Hi Kate!
I have fed grainfree foods for almost 20yrs. I thought it was the best. The DCM scares me. If you are on Facebook, join the group Taurine-Deficient (Nutritional) Dilated Cardiomyopathy. It is run by professionals and chock full of information. It is recommended to feed a grain inclusive food that follows WSAVA (World Small Animal Veterinary Association). Currently, the only foods that do that are Purina, Royal Canin, Eukanuba/Iams and Hills Science Diet.
I look at it this way: better to be safe than sorry. I don’t have to feed this food forever but I am until we know exactly what’s causing this.
