I agree with what already has been said. If you go to the websites for the food you are interested in I think you can get samples direct from them. Canidae is a great food and so is Blue but all dog/puppies are different. Fiona could not eat either of those because they both gave her very loose stool. I never tried Royal but tend to agree that there is no need for a food that has "boxer" on it, it is suppose to be the shape of the kibble for the shape of their mouths but Fiona has never had a problem eating anything she wants to...
