Abstract: A dispenser for administering liquid or paste medication to a horse has a hollow tube open at one end for insertion of a plunger rod and is closed off at an intermediate location by a stop, with an upward-pointing aperture for ejection located adjacent the stop. The tube is supported at each end by members attachable to a bridle, with the tube and support members simulating normal components of a bridle. For liquid medication the liquid is introduced into the tube through the ejection aperture, with the plunger rod in place. For paste material the medication is introduced axially into the open end of the tube by a tight-fitting syringe, and the same syringe is then used to eject a portion of the medicine. Ejection is then completed by removing the syringe and inserting the plunger rod to eject the remaining material.
