Simple, reliable means of medicating, vaccinating or tranquilizing livestock.More Videos

The StockDoctor is a pole-type syringe of durable and simple construction.  Using the StockDoctor is easy.  Simply push the needle end into the animal.  The device releases the full dose of the medication gently as the animal moves away.  When the animal gets past 25 feet, the syringe is pulled free by a retractable tether line and is retrieved.  See the StockDoctor in action!  Read more about the StockDoctor in the StockDoctor Owner’s Manual.
