Super great food, no matter what kind of wolf blood. Have you tried many and it tastes my dogs (Eurasians, Australia Shephert), Dachshund) prima. Problems, while among themselves change the flavors of White Fang was never there previously. One of my dogs suffering from allergies, but since the change of feed on wolf blood products, there are no more problems. Super suitable as a treat for training. Not the best food, but it's worth it to me and my dogs.
