Tripe is highly nutritious, containing plenty of enzymes, good bacteria, and nutrients that are excellent for your dog's health. Tripe has a strong smell, which is appealing to dogs and might be a good choice for the "picky eaters". Feeding tripe frozen minimizes the smell for us humans. Our Tripe Blend also contains human-grade chicken and bone (ground in) and liver for an excellent complete diet. It also comes in convenient 1/4 lb pre-portioned blocks.
