I have a friend who is a veterinarian in general practice. Her husband is a veterinary cardiologist. She called me last year to report what they were seeing and to warn me off of grain free foods. Vets do not get kickbacks for recommending foods, BTW. Also, this DCM issue is very real - my cardiologist friend has seen it firsthand.
While it’s true that vets don’t get a lot of training in nutrition, they do see hundreds of dogs in their practice, and they get a good feel for what foods work well and also the ones that don’t. For instance, my general vet friend tells me that she sees tons of diarrhea issues with Blue Buffalo food. She also says that the dogs that she sees that eat Pro Plan look great and tend not to have food related issues, so that is usually what she generally recommends to her patients.
By comparison Dog Food Advisor, which rates dog foods and many, many people take as gospel, is an internet site that is run by a dentist. A human dentist.
I am also a member of the DCM Facebook group - there is lots of really good information there for those who are interested.
It is fascinating how many people don’t want to believe that this is an issue. Conspiracy theories against vets and the Big Four dog food companies (Purina, Hills Science Diet, Eukanuba/Iams, and Royal Canin) abound. If you are interested in why these particular companies are considered safe then you can find that information on the Facebook group.
Grain free and boutique food producers are really fighting back on this - they have a lot to lose. There are also many, many boutique dog food stores whose sole business model is selling grain free and exotic foods. In the last week I have seen Facebook posts from two such stores and both have totally misrepresented the FDA advisory.
In full disclosure, I fed grain free foods for many years, and also fed boutique diets. I thought they were superior to the Purina Pro Plan that my breeder recommended. When I lost two of my dogs at a relatively young age (to cancer, not DCM) I was pretty demoralized and spent a lot of time second guessing the choices I had made. I sat down and thought about the oldest dogs that I knew (I knew a lot of dogs, was competing in dog sports and had lots of breeder friends). To a dog, the very oldest dogs were eating Purina Pro Plan, and had for their whole lives. Not a very scientific study, but enough for me. I changed my dogs to Pro Plan and they are thriving. They are 6 and 11, so too early to tell if they will make it to a very old age.
