Yes - I had emailed asking if their food contained ethoxyquin and that Peter you mentioned emailed back right away to say that there is no ethoxyquin.
I bought the sample bag and my dogs love it so I might give it a try - perhaps my dogs allergies are related to the protein in grains and so I'd like to see how she does on this.
Mind you, I feel a little like I am experimenting with them since these grain-free foods are a relatively new concept. Although it is one that makes complete sense to me - I've never seen a carnivore cook up rice and barley to have along with their meat!
