Pork hearts, in fist size portions great for your dog to chew on
Heart is one of the most nutritional muscle meats. It is rich in iron and zinc, and is a great source of thiamin, vitamin B6 and B12, phosphorus, copper and selenium. However, heart is quite high in cholesterol, so don’t feed it to your dog too often. It should make up to 10% of your dog’s raw meat diet.
