Just add meat! Preference™grain-free and gluten-free dog food is a base-mix made with sweet potatoes, coconut, pumpkin, celery and more. This natural, human grade 'foundation diet' offers an easy way to make homemade dog food recipes in your own kitchen. Preference meat-free dog food takes care of all the prep work, so you can add whichever meat or fish you would like. Preference dehydrated dog food is an excellent option for dogs who do better without common protein sources (like chicken, turkey or beef), can't tolerate white potatoes, or who just enjoy a little variety.
