Hello all:
December 14th the Skeptvet posted an update concerning the DCM alert following the publication of two studies, one of which included several of his patients, “Evidence Update: Grain-free and other “BEG” Diets Associated with Heart Disease in Dogs” along with a new bottom line summary:
“Bottom Line
We cannot say with certainty that BEG diets cause heart disease. We can only say that they have been associated with DCM in both golden retrievers with taurine deficiency and in other breeds without taurine deficiency. We can also say that changing diets appears to have benefitted some of these dogs, though many other treatments were employed at the same time, which limits out ability to know how important a factor this diet change was in the dogs’ recovery.
We can also say that none of the claims for health risks from grains in pet foods, or for health benefits from grain-free or other BEG diets, are supported by any reasonable scientific evidence. Certainly, the evidence for such diets is weaker than even the very limited evidence against them.
As pet owners and veterinarians, we need to proportion our confidence in any conclusions to the strength of the available evidence and be willing to change our minds as new evidence emerges. We also need to make our decisions now, even before we have perfect evidence. Right now, there is no solid reason to think grain-free diets have any health advantages, and there is weak evidence to suggest they might have health risks for some dogs. If you have a golden retriever, it seems reasonable to avoid the diets that have been associated with taurine deficiency and DCM in this breed. Even if you don’t have a golden, you should at least give some thought to why you might want to feed or avoid BEG diets. The evidence can’t make the decision for you, but it should certainly be considered.”
