with his diet and am especially happy w/ it when I see my family members dogs eating Kibbles n Bits and Iams, etc, who have constant rashes, bumps, hot spots, throwing up often, overweight, scabby looking things on their body, bad hips and joints, and disgusting breath.
