We are going to go for the jugular here and just say: tracheas get a bad rap. They are notoriously greasy and smelly... but not ours and you don’t even need to take it from us! Our reviews prove it. We have all the seals, certifications and promises as the other guys: 100% Sourced & Manufactured in the USA, No Chemicals, Fillers, Artificial anything, Hormones, Antibiotics, Byproducts, Dyes, Flavors or Preservatives — but what truly makes our Beef Trachea Chews different is this: we perfectly slow roast unprocessed beef trachea at its peak nutritional moment making our trachea chews closer to nature than the other brands — nothing added, nothing removed & a perfect way to keep your canine’s canines primally healthy. Beef Tracheas are known as a superlative source of low fat protein containing glucosamine & chondroitin. **International Retailers - Please note this product contains animal byproduct which we cannot export to countries outside of the United States.
