I feed raw to Dance. It is more expensive than feeding her kibble, but just slightly. Eventually I plan on buying from the local raw co-op type company once I get a dog freezer, but even then it will still me more than feeding kibble. Especially for all three.
That said, it's definitely worth it to me if you can afford it. I don't really see that much of a difference in Dance's health, but I feel better not giving her processed kibble daily. And also, her breath is evidently much better on raw. I gave her kibble the other night for the first time in months and she smelled so fishy and icky... and it wasn't even a fish based food. Her coat is softer on raw too. I wish I could switch the Dobermans over just to see if their slight doggy body odour would go away, but I can't yet.
