One of my dogs is on a full-raw diet. The other two (my parents' dogs who I care for) eat about 25-50% kibble, depending on several factors, and the rest is either cooked food or raw. My dog has been on at elast 1/2 raw for his entire life, and the other two have been eating that way for several years now. I've been watching the DCM issue carefully, despite the small proportion of my dogs' diet that kibble makes up - and the kibble they do eat is not on that list and has fared well through this whole thing so far. They all get full blood panels done yearly and everything has been perfect so far.
Balancing a fresh diet can be difficult, especially in the beginning. But ultimately I can't imagine feeding a diet solely made up of kibble. I never liked the idea anyways, just because it is so processed, and boring on top of that. Could I theoretically live off of cereal? Probably. But would I want to do that? Would that be best for me? Nope. And that's been my dumbed-down view on kibble ever since I became old enough to understand basic nutrition. This whole issue just reaffirms to me that kibble is not the way to go. I realize that's a strong and controversial opinion, but it is my opinion. And I'm not saying Purina vs Champion or anything like that. Kibble is a fad - a fresh or raw diet is not. Even my mother, who up until recently used to tout Alpo and give me a hard time about not just free-feeding all of the dogs dry Alpo kibble, was talking to me about how fresh food might be the way to go, afterall.
With that said, I can't afford to feed 230 pounds of dog a raw/fresh diet as this stage in my life. So my small dog gets only raw, and the big dogs get as much fresh food as possible. So I'm 100% not saying that people who feed kibble are necessarily doing anything bad or wrong or that they shouldn't - I feed kibble, too. I just think that at the end of the day, kibble is something to increase convenience for pet owners, and decrease cost of owning the pet - not the best option for the dogs themselves in most cases.
Dog food companies are going to do whatever they can to make the most money, whether it's what they should be doing or not. Whether they are knowingly hurting our pets or not. They will only stop IF they get caught. Some companies start out with health first as their philosophy, but I can't think of a company that didn't eventually start to cut corners in one way or another. So yeah, let's say they figure out what's causing the DCM issue....they'll stop using that/those ingredient/s and be on to the next cheap thing that shouldn't be in our pets' diet in the first place.
