A marking syringe which allows an individual using the syringe to inject a fluid such as a vaccine into an animal and, at the same time, mark the location of the injection on the animal. More specifically, the marking syringe includes a vaccine syringe and an ink syringe connected to a handle. Activation of the handle simultaneously activates the vaccine syringe and the marking syringe. The vaccine syringe and the ink syringe are respectively connected to a source of vaccine and a source of ink. After connection to the vaccine and ink sources, the syringe needle is inserted into the animal and a syringe handle is actuated. As the handle is actuated, a vaccine syringe and an ink syringe both discharge their contents. The position of the ink syringe relative to the vaccine syringe is such that the discharged ink marks the animal in the approximate location of the vaccine injection.
