That's nice to have a local product like that. Be careful with tracheas or anything close to and including a neck of any animal. There can be thyroid hormone around that area of the throat or neck and they can develop hyperthyroidism...very dangerous, even deadly! Perhaps they clean the tracheas well before making them into treats. I do not know.A young man at our local farmers market makes a variety of dog treats, from trachea to monster bones. Tonka will jump thru hoops for his dried chicken wings.
And I gotta admit that I'm a little paranoid about buying elsewhere.
