Heartland Premium LLC of Omaha, Nebraska has been in the pet bone and treat business for over 12 years. Heartland Premium takes great pride in the fact that our treats are produced from USA Born, Raised, and Harvested cattle including Angus and/ or Angus/Herford cross bred cattle. Heartland products are produced from young cattle raised within 500 miles of Omaha, NE. Our TREATS are from Angus or Angus/Crossed Herford cattle that are 29 months old or younger. A USDA requirement for Prime beef. All of our bone products come from our plant here in Omaha. We slow roast our TREATS at a low temperature of 210 degrees for 30-36 hours and then spray a light mist of Liquid Charcoal smoke to give our products a golden brown look your dog will love. Each piece is hand trimmed.
