Our Newfoundlands are fed the raw diet. They are given a combination of 'Abby's Choice', Frozen Bil-Jac, raw chicken and turkey, eggs, yogurt, cottage cheese and Nature's Pharmacy Newf Rescue.
A good book to read to learn more about this diet is 'GIVE YOUR DOG A BONE' by Ian Billinghurst. You can find this at amazon.com. It is easy to read and will help you understand the rationale behind the raw diet.
