There is a big concern these days with grain-free dogfood in relation to DCM. Many of the top lines of dog food manufacturers have been listed as contributors and yet they were not specific to the particular flavor and ingredients. I have seen many of my dogs suffer from allergies with grain and yet, these prime dog foods may prevent the absorption of an essential amino acid called taurine. After a thorough investigation, the FDA(who does not regulate dogfood) said the first report was not conclusive. I am continuing to feed my dogs a grain free and then integrate in a portion of grain. Do your own research and make educated choices. There are so many choices and prices that it’s difficult to know which dog food to use. I still refer to a 3rd party www.dogfoodadvisor.com for an unbiased input of dog food quality.
